factors that affect the rate of weathering
completion: write the missing word or words on the space before each number. for items 13 - 20

1. ___ speeds up chemical weathering.
2. weathering happens ___ in hot, wet (humid) climates.
3. weathering occurs very slowly in _ and _ climates.
4. without ______ changes, ice wedging cannot occur
5. in very ____ and ____ areas, there is little weathering.
6. most weathering occurs on ____________ of rocks and minerals
7. the ______ surface area a rock has, the quicker it will weather.
8. some minerals resist weathering. ____________ is a mineral that weathers slowly.

rocks made up of minerals such as feldspar, ____, and iron, weather more quickly.

Explanation:

1. Heat speeds up chemical - reactions involved in weathering.
2. In hot, wet climates, conditions are favorable for weathering processes, so it happens faster.
3. Cold and dry climates lack the necessary elements like water and warmth for rapid weathering.
4. Ice - wedging requires temperature changes to cause water to freeze and expand.
5. In very cold and dry areas, there is little water and energy for weathering to occur.
6. Weathering acts on the surface of rocks and minerals.
7. A larger surface area exposes more material to weathering agents.
8. Quartz is a well - known mineral that weathers slowly, while minerals like mica weather more quickly.

3. cold; dry
4. temperature
5. cold; dry
