L1 : WEATHERING Flashcards
what is weathering?
Weathering is the deterioration of rocks
_______ is the deterioration of rocks
weathering
what are the 3 kinds of weathering?
physical, chemical and biological weathering
also called mechanical weathering and a process that causes the disintegration of rocks without chemical change.
physical weathering
it involves the interaction of rock with mineral solutions (chemicals) to change the composition of rocks.
chemical weathering
is caused by the movements of plants and animals.
biological weathering
3 types of physical weathering
Abrasion
Freeze-thaw
Exfoliation
Rocks and sediment grinding against each other wear away surfaces. It happens as wind and water rush over rocks. What type of physical weathering is this?
Abrasion
Type of Physical Weathering that occurs when water seeps into cracks in rocks or the pores between soil particles and freezes.
Freeze Thaw
A form of mechanical weathering in which curved plates of rock are stripped from rock below.
Exfoliation
5 types of chemical weathering
Carbonation
Acidification
Hydrolysis
Hydration
oxidation
It is the type of chemical weathering that is the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves.
Carbonation
It is the type of chemical weathering that is caused by multiple forces including chemical weathering of soils.
Acidification
It is the type of chemical weathering :
In the process of _____, a new solution (a mixture of two or more substances) is formed as chemicals in rock interact with water.
Hydrolysis
________ is a form of chemical weathering in which the chemical bonds of the mineral are changed as it interacts with water.
Hydration
