Across
- 2. When plant roots grow it produces weak acids that slowly dissolve rocks around the roots
- 3. the process of when a rock is physically broken into smaller pieces due to this type of weathering
- 5. A mixing of water with carbon dioxide to make carbonic acid
- 6. Refers to the Ava edge weather conditions in an area
- 7. When sand and rock particles get carried by wind, water or ic it can wear away rock surfaces like sandpaper
- 8. When rainwater and burning coal, oil, and gas pollute the air it creates acid stronger then normal rain water
- 11. Iron combined with oxygen in the presence of water which makes rust
- 13. Also known as Pressure release where due to the pressure of surrounding rocks reduces the rock will expand causing cracks to form
- 14. A principle that states that the geologic progresses that operate today can also be operated in the past it’s also what geologists use to make inferences
- 15. It’s also known as clay formation where when certain rocks are exposed to water it slowly transforms to clay and overtime it will crumble due to the weakness of clay
Down
- 1. When water freezes into ice and expands overtime and sugar fats to push the rock apart forming new cracks
- 4. Animals that burrow in grounds loosen and break apart rocks in the soil
- 5. the process of breaking down rocks through chemical changes
- 9. A process that wears down and carry away rocks which includes breaking down rocks into smaller pieces
- 10. A process that breaks down rocks and other substances
- 12. A material that’s full of tiny connected air spaces that allow water to seep through it
