ANSWERS

Earth Changes

Review Check- Up #1

1. Label the Earth’s Interior

1. Continental Crust
2. Oceanic Crust
3. Mantle
4. Outer core
5. Inner Core

2. Why is it not possible to travel to the interior (inside) of the Earth?

INTENSE HEAT, PRESSURE, AND DRILLING

3. Define the following concepts

Constructive Force- SHAPES EARTH SURFACE- BUILDS UP LANDFORMS AND MOUNTAINS

Destructive Force- ERODES AWAY MOUNTAINS AND OTHER STRUCTURES ON EARTH

4. Describe Wegener’s theory of continental drift. What evidence did he use to support his theory?

ALL CONTINENTS WERE ONCE CONNECTED TOGETHER IN A SINGLE LANDMASS.

LANDFORMS, FOSSILS, AND CLIMATE PROVIDED HIS HYPOTHESIS CORRECT.

5. Compare and contrast the inner and outer core.

Inner Core  - Dense ball, solid, pressure makes it solid

Similarities- Center of Earth, made of iron and nickel

Outer Core- thick liquid, not as hot as inner core

6. Compare and contrast the lithosphere and the asthenosphere.

Lithosphere - stone, rigid, upper most part of crust / mantle

Similarities - below crust, part of mantle, middle layer of the Earth

Asthenosphere- soft/weak, flows easily, below the lithosphere

7. Why are seismic waves used to help understand the interior of the Earth?

SPEED AND PATHWAYS AND ENERGY RELEASE HELP USE DETERMINE THE INETERIOR OF THE EARTH- WHEN AN EARTHQUAKE OCCURS.

8. Define plate tectonics.

EXPLAINS THE SUBDUCTION AND SLOW CONSTANT MOVEMENT OF THE LITHOSPHERE DRIVEN BY CONVECTION CURRENTS.

Describe at least four ways that the world would be different if we still lived on Pangaea.

OR

Coal deposits have been found beneath the ice of Antarctica. However, coal only forms in warm swamps. Use Wegner’s theory to explain how coal could be found near the poles. Develop two inferences to explain your answer.
