| Question | Answer |
|---|---|
| what are the four main layers of the Earth | Mantle, inner core,outer core, crust |
| is a solid ball with the radius of about 1,220 km. (a solid sphere in the fluid core such as the iron-nickel core.) | Inner core |
| Is a liquid layer about 2,266 km composed of iron and nickel that lies about Earth's solid inner core and below the mantle | Outer core |
| _____ does not change much from one part of the mantle to another, however, physical conditions change because of pressure and temperatures increase with dept. | Mantle |
| The _______ is Earth's layer, including both land surface and the ocean floor. The ____ averages 32 km thick. Composition- oxygen, silicon, aluminum, calcium, iron, sodium, potassium, and magnesium. | Crust |
| a rock that makes up core of the continents | granite |
| the material that forms Earth's hard surface | rock |
| the force pushing on Earths surface or area | pressure |
| the study of planet Earth | geology |
| one of Earth's great landmasses | continent |
| a wave produced by an earthquake | seismic wave |
| a force that builds up features of Earth's surface | constructive force |
| a rock that makes up much of the ocean floor | basalt |
| what is the difference between oceanic continental crust? | The oceanic consist of mostly of dense rocks such as basalt; Continental crust forms the continents and consists mainly of less dense rocks such as granite. |
| who created the theory of continental drift | alfred weagner |
| did scientist aprove of this theory, yes or no | no |
| name the proof alfred weagner had | from fossils, landforms, climate |
| true or false, is the inner core as hot as the sun | true |
| true or false, the deeper you are in the Earth the more pressure and heat there is. | true |
| true or false, oceanic crust is thinner than continental crust | true |
