There is freeze thaw action which mainly occurs in very cold climates(which reach below 0 degrees celsius). What happens is water gets into the cracks in the rocks during the day and feezes at night. Since water expands when it freezes is causes the crack to get bigger and bigger. This goes on and a section of the rock breaks off.
Also there is insulation. this occurs in cliates like a desert where it is hot during the day and cold at night. The surface of the rock heats up and expands slightly during the day but cools down and cotracts slightly at night. This is repeated and layers of the rock begin to peel off like an onion.
There is also another type called salt crystallization. This occurs in dry climates where the temperature averages 26 to 28 degrees. Any salt crystals in the rocks expands to almost 300% their orignal size and will break up the rock.
Finally there is one called pressure release. During erosion rocks may be removed from on top of other rock. The rocks that were removed exerted some pressure on the rocks underneath and when they are removed the rocks expand causing cracks is the rock. These cracks can then be made larger by the other forms of weathering

∙ 13y agoAn example of Physical Weathering is plant wedging, where a plant finds its way into a rock and its roots wedge the rock apart. An example of Chemical Weathering is Acid Rain, where chemicals in the clouds caused by global warming rain down and dissolve rocks. Thousands of years of acid rain can result in discoloring and the breaking down of rocks.

What are some non examples of deposition?
Weathering I think
Can you give me some notes about weathering?
There are two types of weathering: chemical and physical. Chemical weathering is said to occur when the chemical compounds of rocks are changed. Physical weathering happens due to wind, rain, or other natural occurrences.
What are some differences of physical weathering and chemical weathering?
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
What are some examples of constant variables in science?
A constant variable is a variable that gets changed by a physical substance
What some non examples of erosion?
non-examples of erosion would be fire or anything that does not have to do with waterice and Nanon.
What type of weathering is there?
phisical weatheringchemical weatheringandBiological Weathering
Is erosion chemical weathering?
No. Erosion usually involves the transportation of material from one place to another place. Chemical weathering involves the reaction of natural Earth materials with acidic fluids, causing dissolution.
What best describes erosion?
A weathering action changes a solid or semi-solid natural material. Most weathering actions are physical, such as wind and friction. Some is a physical force, such as earthquake and landslides that expose rock to weathering processes. Some is chemical, such as the deterioration caused by acid rains.
What are some physical changes that occur in nature?
Snow melting, laundry drying, movement of a tree in the wind
What are some secondary landforms?
A Secondary landform- is a landform created by the erosion and weathering by water, wind, and ice. Some examples are alluvial fans, floodplains, and deltas
What are the cause and effect of the weathering and erosion?
what are some causes and effects of weathering
Ways to prevent weathering and erosion?
Some of the ways you can prevent weathering and erosion is to cover it with a sealant like paint or epoxy or to just cover it with a sheet
What are some Physical weathering examples?
frost heaves, frost wedges, plant roots, and friction and repeated impact
A venn diagram for weathering and erosion?
Weathering is the breaking down of rock and erosion carries it away. Both of them contribute in some way to the formation of new soil.
What are some non examples of?
What are some non examples of weathering are everything that has to do with no rocks
How was the canyon create?
the grand canyon was made by weathering and erosion <3 :D i answered some of yalls questions now answer mine what effected the grand canyon the most weathering or erosion and how did weathering and erosion effect the grand canyon? plzz answer plzzzzzzzzzz thank u <3
What are some examples of weathering around the house?
Weathering is the breakdown of materials without movement external movement. not to be confused with erosion which relies on a current of water or air to wear away rock for example. Spilling wine on a marble surface is an example of chemical weathering as the wine will dissolve some of the surface. A physical example could be a metal fire guard weakening at it's welded joints due to repeated heating and cooling which causes thermal expansion and contraction of the structure.
