The rock cycle consists of patterns that change elements on the Earth's surface. Weathering and erosion are two processes in the rock cycle. What role do weathering and erosion play in the rock cycle, and what type of rock is made from these processes?

Answer 1

Weathering and erosion play crucial roles in the rock cycle by breaking down existing rocks and transporting the resulting sediments.

Weathering is the process by which rocks are broken down into smaller particles due to various factors including mechanical forces (like freezing and thawing), chemical reactions (such as oxidation, hydrolysis), and biological activity (like root growth). This results in the formation of sediment, which can include particles of minerals, rock fragments, and organic materials.

Erosion involves the removal and transportation of these weathered materials by agents such as water, wind, ice, or gravity. Once transported, these sediments can accumulate in new locations, such as riverbeds, lakes, or ocean floors.

Through the processes of weathering and erosion, sedimentary rocks are formed. These rocks are created when sediments are compacted and cemented together over time. Common examples of sedimentary rocks include sandstone, limestone, and shale.

In summary, weathering and erosion contribute to the rock cycle by breaking down existing rocks into sediments and transporting them, which eventually leads to the formation of sedimentary rocks.
