1. Unit 1 Vocabulary Earth System Processes

2. Compaction
Sedimentary rock-forming process that occurs when small layers of small sediments become packed down by the weight of layers above them

3. Crystal
Solid, made up of molecules arranged in a regular and repeating pattern

4. deposition
Process which wind, water and gravity leave eroded sediments in new locations

5. Movement of sediment by wind, water, ice or gravity
erosion
Movement of sediment by wind, water, ice or gravity

6. glacier
Large mass of ice and snow that exists year-round and is involved in erosion

7. Rock made from cooled magma. This is one of the 3 main kinds of rock.

8. The downward movement of rocks, soil, debris and earth.
Landslide
The downward movement of rocks, soil, debris and earth.

9. metamorphic
Rocks created by high pressure and high temperature. These rocks are created deep in the Earth’s crust.

10. Rock cycle
The process that changes rocks into different types of rock over a long time or geologic ages

11. sedimentary
Rocks formed when sediments are pressed and cemented together naturally over millions of years

12. sediments
Small pieces of material that have broken off of rocks and have been deposited by wind, water or ice.

13. Uplifting
The upward movement of the Earth’s crust. This is how many mountains are formed.

14. weathering
Process by which wind, water, and ice wear down rocks and other exposed surfaces; includes chemical and mechanical weathering
