QUESTION 6

  1. What evidence did Wegener make use of to develop the theory of continental drift?

2 points  

QUESTION 7

  1. According to the theory of continental drift, which option indicates the order of how the continents changed positions?  Graphic shows 3 world globes. The first one labeled A, shows all the continents on Earth broken up as to how they appear today. The next globe, labeled B, shows one very large piece of large land where all the continents are connected. Globe C shows the continents drifting away from eachother a little bit.

QUESTION 8

  1. The theory of continental drift proposes that the Earth's continents may have once been united as a supercontinent but have drifted apart over time. What was the name of the supercontinent?

    Pangaea

    Laurasia

    Americas

2 points  

QUESTION 9

  1. Over time the original supercontinent broke into two large land masses. What are the names of these two land masses?

    Laurasia and Gondwanaland

    Gondwanaland and Pangaea

    Pangaea and Eurasia

2 points  

QUESTION 10

QUESTION 11

  1. Which term is described as a flat expanse of ocean floor?

    abyssal plains

    deep-sea trenches

    guyots

2 points  

QUESTION 12

  1. Which term is described as a seamount with a flattened top?

    abyssal plains

    deep-sea trenches

    guyots

2 points  

QUESTION 13

  1. Where are the youngest rocks in the Earth’s crust found?

2 points  

QUESTION 14

  1. Iron-rich minerals in rock pointed in one direction and then switched to the exact opposite direction. This supports what idea?

    Earth’s magnetic field stopped working entirely.

    Earth’s magnetic field goes through pole reversals.

    Being underwater makes the rocks respond to magnetic fields.

2 points  

QUESTION 15

  1. How does the ocean floor keep track of magnetic fields?

    All rocks act like magnets

    Basalt is iron-rich and responds to magnetic fields

    Being underwater makes the rocks respond to magnetic fields.

2 points

    reversing paleomagnetism in rocks on the ocean floor

    evidence of ancient tropical swamps in cold regions of North America

    a seafloor that was geologically active with earthquakes, volcanoes, and mountain chains

2 points  

QUESTION 17

  1. Which theory best explains the present arrangement of continents, oceans, and landforms on Earth?

    Wegener's continental theory

    The continental puzzle theory

    the Pangaea theory

2 points  

QUESTION 18

  1. Which description best presents the arrangement of continents, oceans, and landforms according to the theory of plate tectonics?

2 points  

QUESTION 19

  1. Which two forces do scientists believe are responsible for tectonic plate motion?

    friction between the plate and the asthenosphere and pressure of magma on the edge of the plate

    gravity acting on the edges of plates and convection in the mantle

    convection in the mantle and pressure of magma on the edge of the plate

2 points  

QUESTION 20

  1. Which of these statements is true about the theory of plate tectonics and the theory of continental drift?

    The theory of plate tectonics shows that continental movements could not have happened.

    The theory of plate tectonics tells exactly where the continents were before Pangaea divided.

    The theory of plate tectonics shows that Pangaea was impossible, but the continents did move.

2 points  

QUESTION 21

  1. What activates a convection current, starting the flow of a fluid?

    heated liquids at Earth’s surface

2 points  

QUESTION 22

  1. Which of the following is a result of gravity in relation to moving tectonic plates?

    ridge push and slab pull

    circulating material in the mantle

    Earth's internal heating

2 points  

QUESTION 23

  1. How can gravity's role in tectonic plate motion be described?

    ridge push and slab pull

    circulating material in the mantle

    Earth's internal heating

2 points  

QUESTION 24

  1. Which two processess do scientists think move the Earth's lithospheric plates?
