Earth System's Vocabulary
Across
- 2. A tool that measures/ records details of earthquakes.
- 4. The study of earthquakes and related phenomena.
- 5. Below the lithosphere. Hotter and more fluid part of mantle.
- 7. Petroleum, natural gas, coal. Made from remains of plants & animals.
- 9. Boundary where tectonic plates divide.
- 11. Group of animals that occupy a certain area.
- 12. Water held underground in the soil in deep reservoirs.
- 14. When magma flows through a crack in the middle of a tectonic plate, & not at a plate boundary. Hawaiian islands were formed this way.
- 17. Move side to side through ONLY solids. Travel slower than P waves.
- 18. Compress or squeeze through solids & liquids. Travels faster than S waves.
- 19. The movement caused within a fluid when the hotter, less dense material rises, and colder, denser material sinks
- 20. When heat, pressure, cooling, melting, and weathering cause rocks to change from one type to another over time.
- 24. The outer part of the earth. Includes the crust & upper mantle.
- 25. Forms at a convergent boundaries where one plate subducts under another, and magma underground is pushed upward.
- 26. The supercontinent that existed before continents separated.
- 29. When a sudden release of energy in the lithosphere creates seismic waves.
- 30. No longer in existence.
- 31. Forms from pre-existing rock and fossils. Appears layerd.
Down
- 1. The lower part of Earth's mantle, below the asthenosphere.
- 3. Occurs when divergent plate boundaries separate. Convection currents cause less dense material to rise. Creates new ocean floor.
- 6. Still in existence, surviving species.
- 8. Forms when molten rock crystallizes and solidifies. Appears glassy.
- 10. The solid, outermost layer of Earth, lying above the mantle.
- 13. Boundary where tectonic plates slide past each other.
- 15. Large pieces of lithosphere that the ocean & the continents rest on.
- 16. The layer that lies between Earth's crust and core. The majority of Earth's mass is in this layer.
- 21. The innermost layer of Earth. Divided into 2 parts, liquid outer and solid inner. Made of iron and nickel.
- 22. The study of Earth.
- 23. Boundary where tectonic plates collide.
- 27. Forms under extreme heat and pressure. Appears twisted.
- 28. A solid inorganic material found in nature.
