5 physical weathering agents
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.
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.
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.
this is one of my science problems so please help me on this

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 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.
the main agents of physical weathering would be hail, snow, sleet, and rain (sometimes temp.)
physical
the primary agents of weathering are water, ice, and gases in the atmosphere
Wind and water are agents of erosion
There are so many agents of chemical weathering. The two main agents that cause chemical weathering are acid rain and carbon dioxide.
