Reading passage
The weather can change the Earth in many ways. If it rains too much, it can flood. If there is too much water in the rivers and streams, water can flow onto the land.
A drought happens if there is no rain. The land gets very dry and sometimes it cracks.
Weathering can also change the land. Weathering happens when rocks break and change.
Erosion happens when wind or water moves rocks and dirt. To prevent erosion, you can dig the earth and plant a tree.
The land can change quickly or slowly. The shape of the land is always changing. Rain, wind and ice can all make the land change.
