1. Weathering refers to the process of breaking down rocks and minerals on the Earth's surface. It occurs due to various factors such as changes in temperature, moisture, and chemical reactions.
Erosion is the movement and transportation of weathered materials such as sediments, soil, and rock fragments by agents like wind, water, ice, or gravity. It is the process by which soil, rock, and minerals are removed from their original location.
Deposition is the process in which eroded materials are deposited or settled in a new location. This typically occurs when the eroding force loses its energy and can no longer transport the sediment.
2. Compaction is a geological process that occurs during sediment deposition. It involves the reduction of pore spaces and the squeezing together of particles within a sediment or sedimentary rock. Compaction occurs due to the weight of overlying sediments, which forces the sediments closer together, reducing the volume of pore spaces. This process results in the sediment becoming more tightly packed and consolidated, leading to the formation of sedimentary rocks such as sandstone, shale, or limestone. Compaction is crucial in the creation of sedimentary rock layers.
