A plant can act as an agent of mechanical weathering by simply growing next to something. The plant will rub against it and in some cases grow in any openings in the material. Tree roots can grow into the cracks in boulders and ledges, widening these cracks and ultimately contributing to the break-down of these structures. Plants also produce oxygen gas which contributes to chemical weathering through the formation of metal oxides. Tree roots also take nutrients and minerals from the soil, ultimately leaving them on top of the ground and subject to erosion forces.
No, the most important agent of chemical weathering is typically water. Water helps break down rocks through processes like hydration, hydrolysis, and oxidation. Abrasion, which is the physical wearing down of rocks by friction and impact, is an example of mechanical weathering rather than chemical weathering.
The most important weathering agent is water.Water dissolve soluble materials transforming rocks.
When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
Chemical weathering is most common in regions with warm, humid climates where water and organic acids can break down rocks over time. This process is especially prevalent in areas with abundant rainfall, such as tropical regions.
Carbon Dioxide from the atmosphere combines with water to form carbonic acid, it is a form of acid rain.

Chemical weathering.
If you drop a rock and it breaks into pieces, then that is an act of mechanical weathering.
The agent of weathering responsible for breaking rocks is mainly mechanical weathering. This process involves physical forces like wind, water, and ice that break down rocks into smaller pieces without changing their chemical composition. Examples of mechanical weathering include frost wedging, abrasion, and root pry.
mechanical weathering
No. mechanical weathering is the breaking and separating of rock or other materials. In order for mechanical weathering to occur you need water or some kind of mass movement. the only erosional agent which works with mechanical weathering are creep and solifluction, but mechanical weathering itself cannot happen because if it is too cold the frost wedging cannot happen becasue the water would freeze in contact and would not expand

Chemical weathering causes acid rain. When sulfur dioxide and nitrogen oxides are released into the atmosphere from human activities, they combine with water vapor to form sulfuric acid and nitric acid, which then fall to the earth's surface as acid rain.
Agents of chemical weathering depend on the climate and composition of the rock that is breaking down. Some Agents would include, water, oxygen, CO2, and acids. Temperature plays a significant role in chemical weathering. If it is warm and wet, the Chemical weathering process will increase. So, really it all depends.
