What happens to a rock when they are uplifted to the surface of the earth?
Pressure on them is released, which can cause pressure-release mechanical weathering. Exposure of an uplifted rock to the surface will fully expose the rock to the effects of mechanical and chemical weathering--basically a rock rot.
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
What effect does weathering have on igneous rock?
The effect of weathering is to reduce the volume of the igneous rock.
What part of a rock does weathering attack most rapidly?
Weathering tends to attack the outermost layer of a rock, known as the rock surface or rind, most rapidly. This layer is more exposed to the elements and is therefore more susceptible to weathering processes such as erosion, chemical weathering, and physical weathering.
Is ice freezing in a crack of a rock considered weathering or erosion?
Ice freezing in a crack of a rock is considered weathering.
How does the size of an expose rock affect it's rate of weathering?
it speeds up the weathering process

What property of rock remains unchanged by mechanical weathering?
Technically, they do remain unchanged. But as physical weathering of rocks progresses, it can expose the minerals in the cracks to the elements resulting in the disintegration of the rock. The mineral makeup of the rock will then change to agree with the surrounding environment.
Gravity of chemcial weathering?
Chemical weathering is the breakdown of rocks through chemical reactions. Gravity can contribute to chemical weathering by exerting pressure on rock formations, causing them to crack and fracture. This can expose a larger surface area of the rock to chemical agents like water and oxygen, accelerating the process of chemical weathering.
What are possible sources of unconformities?
Possible sources of unconformities include erosion, deposition of sediment, tectonic movement that tilts or folds rock layers, and changes in sea level that expose rock layers to weathering and erosion.
Do rocks always remain the same?
No. The rocks are constantly expose a geodynamic processes that after thousands or years finally result in the formation of others rock with different characteristics. The processes that affect a rock depend in the kind of rock and the place in the earth structure it is located. But rock in the earth surface are expose to weathering that can be produce by physical or chemical factors. The final result of the weathering is the fragmentation of the rock in particles and transportation of these particles by wind or water to a different place. In this different place the particles will participated in the formation of new rocks. This is the simple explanation of formation cycle of sedimentary rocks.
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
Rock formed from the fusion of weathering?
Weathering may change the rock into many shapes.
How does igneous rock changes into sedimentery rock?
By weathering either by physical or chemical weathering.
What effect does weathering have on igneous rock?
The effect of weathering is to reduce the volume of the igneous rock.
Why will a rock weather more rapidly if it is broken into smaller particles?
A rock will weather more rapidly when it is broken into smaller particles because it increases the surface area exposed to weathering agents such as water, wind, and chemicals. This greater surface area allows for more interactions between the rock and these agents, leading to accelerated breakdown and erosion of the rock material.
What kind of weathering is a cracked rock?
It is water weathering
