Physical weathering can break down a sample by causing mechanical disintegration through processes like frost wedging, abrasion from wind or water, or thermal expansion and contraction. This can lead to the fragmentation and breakdown of the sample into smaller pieces over time.

Over time how might the grass growing up through a crack in a sidewalk affect the sidewalk Use the terms and ldquophysical weathering and rdquo and and ldquochemical weathering and rdquo in your answe?
The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
Are weathering and erosion the same process?
Both chemical and mechanical weathering breakdown a rock into particles, just in diffrent ways. Mechanical weathering is the physical weathering in which a rock is broken down into particles. Chemical weathering is the weathering in which rocks are disolved, decomposed , or loosend to change the minerals in the rock.
How might a earthworm cause physical weathering?
Earthworms can cause physical weathering by burrowing through soil, which can create tunnels that allow air and water to penetrate deeper into the ground. As they move through the soil, earthworms can also push rocks and sediment to the surface, exposing them to the elements and contributing to the breakdown of rocks through processes like frost wedging.
How it might cause physical weathering?
Physical weathering can occur when water seeps into cracks in rocks and freezes, causing the water to expand and break the rock apart. Additionally, wind carrying abrasive particles can wear down rock surfaces through abrasion. Finally, repeated heating and cooling of rocks can cause them to expand and contract, leading to fractures and disintegration.
Is the erosion and weathering a chemical change?
Erosion and weathering are physical processes that break down rocks and minerals without changing their chemical composition, so they are not considered chemical changes. Erosion involves the movement of rock and soil particles by wind, water, or ice, while weathering refers to the physical or mechanical breakdown of rocks.
What weathering conditions might affect copper?
There are a few different weathering conditions that might affect copper. Rain and snow are some conditions that would affect copper.

How might choosing a small sample size affect a scientific investigation?
Statistically the results will not be scientifically valid if the sample size is too small.
How the rates of mechanical and chemical weathering might differ in the Congolese rain forest and the Siberian steppes?
The rates of mechanical weathering does not affect anything since the chemical properties remain unchanged. Only chemical weathering affects the chemical properties of an object.
Which substance is most resistance to weathering?
Quartz is one of the most resistant minerals to weathering due to its hardness and chemical stability. It is not easily broken down or altered by physical or chemical weathering processes.

How might an overgrowth of vegetation in a river affect its physical characteristics?
decreased water flow
Image the temperature inside earth was no longer hot how might this affect the rock cycle?
Rocks and the Rock Cycle. ROCKS: Rocks, rocks, rocks. Weathering is all about rocks.

How the rates of mechanical and chemical weathering might different in the Congolese rain forest and the Siberian steppes?
In the Congolese rainforest, the rates of chemical weathering are likely higher due to the warm and wet climate, which accelerates chemical reactions that break down rocks. In contrast, in the Siberian steppes, mechanical weathering rates might be higher due to freezing and thawing cycles that physically break down rocks through processes like frost wedging.
