What are the two major type of weathering 2?
Answer: 2. two major type of weathering are physical and chemical weathering.
What are the 2 types of physical weathering called?
There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.
Which are the different types of weathering?
There are three types of weathering, physical, chemical and biological.
What is the best example of physical weathering?
The correct answer is (a) the cracking of rock caused by the freezing and thawing of water.
What are the 7 types of physical weathering?

What is the greatest agent of erosion?
Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.
What type of weathering is onion skin?
Spheroidal weathering is also called onion skin weathering, concentric weathering, spherical weathering, or woolsack weathering.
How are the different types of weathering different?
Types of Weathering Weathering is the initial step in soil creation. Weathering happens in four different manners: These include chemical weathering, physical weathering, biological weathering, and mechanical weathering. The three major ways weathering happens include chemical, physical, and mechanical weathering which are explained below.
How are rocks broken down in mechanical weathering?
Weathering refers to the breaking down of rocks by the conditions in their environment. Mechanical weathering occurs when rocks are broken down by the movement of other rocks, changes in temperature, the action of ice or water, or changes in the physical stress applied to the rocks.
How are carbonation and oxidation types of weathering?
Carbonation and oxidation are types of chemical weathering. Organic weathering occurs when plants and animals break down rocks. For example, plant roots working into rocks and animals digging and moving rocks are both types of organic weathering.
Which is an example of subsurface weathering and erosion?
Hydration and hydrolysis contribute to flared slope s, another dramatic example of a landscape formed by weathering and erosion. Flared slopes are concave rock formations sometimes nicknamed “wave rocks.” Their c-shape is largely a result of subsurface weathering, in which hydration and hydrolysis wear away rocks beneath the landscape’s surface.
