L 1.2: Using Fossils to Understand Earth

  •  What do you already know
     about fossils?
  • Fossils: Fossils are evidence of life from the past
    • Fossilized bones, footprints, and leaf prints can reveal clues about the characteristics of ancient life.
  • Fossils are made when living organisms die and their forms are preserved in hard, solid rock
Meet a Paleontologist
  •  Fossils are like time capsules.
    • Scientists use fossils to better understand what Earth was like when that fossil formed—hundreds, thousands, or even millions of years ago!
  •  Dr. Wilson
    •  Associate Curator at the
       University of Michigan Museum of
       Paleontology. 
    • He is a real-life scientist who is investigating fossils to tell the story of Earth’s past.
  •  Paleontologist: a scientist who studies fossils or bones that are embedded in rocks, in order to learn about the history of life on Earth.
Meet a Palentologist
  •  What kind of evidence does Dr.   Wilson use in his research? 
  • How does his research help us learn about the geologic history of Earth?
Unit Question
Why are fossils of species that once lived together found in different locations on Earth now?
  • Dr. Wilson studies fossils to learn more about the history of life on Earth. 
  • Like Dr. Wilson, you will be using fossils to guide your investigation of what Earth was like in the past.
  •  In this unit: 
    • You will be using your understanding of geology to explain what happened to the rock that the Mesosaurus fossils were found in
    • Why the fossilized remains of these reptiles that once lived together are now found so far away from each other.
  •  Our Task:
    • To understand more about the land where Mesosaurus fossils are found and look for clues that will help us learn about Earth’s past.

Chapter 1 Question
What is the land like where Mesosaurus fossils are found?

  • Some aspects of this unit are fictional: 
    • The Museum of West Namibia and Dr. Moraga, the lead curator at this museum 
    • They are included in this unit to give you an opportunity to collect data and communicate your findings in ways that are very similar to the ways that scientists do their work.
  • The fossil specimens of Mesosaurus are real, Dr. Wilson from the video is a real-life scientist who works with fossils to learn about Earth’s history, and the mystery that you are going to investigate is real.
Warm Up: Unit Question
Why are fossils of species that once lived together found in different locations on Earth now?
  •  Notebooks and computers today! 
  •  In your notebook, give a RAE response to answer this question to the best of
     your ability.
  • Geosphere: the solid part of our rocky planet. 
    • In your investigations as student geologists, you will focus on learning more about what the geosphere on Earth is like.
Investigative Question
What is the land like underneath Earth’s surface?
** Answering this question will help us learn more about the geosphere as we work toward figuring out why the Mesosaurus fossils, found in rocks on Earth, are so far apart now **
Scientific Drilling
  • One way scientists learn more about the outer layer is to use large drills to collect samples of the land below the surface. 
  • They work in large teams to operate a drill that can drill many kilometers into Earth from the surface. 
  • As they drill, they take material from below the surface and bring it up to observe and analyze. 
  • The material they take is called a core sample. 
    • Scientists analyze the core samples to learn more about the outer layer.
Scientific Drilling
  • The cross sections we will look at today show what you would see if you cut through the outer part of Earth and show what is inside, just below the surface. 
  •  Core samples collected from drills allow us to see a small portion of the inside of Earth. 
    •  Scientists can use this information to make cross-section diagrams of what is found just below the drilling site.
Cross Section: A diagram that shows what the inside of something looks like
Investigative Question
What is the land like underneath Earth’s surface?
  •  Is Earth's surface covered with the same materials?
  •  What was different about each scientific drilling site?
  • What is the same for all the drilling sited we examied?
Scientific Drilling
  •  Different places on Earth look different on the surface and can have different coverings like water, dirt, etc. 

  •  No matter what is on top, if you drill down deep enough, you will find hard, solid rock. 
Outer Layer: Earth’s outermost layer of hard, solid rock that is underneath the soil, vegetation, and water

  •  How does this representation show your best thinking about what you know about the land so far?
We know that:
  •  There is a boundary separating the land where Mesosaurus once lived.
  •  Earthquakes are caused by plate motion, so what kind of plate movement occurred at this boundary?

