what kind of damage can a drought
a drought can destroy farmers crops

flooding,fire
how does water break rocks
in nature water flows into little cracks and openings in rocks. when winter comes the water may freeze because of low temperature and break off pieces of rock.

yes, when snow falls on a steep slope in the mountains, it forms a layer. As more snow falls during the winter, new layers are formed. Sometimes the new layer slides down the slope into the valley. We call this an avalanche.
