- 1. A river picks up sediments from its banks and moves them with the current. This is an example of ___.
- erosion
- 2. ___ is the breakdown of solid rocks into sediments.
- Weathering
- 3. ___ is the process by which sediments are removed from a given location, such as a rock face or riverbank.
- Erosion
- 4. ___ occurs when a rock is scraped by rocks or other particles.
- Abrasion
- 5. Scratches from rocks in a moving glacier are signs of ___.
- abrasion
- 6. Mechanical weathering is a ___ process.
- physical
- 7. Acid rain, oxygen, and water can all cause ___.
- chemical weathering
- 8. Dissolution of calcite, rusting of iron-based minerals, and potassium feldspar losing its potassium are all examples of ___.
- chemical weathering
- 9. Quartz sand is very common on beaches because ___.
- quartz is resistant to weathering, so it is left behind after other minerals erode away
- 10. Water increases chemical weathering because ___.
- it facilitates chemical reactions
- 11. The rate of water percolation, the temperature at which weathering takes place, and the type of rock all influence ___.
- the rate of weathering