Level 1 Response
Earth’s entire outer layer is made of hard, solid rock. This outer layer is divided into plates. Continents are parts of the plates, and the plates move. The two continents are on different plates that are moving toward each other.
Level 2 Response
Earth’s entire outer layer is made of hard, solid rock. This outer layer is divided into plates. Continents are parts of the plates, and the plates move. The two continents are on different plates that are moving toward each other, which means there is a convergent plate boundary between these two plates. At this convergent plate boundary, one plate moves underneath the other and sinks into the soft, solid mantle.
Level 3 Response
Earth’s entire outer layer is made of hard, solid rock. This outer layer is divided into plates. Continents are parts of the plates, and the plates move. The two continents are on different plates that are moving toward each other, which means there is a convergent plate boundary between these two plates. At this convergent plate boundary, one plate moves underneath the other and sinks into the soft, solid mantle. However, Diego’s little brother does not need to worry that the two continents will run into each other because plates move very slowly, and it takes millions of years for plates to travel great distances.

Lesson 2.1:
Considering What's Underneath Earth's Plates
Investigation Question
How do Earth's plates move?
Earth's Mantle
  •  In the sim we could change the
     hardness of the mantle from
     hard, solid rock to soft, solid rock.
  •  Notice what happens with the plates when the mantle is set to hard solid rock vs. soft solid rock.
Earth's Mantle
  •  Mantle = the layer of soft, solid rock just below Earth's plates. 
    •  Starts between 65 - 100 km     below Earth's surface
    •  Also made of solid rock
What are some examples of hard solids vs. soft solids?
Modeling the Mantle with Silly Putty
  •  Based on our experience with silly putty, how would you describe the soft, solid rock that makes up the mantle?
  •  How do you think the soft, solid mantle allows the plates about it to move?
Warm Up: Word Relationships
  •  Some visitors at the Museum of West Namibia have never learned anything about Earth’s plates, plate boundaries, or mantle. Use the Word Bank to create sentences that help explain to these visitors how these parts of Earth work together using scientific language.
  •  With your partner, create at least two sentences that answer both of these questions using at least two words from the word bank: 
    •  How can Silly Putty and a hard, plastic cube be used to model different layers of Earth? 
    • How are Earth’s plates able to move?

Lesson 2.2
“Listening to Earth”
What happens to the plates and the mantle at plate boundaries?
  •  We have learned that:
    •  Plates can move because they are on top of the
       soft, solid mantle. 
    •  We also saw evidence of plate movement at the
       plate boundaries when we observed earthquakes
       in the Sim
  •  Now, we are going to focus more specifically on what happens to the mantle and the plates at plate boundaries. 
    •  Once we have a better understanding of this, it will bring us closer to
       assisting the Museum of West Namibia in determining what type of
       plate movement got the Mesosaurus fossils where they are today.
Active Reading: “Listening to Earth” article
  • Dr. Moraga from the Museum of West Namibia sent us an article. 
    •  It is about a scientist and his
       team who are investigating plate
       boundaries found on the ocean
       floor. 
    •  This article will help you
       understand what happens to the
       plates and mantle at plate
       boundaries.
Discussing Annotations
  •  The article talked about a scientist who is studying two types of plate boundaries: Convergent and Divergent boundaries
Convergent
Divergent
  • Boundaries where two plates are moving toward each other. 
  •  One plate is slowly forced underneath the other
  • Boundaries where two plates are moving away from each other. 
  •  The mantle material cools, hardens, and adds onto the edge of each plate.

Global Positioning System (GPS)
What do you already know about GPS?
ff80808156...80c3bd1b89
  •  GPS receivers on Earth can accurately measure the small distances that plates currently move.
  •  Since the 1970s, scientists have used measurements from GPS taken over a period of time to calculate the rate of plate motion. 
  •  We can also use GPS data to think about the rate of plate motion by calculating how fast or slow two plate are moving together or apart.



