Weathering is the process of disintegration of rock from physical, chemical, and biological stresses.
Influence factors: temperature and moisture (climate).
As rock disintegrates, it becomes more susceptible to further processes due to the increase in exposed surface area.
Types of Weathering
Physical weathering is known as mechanical weathering, involving disintegration of rock by physical forces is referred to as physical weathering.
For example, change in temperature, abrasion, frost action and salt crystal growth are some of these physical factors.
Example: Gand Canyon
In the interest of changing the composition of rocks, chemical weathering involves the interaction of rock with chemicals. Water and minerals engage in this process, leading to an array of chemical reactions which modify the rocks.
For example the clearest representation of chemical weathering is the rusting of iron because of oxidation.
Biological Weathering is plants that break up rocks with their roots or root exudates are referred to as biological weathering.
For instance, a plant may grow in a gap in a rock and cause the crack to widen while its roots grow. Another example: A rabbit may also burrow into a crack in a rock, making it bigger and splitting the rock.
The process of weathering is very important in shaping the world we live in;

The animation video can be an interesting and easy way to provide very precise information to a younger audience. However the animation can only touch a surface of the weathering process in the real world. The way of conveying information can be limited to a small audience.
