How are rocks weathered and eroded?
Erosion of land happens in a variety of different ways. Water Wind Glacier Soil Sea Water Erosion Water erosion occurs from the chemicals in the water, and the force of the flow of water in the river. There are many chemicals in the water of a river, and those chemicals can break down certain rocks, such as limestone or chalk. This eroded rock is carried down the river. Sometimes, a crack or crevice develops. When the force of the flowing river smashes into that crack, the rock can break away, and again be carried down the river. As you can see, erosion creates a load in the river. When rocks, pebbles or even boulders smack the riverbed, or side, this can cause further erosion. Also, if a boulder is stuck in an eddy, it can create a pothole in the riverbed. Rivers can wind around, but that will be looked at in the next section. Wind Erosion Wind erosion, though it may be small where you live, can take quite a toll on areas of the world covered in desert. Wind erosion is simple… light
