| 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 |
