EVERYDAY SCIENCE

Detailed explanation-1: -Erosion occurs when natural agents, such as wind, water, or ice, transport the loosened soil and broken-down rock away. Erosion prevents earthen materials from building up in the place the materials formed. In most cases, erosion is a slow process that occurs inconspicuously over long periods of time.

Detailed explanation-2: -Waves, wind, water, and ice shape and reshape the Earth’s land surface by eroding rock and solid in some areas and depositing them in other areas, sometimes in seasonal layers. Rock is composed of different combinations of minerals. Smaller rocks come from the breakage and weathering of bedrock and larger rocks.

Detailed explanation-3: -Volcanoes, earthquakes, and tsunamis are all rapid changes and erosion and weathering are all slow changes.

Detailed explanation-4: -Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth’s surface much more quickly. These include volcanic eruptions, earthquakes, and landslides.

Detailed explanation-5: -Gravity and erosion are major factors in changing the shape of the surface of Earth.
