Earth Formation

7. Earth land masses
8. A thin layer of gases surrounding Earth
9. largest layer of the earth. This layer contains hot rock, below the crust.
11. Earth's outermost layer.
12. A group of parts that work together as a whole (Such as the Earth)
13. Earth's outermost layer.
16. Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
17. A plate boundary where two plates move away from each other.
19. A plate boundary where two plates move past each other in opposite directions
20. The transfer of energy by electromagnetic waves
21. Core layer of a dense sphere of solid iron and nickel at the center of Earth. It is solid due to immense pressure

1. A plate boundary where two plates move toward each other.
2. The name of the single landmass that broke apart 200 million years ago and gave rise to today's continents
3. core layer of molten metal, movement of the liquid causes Earth's Magnetic Field
4. the ability to do work
5. A usually light colored igneous rock that is coarse grained and found in continental crust
6. Forces that Build up Earth (Volcanoes & Earthquakes)
10. dark, fine grained, makes up oceanic crust
14. Forces that Wear away land (Weathering & Erosion)
15. All the water on earth
16. Occurs in mantle and outer core, heat transfer by movement of a liquid
18. Force which pulled dust, ice, and gasses together to form Earth
