The changing surface of the Earth

The changing surface of the Earth

The Earth's surface is changing all the time, these changes are caused by wind, wind and ice and are so gradual that we fail to notice them. Tiny rivulets flowing down from the top of the mountains join with others and soon turned into fast flowing rivers. These rivuletes and rivers varry away with them, rocks and the upper layers of soil, some even cut into the sides of mountains that they flow through. The rock and soil carried away is then deposited in the deltas and the seas. Rain water seeps into the ground and cuts away under the surface thus forming underground tunnels. On the desert-front strong gusts o f wind form sand dunes and constantly blow sand onto rocky surfaces thus gradually cutting them into new shapes. On the higher altitudes water seeps into crackes in rocks and freezes. As it freezes, it expands, thus splitting the rocks.
