Across
- 7. Small, solid pieces of material from rocks or organisms; earth materials deposited by erosion.
- 8. The broken pieces of the Earth's lithosphere and outer solid shell separated by cracks.
- 10. Process by which sediments are removed by water, wind, ice, and gravity`
- 11. all the water on the earth’s surface
- 13. practice of planting different crops sequentially on the same plot of land to improve soil health, optimize nutrients in the soil, and combat pest and weed pressure
- 15. Currents that drive the movement of Earth's rigid tectonic plates in the planet's mantle.
- 16. Transference of energy through the Earth.
- 17. whole mass of air that surrounds the earth
- 20. The solid part of the Earth that includes the crust and upper mantle
- 22. A trembling and shaking of the earth's surface resulting from the sudden release of energy in the crust, either along fault lines or from volcanic activity.
- 24. Process by which rock is broken down by water, wind, ice, and heat.
Down
- 1. A seismic wave that shakes the ground back and forth perpendicular to the direction the wave is moving.
- 2. Theory that states the Earth's crust broken into plates that float on the upper mantle.
- 3. Underneath the lithosphere in the middle mantle layer composed mostly of molten rock.
- 4. The average weather conditions of an area over time, usually about thirty years.
- 5. A wave that shakes the ground back and forth in the same direction but in the opposite direction as the direction the wave is moving.
- 6. The layer that is beneath the asthenosphere in the lower mantle
- 9. A series of processes on the surface and inside Earth that slowly changes rocks from one type to another type.
- 12. Wegener's idea that there was gradual movement of the continents across the earth's surface through geological time.
- 14. Made of loose, weathered rock and organic material in which plants with roots can grow. The rock material is composed of sand, silt, and clay.
- 18. Naturally occurring inorganic solid with an orderly crystalline structure and definite chemical composition.
- 19. place where all soil formation takes place as a result of the atmosphere, lithosphere, and hydrosphere coming together
- 21. The ability of soil to sustain plant growth and optimize crops.
- 23. The central part of the Earth.
