This type of weathering changes the mineral makeup of the rock
The loose, weathered material on the Earth's surface is called

This depends on the type of rock and the climate
The process of restoring an area of land to a more natural, productive state

These contribute to most of the organic remains in humus
This forms when pollutants combine with water vapor in the clouds
