Is the acids from a plants' roots that break up rock an example of mechanical weathering?
No, the acids from a plant's roots that break up rock is an example of chemical weathering, not mechanical weathering. Chemical weathering involves the breakdown of rocks through chemical processes, such as acids dissolving minerals in the rock. Mechanical weathering, on the other hand, involves the physical breaking down of rocks into smaller pieces without altering their composition.
Which of these are not Not a source pf mechanical weathering?
Precipitation (source of chemical weathering) Plant roots (source of chemical weathering) Freezing and thawing (source of mechanical weathering) Human activities (source of mechanical weathering)
Living things play no role in physical or chemical weathering?
Actually, living organisms can play a significant role in both physical and chemical weathering processes. For example, tree roots can break apart rocks through physical weathering, while certain microorganisms can produce acids that contribute to chemical weathering. In general, the presence of living organisms can speed up the weathering of rocks and minerals.
Is tree roots cracking the concrete foundation of a house mechanical or chemical weathering?
The process of tree roots cracking concrete foundations is primarily considered a mechanical weathering process. In this case, the physical force exerted by the growing roots causes the concrete to crack. Chemical weathering involves changes in the chemical composition of materials, which is not the primary factor in this scenario.
Contrast mechnaical and chemical weathering and give examples of each?
Mechanical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, such as from frost wedging or abrasion. Chemical weathering, on the other hand, involves the alteration of rock minerals through chemical reactions, like dissolution by acidic rain or oxidation. An example of mechanical weathering is root wedging, where plant roots grow into cracks and break apart rocks, while an example of chemical weathering is the rusting of iron due to exposure to oxygen and water.

How are mechanical and chemical weathering affected by plants?
to be honest in mechanical weathering plants grow their roots in the cracks of rocks. In chemical weathering plants grow their roots in the cracks of rocks, and the roots release acid that weathers away the rock.
What Examples of physical weathering and chemical weathering?
An example of Physical Weathering is plant wedging, where a plant finds its way into a rock and its roots wedge the rock apart. An example of Chemical Weathering is Acid Rain, where chemicals in the clouds caused by global warming rain down and dissolve rocks. Thousands of years of acid rain can result in discoloring and the breaking down of rocks.
Which of these are not Not a source pf mechanical weathering?
Precipitation (source of chemical weathering) Plant roots (source of chemical weathering) Freezing and thawing (source of mechanical weathering) Human activities (source of mechanical weathering)
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 is mechanical wearthering?
Mechanical weathering is the process of weathering that causes disintegration in rocks but does not change the chemical compound of the rocks. Things like frost, rivers, and tree roots cause mechanical weathering. A large example of this would be the Grand Canyon in Arizona.
Physical weathering example?
Like plant-roots,wind,and temperature.
Water causes what type of weathering?
Water causes mechanical and chemical weathering.
How are mechanical weathering and chemical weathering alike and different?
The differences are that mechanical weathering is the breaking of rock into smaller pieces by forces due to gravity, corrosion, freezing (dilatation of the material) and melting of water, plant roots, or other forces. (The mechanical does it physically)So then chemical weathering is the changing of materials in a rock by chemical processes, for example acidic rains action, solubility of some components, chemical reactions, thermal decomposition, etc.
