Across
- 5. water located beneath the Earth's surface that fills the spaces within soil, sand, and rock, often stored in underground layers known as aquifers
- 6. a single bed of sedimentary rock, generally consisting of one kind of matter representing continuous deposition
- 9. the continuous, endless movement of water on, above, and below the Earth's surface
- 12. a continuous, underwater mountain range formed by tectonic plates pulling apart at a divergent boundary
- 13. the geological process occurring at divergent plate boundaries where new oceanic crust is created, causing tectonic plates to move apart
Down
- 1. any water that collects on the surface of Earth
- 2. the movement of Earth's continents relative to each other
- 3. the scientific theory that Earth's outer shell (lithosphere) is divided into several large, rigid plates that glide slowly over the mantle's asthenosphere
- 4. natural events that threaten lives, property, and other assets
- 7. When soil is moved from one location to another by wind or water. After rocks have been broken down, the small particles are transported to other locations by wind, water, ice, and gravity.
- 8. the physical or chemical breakdown of rocks and minerals into smaller pieces or aqueous solutions on Earth's surface
- 10. An ocean trench is defined as a long, narrow, and extremely deep depression in the seafloor that marks the deepest parts of the ocean, typically formed at convergent plate boundaries.
- 11. the record of geologic time, divided into eons, eras, periods, epochs, and ages
