Mechanical weathering occurs due to situations such as wind, rain, ice or lava that carry away materials. Mechanical weathering is a set of geological phenomena that causes rocks, soil and minerals to break down without ... More » Science Earth Science Geology

The primary difference between weathering and erosion is that weathering refers to the erosion of natural substances without movement, while erosion includes movement of particles and surface materials. Weathering and er... More »

Some different types of physical weathering are abrasion, salt crystallization, insolation, frost action and wetting and drying. Physical weathering is a geological process in which over time rock or mineral break apart.... More »

Plants and animals become agents of mechanical weathering when their growth, activities or movements expose rocks to the weathering actions of wind, rain and ice. The roots of plants, particularly large trees, can shift ... More »

Weathering occurs when materials are eroded or broken down by natural means, such as ice, water and wind. Acid, plants and animals can also cause weathering. More »

Mechanical weathering may occur due to thermal fractioning, frost wedging, hydration shattering, exfoliation and abrasion. During mechanical weathering, external forces cause solid rock material to break into smaller sed... More »

Granite changes into sandstone by means of weathering and erosion. Through the passage of time, fragments of granite are broken down into smaller pieces, or sediments, which are transported and deposited at the bottom of... More »
