Question

write essay on weathering and erosion​

Answer 1

Answer:

Weathering is the breaking down of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms. Weathering occurs in situ (on site, with little or no movement), and should not be confused with erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity.Weathering processes are divided into physical and chemical weathering. Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils. Water is the principal agent behind both physical and chemical weathering, though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. Chemical weathering by biological action is also known as biological weathering.

The materials left over after the rock breaks down combine with organic material to create soil. Many of Earth's landforms and landscapes are the result of weathering processes combined with erosion and re-deposition. Weathering is a crucial part of the rock cycle, and sedimentary rock, formed from the weathering products of older rock, covers 66% of the Earth's continents and much of its ocean floor

Answer 2

Answer:

Weathering and erosion are two processes that sort of shape Earth’s ground and rocks. Weathering is either a mechanical or chemical process that breaks down or shapes rocks, while erosion transports the leftovers of weathering, away. Understanding these processes helps us understand the way lakes, rivers, mountains, shorelines, canyons, and all sorts of other things were formed. For example the Grand Canyon was formed by erosion created from the Colorado River. It is very important to understand how these forces occur to understand the subject completely.