  •  Looking at the map, what do you notice about the current rate of plate motion at different boundaries on Earth?
Plate Motion Simulator
  •  We know that Earth's plates are moving at an average rate of only a few centimeters per year.
    •  Over long periods of time do the plates move at similar rates?
  •  When we compare calculated data used in the Sim to rates of plate motion happening today, we will look for patterns.
    •  Patterns in rates of change can provide evidence about natural systems (Earth's plates).
Plate Motion Simulator
  • How slowly do plates move? 
    • Use the Sim to measure how far plates move from each other over time and use your measurements to calculate the rate of plate motion. 
    • On one device, open the Plate Motion Sim. 
    • On the other device, leave the direction screen open. 
  • Go to Region 2 of the Sim. 
    •  Add a GPS marker to each plate as close as possible to each other and to the plate boundary.

A.) India and Australia are parts of different plates. The
      plates slowly moved apart as new plates from
      underneath got added between them over millions
      of years.

B.) India and Australia are parts of different plates. The
      plates slowly moved far apart as soft, solid rock from
      underneath got added to the edges of the plates
      over millions of years.

C.) India and Australia are parts of different plates. The
      plates floated away from each other across the   
      ocean.

D.) India and Australia are parts of different plates. The
      plates were sometimes pushed far apart by
      earthquakes, and soft, solid rock from underneath
      got added to the edges of the plates.

Lesson 3.2:
A Continental Puzzle
Investigation Question
What evidence do we have of past plate motion?
** Understanding past plate motion will help provide a complete explanation of how the Mesosaurus fossils got separated **
Active Reading: A Continental Puzzle 
  • Alfred Wegener, a scientist who lived around 100 years ago, and the work he did that led modern scientists to be able to explain what happens to the plates and mantle at plate boundaries. 
  • Wegener also used fossils in his work, so reading this article will help you to better understand our own Mesosaurus mystery.

  • The Jalisco Block is a small section of the North American Plate.
  • Based on the evidence you’ll consider in this chapter, you’ll learn why scientists do not agree on what is happening with the movement of the Jalisco Block.
What patterns do you notice?
  • The GPS data is inconclusive as to how the Jalisco Block is moving. 
  • Because of this, many scientists have gathered data and other information about this area to try to figure out what is happening there.
What best explains the pattern of volcanic activity and earthquakes on the Jalisco Block?
Divergent movement of the Jalisco Block away from the North American Plate best explains the pattern of volcanic activity and earthquakes on the Jalisco Block.
Convergent movement between the Jalisco Block and the Rivera Plate best explains the pattern of volcanic activity and earthquakes on the Jalisco Block.has been classified in diverse ways

Examining Evidence Cards
Discussion Questions 

1.) What does this evidence tell
      you about whether the
      Jalisco Block is moving? 

2.) What does this evidence tell
      you about which kind of
      movement might cause this
      geologic activity?
Examining Evidence Cards
  • Rifting is the divergent movement, or spreading, of plate material in the interior of a plate. 
  • Rifting can mark the beginning of a new divergent plate boundary, just as when the Mid-Atlantic Ridge began to form between South America and Africa many millions of years ago.
  • This plate boundary ultimately separated the Mesosaurus fossils by thousands of kilometers and formed a new ocean basin. 
    •  However, sometimes rifting starts and then slows down or stops. 
    • A famous example of this is the Baja California Peninsula, which separated from Mexico due to divergent movement but did not form a new divergent plate boundary. 
Evidence Card B: What do you notice about the pattern of volcanic activity on the Jalisco Block? 

Evidence Card C: What does this evidence tell you about the boundary between the Rivera Plate and the Jalisco Block? 

Evidence Card D: How can the movement of two plates form a trench? 

Evidence Card E: What can the pattern of recent earthquakes tell you about plate motion on the Jalisco Block?
