what is the difference between weathering mass wasting and erosion?
528009
Weathering is the physical disintegration or chemical alteration of rocks at or near the Earth's surface. Erosion is the physical removal and transportation of weathered material by water, wind, ice, or gravity. Mass wasting is the transfer or movement of rock or soil down slope primarily by gravity.

Weathering processes crack, wear away, and weaken rocks. Over time, it may cause large changes to the landscape. Physical and chemical weathering degrade rocks in different ways. While physical weathering breaks down a rock's physical structure, chemical weathering alters a rock's chemical composition.

The most common mass-wasting types are falls, rotational and translational slides, flows, and creep. Falls are abrupt rock movements that detach from steep slopes or cliffs. Rocks separate along existing natural breaks such as fractures or bedding planes. Movement occurs as free-falling, bouncing, and rolling.

While weathering and erosion are similar processes, they are not synonymous. Weathering involves the breakdown of rocks and minerals on Earth, whereas erosion involves the removal of soil and rock materials.

Weathering is the action of breaking down existing rocks into smaller pieces (soil). ... Deposition is the end of the cycle, where soil particles are placed after movement, typically at the bottom of a hill, at a windbreak, or at the bottom/edge of a water body.

Landslide:Usually it happens in the terrain or slope regions. Where large movement of rock, debris, land happens down the slope. ... Soil erosion is occur due to deforestation while landslide occur due to mining,incessant rain(sedimentary rock). Soil erosion losses fertility whereas landslide vanish virgin vegetation.

Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes. ... Rocks are broken into smaller pieces by abrasion or pressure. Landforms are worn down by the agents of mechanical weathering.

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.

weathering is the wearing away of rocks. erosion is the movement of the broken pieces away from the site of weathering.

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!

Wind erosion is occurred when pieces of the earth are worn away by the strong winds. It occurs in dry bare areas when wind blows and moves the dirt around. ... Water erosion is the process where the piece of earth is worn away by water. It occurs at river banks or streams.

1 Answer. Weathering and erosion break down surface structures. Deposition builds them up.

weathering breaks down parent material into loose regolith or dissolved ions. water or wind transport the weathering products and deposit them in basins to form sedimentary rocks.

Weathering is when rocks are broken down (chemically or mechanically) and erosion is when sediment is carried away. What is the difference between erosion and deposition? Deposition is when the sediment settles out of the water , wind or ice that is carrying it. You just studied 32 terms!

Climate is based on temperature and precipitation. Mass wasting is prone in the spring-time when snow melt, water saturation, and runoff is greatest. Also the type of climate will help determine the type of mass wasting. Humid climates tend to have slides, where water-saturated slopes fail and fall.

These processes initiate a change in a rock's appearance or composition. However, physical weathering changes the rock's appearance through physical changes like abrasion; while in chemical weathering, chemical reactions that happen in the environment change the rock's appearance and composition.
