Earth Science

1. Small fragments of rocks and minerals. Examples would include pebbles, sand, silt, and clay.
6. A place where two plates come together or collide. These plates can form mountains or volcanoes.
8. The process of a rock's size and shape being changed by pressure and heat.
11. The process of magma or lava cooling down and hardening as it moves closer to the surface.
13. Type of rock that is formed when sediments are compacted and cemented together.
15. Type of rock that is formed when magma cools below Earth's surface or lava cools at the surface.
16. States that pieces of Earth's crust are in slow, constant motion driven by convection currents in the mantle.

2. A place where two plates move apart, or divide. These plates will form rift valleys on land and sea-floor spreading in the ocean.
3. The process of rocks turning into liquid as they move closer to the core and heat from the core.
4. Deadly ocean waves that form from the sharp jolt of an undersea earthquake or other disturbance.
5. A place where two plates slide past each other, moving in opposite directions. These plates can cause earthquakes.
7. The process by which gravity, water, wind, and ice remove and transport sediment from one place to another.
9. Type of rock that is formed when an existing rock is changed by heat and/or pressure.
10. An event in which molten rock comes out from the mantle to the surface of Earth as ash, lava, and gases.
12. The process by which gravity, water, wind, and ice break rocks into smaller pieces.
14. An event that occurs when plates shift suddenly and release stored energy causing the ground to move.
