What are the six major causes of mechanical weathering?
Mechanical weathering - Disintegration - breaks down into smaller pieces, no new substance. Frost Action, Abrasion, Gravity, Organic Activity, Wetting and Drying, and Joint Sheeting are the six major causes of mechanical weathering.
What type of weathering involves the decomposition of rock as minerals react with substances such as oxgenwater and acids?
Hydrolisis,freeze-thaw, chemical weathering, wetting and drying, etc
The most important mechanical weathering process?
Alternating wetting and drying, causing continuous heating and cooling of rock surfaces, due to change in weather conditions by rainfall and sunshine periods, which leads to uneven expansion within rock layers. This eventually results in cracking and peeling off of rock surfaces (exfolliation).
What is wetting and drying in geology?
Tropical Wet and dry is a place that is hot all year with rainy and dry seasons. It is grassland with some trees. It has animals like giraffes Lions and Zebras! Like the Savanna!! :)
How do freezing thawing wetting and drying contribute to soil creep?
Freezing/Thawing - Water in the soil freezing creates ice crystals that push the soil particles outwards, causing what is called "heave." When the ice crystals thaw, the soil flows don the slope due to gravity. Wetting/Drying - Heavy rainfall causes an increase to the moisture in the soil, which increases the volume and weight of the soil. This allows the soil to move down the slope under the influence of gravity. When the soil, especially clay, dries out, the soil contracts.

Which type of weathering occurs along ocean cliffs?
The type of weathering that occurs along ocean cliffs is mainly mechanical weathering, caused by processes such as waves crashing against the rocks, causing them to break apart and erode over time. Chemical weathering can also occur due to the saltwater and other chemical reactions taking place along the cliff face.
How can a river both cause a chemical and physical weathering?
Water is a major component in weathering process. Its essential for all forms of disintegration either Mechanical/Physical, Biological or Chemical. Water aids in physical weathering through alternating wetting and drying of rocks thereby leading to breaking down of the rock. It helps in chemical weathering through dissolution of chemicals in rocks such as limestone. Water is a cause of both chemical and physical weathering.
What is subaerial weathering?
It is where the effects of the weather have an impact of the coast/land. Physical/mechanical processes include: freeze-thaw, thermal expansion, salt crystalisation and wetting and drying. Chemical processes include: hydration, hydrolysis, oxidation, and carbonation. Biological weathering is done by animals, plants, and humic acid. All these processes need organic material present to occur, whether it is living or dead.

What is wetting and drying in science?
Wetting: adding a liquid to a solid or gaseous material Drying: deleting a liquid from a solid or gaseous material
What are examples of wetting and drying?
Wetting: humidification of conditioned air, humidification of clothes during a rain, etc. Drying: deleting water from humid sand, deleting water from humid dishes, etc.
What is the vocabulary word for constant swelling and shrinking makes rocks crack?
Wetting and drying. (: -Isis
What is the driving force behind weathering deposition and erosion?
Temperature Change is the driving force behind Weathering by Exfoliation. Continuous alternation of wetting and drying of rock masses results to an uneven expansion and contraction of their surface, as a result of this, an heaving and sagging mechanism is put in place and this eventually results to sheeting of the rock surface, which latter falls off.
What keeps the bodies organs from drying out and mechanical damage?
integumentary
Is drying hair a chemical or physical?
The drying itself is (always) a physical change.
