What occurs during the weathering process?
There are 2 main processes of weathering, mechanical weathering and chemical weathering. In both processes the rocks are broken down. In the mechanical weathering process the rocks are simply made smaller. they are the same composition, just smaller pieces. In the process of chemical weathering the minerals in the rocks undergo a chemical change, they break down. This break down of minerals make them easier to erode. But, erosion is a different question.
Compare and contrast chemical weathering and mechanical weathering?
Mechanical weathering is taking a big rock and breaking it down to small rocks by releasing pressure, freezing and thawing (water and ice), animal action, plant growth and abrasion. Chemical weathering is when a rock loses it shape but STILL IS MADE OF THE SAME METRICAL. Chemical weathering uses water, oxygen, carbon dioxide, living organism, and acid rain.
Are cracks in a sidewalk next to a tree mechanical weathering or chemical weathering?
tree is grown by the person who is planting it therfore its made by human therefor its mechanical energy tree is grown by the person who is planting it therfore its made by human therefor its mechanical energy
Is weathering a type of erosion?
Yes! Erosion is a type of Mechanical Weathering. Erosion made the Grand Canyon, and other landforms like it.
What are some landforms made by chemical weathering?
grand cannon
Is erosion a type of physical weathering?
Yes! Erosion is a type of Mechanical Weathering. Erosion made the Grand Canyon, and other landforms like it.
Rocks being made smooth by tumbling across a stream bed is an example of?
Mechanical weathering.
Rapid chemical weathering can be caused by?
Rapid chemical weathering can be caused by acid rain. It is a type of rainfall that is made acidic due to atmospheric pollution.
Tell how snowdrifts and sand dunes are formed in similar ways. Then describe differences in how they are formed.?
Similar: Both are formed by wind. Different: Sand dunes are formed by deposition. Snowdrifts are formed by weathering. ++ They are both formed by deposition of a granular material by the wind. Weathering is totally different - it is the breakdown of rock (or other materials) by the weather, biological agents, etc. - though sand is a product of the weathering of rock.
Are chemical sedimentary rocks made of the same minerals?
No. Chemical weathering results in a change of the chemistry of the rock and the minerals therein.
Is clay a manmade resource?
No, clay is natural. It is typically made by the gradual chemical weathering of rocks.
What item made by humans that can be broken down by the agents of physical and chemical weathering?
Plants and animals and ice and frost
