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

∙ 8y agoCracks in sidewalks primarily occur first due to mechanical weathering, especially near trees, their root systems and/or where soils shifts due to water levels changing in the concrete. Temperature changes throughout the year can also be a factor. Chemical weathering could make cracks worsen, but the crack itself would have most likely begun by mechanical causes.

What are non-examples of mechanical weathering?
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
How do plants cause chemical weathering of rock?
In chemical weathering mosses and linches have been found to grow on rocks and release chemicals that dissolve minerals from rocks. roots from plants are able to invade cracks with in rocks and increase the size of the cracks. There are a number of trees and other plants that release acidic chemicals which can cause weathering of the rocks, minerals, and soil around them. Plants also can have an affect on the way water weathers rocks and soils, they can channel water in specific directions that cause greater weathering or they can lessen the impact of rain falling on the ground. They also affect wind speed and direction near the surface of the ground having an effect on weathering in arid regions of the world.

What is an agent of chemical weathering?
Agents of chemical weathering depend on the climate and composition of the rock that is breaking down. Some Agents would include, water, oxygen, CO2, and acids. Temperature plays a significant role in chemical weathering. If it is warm and wet, the Chemical weathering process will increase. So, really it all depends.
How can you protect your house from biological weathering?
To protect a home from weathering, it should have fresh paint at all times. All surfaces should be sealed and there should be no cracks in the exterior.
Which one of the following is a source of chemical weathering a The abrasion of running water b water freezing in the cracks of exposed rocks c the effects of acid from decaying animals d the growth?
C. The effects of acid from decaying animals
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 is the differences of chemical and mechanical weathering?
Mechanical weathering is the breaking down of rock without chemical reaction.Mechanical weathering is also when water gets into the cracks of the rocks and makes the rocks expand.Like ice wedging.while chemical weathering changes the rocks by chemicals.
Is leaves decaying in the forest a mechanical weathering?
Is repeated freezing and thawing of water that cracks rocks
What are the 2 main types of weathering?
The two main types of weathering are physical weathering and chemical weathering. Physical weathering involves water, wind and dust scraping away at rocks, while chemical weathering involves chemicals, usually acids, breaking down the rock.
What kind of weathering happens when ice forms in cracks in a rock?
When ice forms in cracks in rocks, the kind of weathering is known as mechanical weathering. The type of mechanical weathering that freezes and thaws is frost wedging.
Is oxidation an example of mechanical weathering?
no. oxidation is a chemical reaction that involves an atom or a molecule losing electrons in a chemical reaction. Mechanical weathering would be something like water seeping into cracks in a rock, then freezing and breaking that rock apart.
What are non-examples of mechanical weathering?
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
Animal burrows dug in rock that let in water and air chemical or mechanical?
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
What are the two causes of mechanical weathering?
If you want to draw something of mechanical weathering like me then i got the idea for you draw a rock with cracks and a concrete house with no roof at the top mechanical weathering
What is the type of weathering when ice forms cracks in rocks?
Ice wedging is a form of mechanical weathering.
How does physical weathering make the job easier for chemical weathering?
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.
When a tree cracks a sidewalk is it weathering?
No. Weathering is the action of sun, rain, wind altering the color, texture, composition, or form of exposed objects.
