2 1. What is the process called in which rocks break down? 2. What do we use to determine the hardness of a mineral? 3. How are rocks categorized? 4. What is density?

3 The natural movement of material from one place to another.

4 Running Water

5 Wind

6 Waves

7 Glaciers

8 Gravity

9 Moving water carries sediment. Faster the water the larger the sediment it can carry. As the water slows down the sediment drops off.

10 As glaciers move they break off pieces of rock and sediment, pick them up and carry them with them.

11 Mass Wasting - The movement of rock, soil, or snow, down a slope. Controlled by the force of gravity and can happen quickly or slowly.

12 When a mass of material slips down along a curved surface.

13 When sediments move extremely slowly downhill.

14 Rock falls – when blocks of rock break loose and tumble through the air. Rock Slides – when layers of rock slip down a slope suddenly.
