TCAP- Earth systems
Across
- 4. the innermost layer of earth divided into 2 parts, liquid outer and solid inner, made of iron and nickel
- 7. A solid inorganic material found in nature
- 9. still in existence, surviving species
- 11. the solid, outermost layer of earth, lying above the mantle
- 12. compress or squeeze through solids and liquids. travels faster then S
- 15. Group of animals that occupy a certain area
- 16. form at convergent boundaries where one plates subducts under another, and magma underground is pushed upward
- 18. Petroleum, natural gas, coal, made from remains of plants and animals
- 19. boundary where tectonic plates divide
- 20. the study of earthquakes and related phenomena
- 23. forms under extreme heat and pressure. Appears twisted.
- 25. occurs the divergent plates separate. convection currents cause less dense material to rise. creates new ocean floor
- 26. when a sudden release of energy in the lithosphere creates seismic waves
- 28. A tool that measures/ records details of earthquakes
- 30. boundary where tectonic plates collide
- 31. below the lithosphere. hotter and more fluid part of mantle
Down
- 1. forms from pre-existing rock and fossils. Appears layered.
- 2. move side to side through only solids. travels slower then p waves
- 3. the supercontinent that existed before contents separated
- 5. the movement caused within a fluid when the hotter, less dense material rises, and colder, denser material
- 6. when magma flows through a rock in the middle of a tectonic plate, and not at all a plate boundary. Hawaiian islands were formed this way
- 8. No longer in existence
- 10. large pieces of lithosphere that the ocean and continents rest on
- 13. the lower part of earths mantle, below the asthenosphere
- 14. boundary where tectonic plates slide past each other
- 17. The study of earth
- 21. the outer part of earth. includes the crust and upper mantel
- 22. water held underground in the soil in deep reservoirs
- 24. when heat , pressure, cooling, melting, and weathering cause rocks to change from one type to another over time
- 27. forms when molten rock crystallizes and solidifies, Appears glassy.
- 29. the layer that lies between earths crust and core. the majority of earths mass is in this layer
