What is weathering explain it​

Answer 1

Answer:

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. ... Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering

Answer 2

$\huge{ \text{ \underline{ \underline{ \red{✿Answer}}}}}$

The scenes of the world are continuously mutating. Sun, rain, frost, and wind are breaking down even the most solid of the rocks into smaller bits before they are taken away. This process is termed as weathering. The action of the elements of climate and weather, animals, and plants on the land surfaces to break them down biologically, chemically, and physically is called weathering. It is the breakdown and decay of rocks in situ. It can be a very elongated slow procedure, taking hundreds of years. However, weathering can also be rapid, such as the damage to pavements or roads after a cold, frosty winter.

Types of Weathering

Weathering is the initial step in soil creation. Weathering happens in four different manners: These include chemical weathering, physical weathering, biological weathering, and mechanical weathering. The three major ways weathering happens include chemical, and mechanical weathering which are explained below.

Chemical Weathering

Chemical weathering is when chemicals in rain and moving water react with rocks and minerals to change or weaken them in some way. Chemical weathering always causes some type of chemical reaction within the rock or mineral itself. Expand your knowledge of the breaking down of rocks and soil through examples of erosion.

Mechanical Weathering

Rocks are also fragmented by mechanical force. This procedure is called mechanical weathering. Because of the frequent variations in temperature, rocks begin to contract and expand. This action results in the breakdown of rocks. It is also caused by the roots of plants. They are growing through the cracks in the rocks and cracks the rocks apart. Chemical and mechanical weathering work together to break down rocks. Often, mechanical cracks and water seep into the rock and weather it chemically.
