why erosion is exogenic geological processes?
473460
Exogenic processes are those driven by exogenic forces that primarily derive their energy from solar radiation. For instance, soil erosion is caused by the force of wind acting on bare ground. ... Soil is detached when wind blows over an erodible surface. Water and glacial erosion are other examples of exogenic processes.

What is the difference between erosion and deposition? Erosion is the removal of sediments by gravity, water, ice, or wind; deposition is the accumulation of sediments in low-lying areas due to the action of gravity, water, ice, or wind. You just studied 16 terms!

Four basic processes are involved in the formation of a clastic sedimentary rock: weathering (erosion)caused mainly by friction of waves, transportation where the sediment is carried along by a current, deposition and compaction where the sediment is squashed together to form a rock of this kind.

Geological hazards occur because of geological processes such as movement in the tectonic plates and volcanic activity. These events include earthquakes, volcanic eruptions, and landslides. ... Meteorological hazards include extreme temperatures, hurricanes, tornadoes, droughts, and severe storms.

Some landforms created by erosion are platforms, arches, and sea stacks. Transported sand will eventually be deposited on beaches, spits, or barrier islands.

Wind erodes the Earth's surface by removal of loose, fine-grained particles by turbulent eddy actions and it is called Deflation. Regions which experience intense and sustained erosion are called deflation zones. Abrasion refers to grinding of the rock surfaces with particles captured in the air.

The forces of glacial and water erosion and deposition Glacial deposition is always drift, glaciers are powerful enough to carry tiny or large pieces of rock debris. Water erosion is the seperation of pieces of soil by the forces of water. Water deposition occurs when water deposits tiny sediments and particles.

Erosion is distinct from weathering, in which chemical and physical processes simply break down larger pieces of rock into smaller ones. In erosion, the portions of Earth affected are moved from their original location by forces exerted by gravity, wind, flowing water or some combination.

The primary difference between weathering and erosion is that weathering occurs in place whereas erosion involves movement to a new location. Both are caused by similar factors of wind, water, ice, temperature, and even biological action. They can also occur together.

Weathering is the physical or chemical breakdown or change of objects due to weather conditions. It occurs mainly through the action of wind, water, and temperature on rocks and soil. ... Erosion is the removal and transport of surface materials (soil, rocks, mud, etc.) through the actions of wind, water, and ice.

normal erosion. [′nȯr·məl i′rō·zhən] (geology) Erosion effected by prevailing agencies of the natural environment, including running water, rain, wind, waves, and organic weathering. Also known as geologic erosion.

The agents of erosion are ice, water, wind, waves and gravity. The degree to which erosion occurs depends on the slope of the land, amount of rain or snow, wind and looseness of the rock and soil.

Terms in this set (16) Erosion is the removal of weathered pieces of rock to another place. What is the difference between mechanical and chemical weathering? Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.

Farming. Agriculture is probably the most significant activity that accelerates soil erosion because of the amount of land that is farmed and how much farming practices disturb the ground (Figure 1). Farmers remove native vegetation and then plow the land to plant new seeds.

Forces like wind and water break down rocks through the processes of weathering and erosion. Weathering is the process that breaks down rocks. Many things cause weathering, including climate changes. Erosion breaks rocks down further and then moves them.

Explanation: Erosion can occur naturally by wind, water, and gravity. ... Other effects of erosion include increased flooding, increased sedimentation in rivers and streams, loss of soil nutrients' and soil degradation, and, in extreme cases, desertification.
