The breaking down or dissolving of rocks and minerals on Earths surface.

• Transformation

• Weathering

• Wheathering

• Erosion

These processes are more rapid in desert and in the cold environment on high mountains and closer to the poles.

• Chemical Weathering

• Physical Weathering

• Biological Weathering

Is a type of weathering which caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts.

• Physical Weathering

• Chemical Weathering

• Biological Weathering

A type of weathering that causes the weakening and subsequent disintegration of rock by plants, animals and microbes.

For (a)   action to take place, intense cold is not needed. What is needed is for the temperature to fall below and rise above 0°C many times to produce many cycles

Is a form of physical (mechanical) weathering in which curved plates of rock are stripped from rock below.

(a)  

(a)   is the process that happens when the rock type in an area is limestone.

(a)   is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions.
