Weathering of rocks occur on the outer surface.
The most important weathering agent is water.Water dissolve soluble materials transforming rocks.
Weathering takes place the most in regions with high humidity and precipitation, such as tropical rainforests or coastal areas. This is because moisture accelerates chemical weathering processes by promoting the breakdown of rocks and minerals.

compacting and cementing
Weathering of rocks takes place through mechanical or physical weathering, where rocks break down into smaller pieces due to factors like temperature changes, frost action, and pressure. Chemical weathering is another process where rocks are broken down through chemical reactions such as oxidation or dissolution caused by exposure to water, air, or acids. Over time, these processes can weaken rocks and cause them to disintegrate into smaller particles.
Weathering does not necessarily have to take place before erosion. While weathering is the breakdown of rocks into smaller particles, erosion is the process of transporting these particles to a new location. Weathering can occur simultaneously with erosion or even after erosion has started.
Chemical weathering is most likely to occur in areas with high temperatures, abundant moisture, and exposure to oxygen. This is because these environmental conditions accelerate chemical reactions that break down minerals in rocks. Areas with tropical climates or high levels of rainfall are prime locations for chemical weathering to take place.
Erosion and weathering occur on the Earth's outermost layer, called the crust. This is where the processes of physical and chemical breakdown of rocks and landforms take place, leading to the reshaping of the Earth's surface over time.
physical weathering refers to weathering that occurs because of brute force, while chemical weathering refers to weathering that take place because change in the molecular composition of the substance
Immediately, nothing. However over long periods of time, weathering can take place. This is where the wind patterns begin to shape and carve the rock.
The rate at which weathering and erosion occur on rocks can vary greatly depending on factors such as rock type, climate, and the presence of organisms. Weathering and erosion can range from taking thousands to millions of years to significantly alter or break down rocks.
