Natural agents of physical weathering: Rain, sand (driven by the wind), sunlight, the freeze/thaw cycle. Man-made agents of physical weathering: Acid rain.
the main agents of physical weathering would be hail, snow, sleet, and rain (sometimes temp.)
It is important to not that weathering does not involve movement of rock like in the case of erosion. The five agents of weathering are ice, water, waves, gravity and snow.
Well, three things that cause weathering are plant roots, ice, and physical stress.
Well its complicated answer
The agents of weathering include water, wind, sun, ice, frost, and plants and animals. All these different agents work on rocks and make changes to them over years.
Physical weathering breaks big rocks into little rocks and increases the surface area exposed to chemical agents, such as carbonic acid. The more the surface area, the faster the weathering.
The agents of "weathering" is both the agents of the physical and the chemical weathering combined. Agents of physical weathering can be: wind, water, sun, ice, gravity, rain, etc. Agents of chemical weathering may be: acid from roots, acid rain, oxidation/reduction (rusting), carbon dioxide, etc. They are the same because both physical and chemical weathering lead to erosion of rocks. In other words, both help rocks break down into smaller pieces. They are also the same because both physical and chemical weathering can occur with the same agent. For example, TREES. The roots of trees release acid to break down rocks (chemical weathering) while the roots of trees also grow into the cracks of rocks and help break them apart (physical weathering). Note that weathering is just the beginning process of erosion. Erosion is when stuff actually breaks down into smaller pieces.
this is one of my science problems so please help me on this
Yes, because there are two types of weathering, chemical and physical weathering. Chemical weathering can cause erosion through its five agents.
The physical weathering agents are basically the water and wind. But the rocks decay mostly because of wind. Wind blows continuously for ages and the rocks that stand in the way get decayed in the long run.
