The process of leaves decaying in the forest is considered to be chemical weathering. During decay, organic matter in the leaves breaks down and releases minerals into the soil, altering its composition. This chemical process aids in the weathering of rocks and contributes to soil formation.
No, leaves decaying in the forest is not considered mechanical weathering. Mechanical weathering involves physical processes like abrasion or freeze-thaw cycles that break down rocks into smaller pieces. Decaying leaves contribute to chemical weathering as they release acids that can break down minerals in the soil.
The agent in mechanical weathering where the sun or forest fire causes rocks to crack is thermal expansion and contraction. This process occurs when rocks are exposed to heat from the sun or a fire, causing them to expand and contract at different rates, leading to cracks and eventual breakdown.
A bare mountain peak may be exposed to freeze/ thaw cycles, harsh sunlight, surface erosion by wind blown and water carried particles, and chemical weathering from acid rain. Bedrock under soil is not exposed to most weathering forces.
Chemical weathering occurs more rapidly in a rainforest compared to a desert because of the higher temperatures, abundant moisture, and presence of organic acids in the soil of rainforests. These factors facilitate faster chemical reactions that break down rocks and minerals into smaller particles. In contrast, deserts have lower moisture levels and fewer organic acids, slowing down the chemical weathering processes.
Thermal weathering occurs when rocks are exposed to extreme temperature changes, such as those from forest fires. The rapid heating and cooling of rocks causes them to expand and contract, eventually leading to the splitting and fracturing of the rocks.

Decaying leaves contribute to chemical weathering as they release acids that can break down minerals in the soil.
The rates of mechanical weathering does not affect anything since the chemical properties remain unchanged. Only chemical weathering affects the chemical properties of an object.
In the Congolese rainforest, the rates of chemical weathering are likely higher due to the warm and wet climate, which accelerates chemical reactions that break down rocks. In contrast, in the Siberian steppes, mechanical weathering rates might be higher due to freezing and thawing cycles that physically break down rocks through processes like frost wedging.

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.

Decaying is a slow process. It can take years.
