Give geographical reason: Many times, rocks break.

Rocks break because-

1. Rocks which are exposed are affected by the climate of that region in various ways. 

2. Rocks can break because of water, pressure, heat, etc. in various ways. 

3. Those rocks which have joints or layers, break easily than rocks which are homogeneous. 

4. The rocks which have vertical strata are easily loosened and break, due to changes in temperature, water, wind or frost action. 

5. If there are larger grains in the rocks, there is ample space in the rocks for water to enter and they get weathered easily and break. 

6. Some rocks are very hard and resistant to chemical weathering but they are easily fractured by physical weathering. 

7. Generally, sedimentary rocks break easily than igneous rocks and metamorphic rocks.
