How do rocks get weathered?

Answer 1

A rock can be weathered by water and wind.
Rocks can be eroded by abrasion from particles carried by water, wind, or ice.

One way is wind over time can wear a rock down.

Another is water can erode something like sand into finer particles on a beach.

A third way rock can be weathered is friction against another object can wear something down over a long period of time.

Answer 2

Mechanical Weathering: This process involves physical forces that break down rocks without changing their chemical composition. Common mechanisms include temperature changes, such as freezing and thawing, which can create cracks and expand them over time. Root growth from plants can also exert pressure on rocks, causing them to break.

Chemical weathering occurs when the minerals in rocks react with substances in the environment. Water is a significant agent in this process, as it can dissolve minerals and create chemical reactions that weaken the rock's structure. For example, carbonic acid in rainwater can dissolve minerals like calcium carbonate.

Biological Weathering. Living organisms, such as lichens, mosses, and bacteria, can contribute to weathering. These organisms can produce weak acids that break down minerals and can establish themselves in cracks in the rock, furthering its breakdown.

Rocks can be weathered through abrasion, where wind, water, and ice transport particles that can erode the surface of the rock over time.

Some rocks, like iron-bearing minerals, can rust or oxidize when exposed to oxygen. This chemical reaction weakens the rock's structure and can lead to its disintegration.

Minerals within rocks can absorb water, causing them to expand and contract with changes in moisture levels. This repeated expansion and contraction can lead to the breakdown of the rock.

Weathering is a slow and continuous process, and its effects depend on the type of rock, the local climate, and other environmental factors.

Answer 3

by weather The process of weathering of the rock decreases the cohesive forces binding the mineral

grains and leads to the disintegration of bigger masses to smaller and smaller particles. Soils are

formed by the process of weathering of the parent rock.

Answer 4

Rocks can be eroded by abrasion from particles carried by

1. water,
2. wind, or
3. ice.

Rock can be weathered by friction against another object like pebbles on a beach become round and smooth over the years.

Answer 5

Rocks are weathered in a lot of ways.

river-water

wind

ice

glaciers

waves

movements inside Earth

these are some these move/break rocks

Answer 6

Rocks get weathered by water, wind, and earth which moves across them. Over time, they slowly wear away the surface.

Answer 7

They are broken into smaller pieces or particles, without a change in composition.

Answer 8

A rock can get weathered by erosion by water/rain after a really long time.For example, the Grand Canyon formed by erosion for MILLIONS of years.

Answer 9

Frost Wedging hiya kids!=)

Answer 10

by the water or the trees in the ground
