Lithosphere Review-Part 1
Across
- 4. A tectonic boundary between where two plates spread apart from each other
- 8. Thickest less dense part of earth’s crust that makes up the land.
- 11. The weak flexible upper layer of mantle on which the lithosphere moves
- 14. Small particles of rock and soil (sand is an example)
- 15. Thinnest, densest, iron rich crust that subducts on the ocean floor
- 18. A tectonic plate boundary where two plates collide or come together
- 21. magma that reaches Earth's surface
- 23. a naturally occurring, inorganic solid made of up one or more elements that has a crystal structure and a definite chemical composition
- 24. molten rock under the surface of Earth
- 25. The process by which sediments are pressed together under their own weight.
Down
- 1. The process in which dissolved minerals crystallize and "glue" particles of sediment together with water
- 2. Scientific scale that measures hardness of minerals
- 3. The breaking down of rocks and other materials on the Earth's surface.
- 5. process of weathering, wearing down, and movement of rock and soil by wind, water, or other natural agents.
- 6. The largest part of Earth’s interior, made of molten rock with convection currents
- 7. a type of rock that forms from the cooling of molten rock at or below the surface
- 9. the process that converts sediments into solid rock by compaction or cementation
- 10. rock that forms when sediments are compacted and cemented together
- 12. geologic process by which rock is formed and destroyed
- 13. A tectonic boundary where two plates slide past each other without creating or destroying crust (AKA strike-slip boundary)
- 14. The loose, weathered material on Earth's surface in which plants can grow (made up of silt, clay, sand, organic matter, water and air)
- 16. a combination of one in more minerals which have lithified, the type is named by how it forms
- 17. a type of rock that forms from an existing rock that is changed by heat and extreme pressure
- 19. Any substance that cannot be broken down into simpler substances
- 20. The innermost, densest part of earth interior, iron and nickel
- 22. Smallest particle of an element
