Weathering is a process by which rocks and minerals are gradually broken down into smaller and smaller particles.
Weathering of rocks is caused by chemical and mechanical means. Slightly acidic rainwater can react with rock surfaces, dissolving them over time. Rocks can also be affected by organic sources of chemical reactants. Heat from the sun can cause differences in temperature between the surface and the interior of a rock which can cause a loosening of the surface called exfoliation. Liquid water penetrates cracks in the rocks surface where it can freeze and expand, opening up the cracks for further attack in tandem with acidic rainwater. Plant root growth can also cause cracks to further expand, making them more vulnerable to frost expansion and chemical attack. Underlying rock which is exposed due to erosion of the overlying rock becomes free of the pressure it was previously exposed to, causing the rock to expand and break apart. Other means of weathering include the expansion of crystallizing salts that have been taken in by a rock surface, expansion due to the absorption of water, and hydraulic action from crashing waves on seashore rock formations. Technically, erosion is a type of weathering. Weathering affects both color and size. It includes the affects of wind, rain, sunlight, freezing and heat. Erosion is water and wind wearing away objects like a like mountains and earth. Weathering is general wearing away from rain and wind, like jagged mountains gradually wear down to smoother and lower hills.
Weathering is when the rocks get broken down.
Erosion is when the little rocks get moved around.

In what order do deposition weathering and erosion occur?
first the weathering happens which causes an erosion which makes deposition.
What is the process that break down rock called?
Weathering or erosion.
How is a hurricane related to weathering erosion and deposition?
how is hurricane related to weathering
What is the weathering of the earth's surface called?
The weathering of the Earth's surface is called erosion. Erosion is the process by which soil and rock are removed and transported by wind, water, or ice.
What is the principal difference between weathering and chemical weathering?
The principal difference between weathering and chemical weathering is that weathering involves physical processes that break down rocks into smaller pieces without changing their chemical composition, while chemical weathering involves chemical reactions that alter the mineral composition of rocks.
What is the difference between weather and erosion?
the difference between weathering & erosion is quite simple weathering breaks down and erosion carries it away like a blow dryer
Is there any difference between erosion and weathering of rocks?
erosion reqiures movement and weathering doesnt
How is weathering distinct from erosion and what are the key differences between the two processes?
Weathering is the process of breaking down rocks and minerals on the Earth's surface, while erosion is the movement of these broken down materials from one place to another. The key difference between weathering and erosion is that weathering occurs in place, causing rocks to break down, while erosion involves the transportation of these weathered materials by wind, water, or ice to a different location.
What is the main different between weathering and erosion?
Weathering is a process that involves breaking up of rocks into smaller parts while erosion refers to the movement of soil from one place to another. The main difference between these two processes is that erosion takes place within a short period of time while weathering takes a longer period of time.
What thing is different from erosion and weathering?
Erosion is when..................................................................................................................................................and weathering is when......................................................................................................!
What is the different between weathering and erosion?
maybe there just differrent by how they work
What comes first weathering erosion deposition?
weathering then erosion ,then deposition
Is erosion another name for weathering?
Yes, erosion is a synonym of weathering.
Does weathering must take place before erosion?
Weathering does not necessarily have to take place before erosion. While weathering is the breakdown of rocks into smaller particles, erosion is the process of transporting these particles to a new location. Weathering can occur simultaneously with erosion or even after erosion has started.
In what order do deposition weathering and erosion occur?
first the weathering happens which causes an erosion which makes deposition.
Why is the sediment load in a river an indicator of the amount of weathering and erosion?
Because the bigger the load is, more weathering and erosion there is. The less of it means less of weathering and erosion.
What are the process that cause earths surface to wear down?
