Across
- 1. Liquid magma that reaches the surface; also the rock formed when liquid lava hardens.
- 2. A naturally occurring solid mixture of one or more minerals or organic matter
- 4. layers Crust, Mantle, Outer Core, Inner Core
- 6. field A field that surrounds the Earth because of earth's convection currents in earth's liquid iron core.
- 8. the layer of the earth between the crust and the core. The Largest Layer of the earth. Makes up 2/3 of Earth’s Mass. Convection currents can be found here.
- 9. The Outer layer of the Earth. Earth’s thinnest layer. Composed aluminum, silicon, oxygen
- 11. Waves Waves (earthquakes) that help us study the inner layers of Earth.
- 14. core a layer of molten iron and nickel that surrounds the inner core of Earth. Earth’s only completely liquid layer.
- 15. core solid, dense center of the Earth. Made of iron.
Down
- 1. the solid, outer layer of the earth that consists of the crust and the rigid upper part of the upper mantle.
- 3. Crust Thicker, less dense crust
- 5. Crust thin, more dense than continental crust, subducting crust
- 7. The solid, plastic layer of the mantle beneath the lithosphere; made of mantle rock that flows very slowly, which allows tectonic plates to move on top of it
- 10. plate (Plate Tectonics) Sections of the Earth's crust that move due to convection currents.
- 12. molten rock in the earth's Mantle
- 13. Current the movement of a fluid, caused by differences in temperature, heated fluid rises, and cooler fluid sinks
