Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.

What do you mean by weathering class 8?
Answer. Weathering refers to the breaking up and decay of exposed rocks. This breaking up and decay are caused by temperature fluctuations between too high and too low, frost action, plants, animals, and even human activity. Weathering is the major process involved in the formation of soil.
What is the difference between block disintegration and exfoliation?
Block disintegration is caused by the heat and frost action, arid regions experienced high variation of day and night temperature which causes cracks in the rocks due to freeze and thaw action. Exfoliation is otherwise known as onion weathering which means peeling the rocks due to the combined action of heat and wind.
