What Are two kind of weathering?
The 2 kinds of weathering are the Mechanical or Physical Weathering and the Mechanical Weathering.
What kind of weathering does not alter the chemical composition of the rock?
mechanical weathering (by wind or water or perhaps tenacious plant roots or human activities)
What kind of weathering causes iron?
physical weathering
What is another name for mechanical weathering?
One kind of Mechanical Weathering is called ice wedging.
What is is the common kind of mechanical weathering?
frost wedging ?
Is chemical weathering when rocks break apart by wind frost and roots?
No. That is mechanical weathering. Weathering by sand or other matter carried in the wind is a special kind of mechanical weathering called aolean weathering. Weathering by acid rain is an example of chemial weathering. Limestone is particularly subject to this. Illegibility of tombstones in old garveyards provide a good illustration of this.
What are the main types of each kind of weathering?
chemical and mechanical
What kind of weathering causes repeated expanding due to the heat and contracting due to cold strains the rocks and causes them to crack?
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
What kind of weathering causes mineral composition of rocks to change?
Chemical weathering
What kind of weathering causes mineral composition of rock to change?
Chemical weathering
What kind of weathering happens when ice forms in cracks in a rock?
Freeze-thaw weathering occurs when water seeps into cracks in rocks, freezes, expands, and creates pressure that can cause the rock to fracture or break apart. This process is common in regions with climates that experience freezing temperatures.
What kind of weathering creates potholes?
Freeze-thaw weathering is a common process that creates potholes. Water seeps into cracks in the road, freezes during cold weather, expands, and weakens the pavement material. This cycle of freezing and thawing causes the road surface to break up, leading to the formation of potholes.
