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
What occurs during the weathering process?
Weathering is the breakdown of rocks, minerals, and soils into smaller particles through physical, chemical, or biological processes. This can involve physical processes like freeze-thaw cycles or chemical processes like oxidation. Weathering plays a key role in shaping the Earth's surface over time.
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 types of weathering made stone mountain?
Stone Mountain was primarily created through mechanical weathering processes such as freeze-thaw cycles and exfoliation, where outer layers of rock peel off due to pressure release. Chemical weathering may also have played a role in contributing to its sculpted shape.
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.
What is the difference between siliciclastic and chemical or biochemical sedimentary rocks?
Siliciclastic sedimentary rocks are made up of particles eroded from pre-existing rocks and transported by water, wind or ice before being deposited and lithified. Chemical or biochemical sedimentary rocks are formed from the precipitation of minerals dissolved in water or by the accumulation of organic matter, such as shells or coral fragments. The main difference lies in the origin of the sediment grains, with siliciclastic rocks being composed of particles derived from mechanical weathering and chemical or biochemical rocks forming through chemical processes.
Rapid chemical weathering can be caused by?
Rapid chemical weathering can be caused by factors such as increased rainfall, higher temperatures, and the presence of acidic substances. These conditions can accelerate the breakdown of rocks and minerals, leading to faster weathering processes.
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.
Rocks being made smooth by tumbling across a stream bed is an example of?
Mechanical weathering, specifically abrasion. The rocks are physically broken down and worn away as they rub against each other and the stream bed, creating smooth, rounded surfaces.
