Why do Small rocks weather more quickly then large rocks?

Small rocks have a higher surface area to volume ratio, which exposes more of their surface to weathering processes like erosion and chemical reactions. This increased exposure makes them more prone to breaking down or weathering quickly compared to larger rocks.


Why does it take less time for small rocks to wear away than it does for large rocks to wear away?

Small rocks have less mass and surface area compared to large rocks, which allows forces like weathering and erosion to act more efficiently and quickly break them down. Additionally, small rocks may experience more frequent impacts and movements due to their size, further accelerating the wear and tear process.


How does surface area affect weathering?

Surface area affects weathering by providing more contact between the rock and agents of weathering such as water, wind, and temperature changes. A greater surface area allows for increased chemical and physical breakdown of the rock, leading to faster weathering processes. Rocks with larger surface areas will typically weather more quickly than those with smaller surface areas.


How does mechanical weathering increase surface area of rocks?

Mechanical weathering breaks down rocks into smaller pieces through processes such as frost wedging, root wedging, and abrasion. As the rocks are broken down, their surface area increases because there are more exposed surfaces on the smaller pieces. This increased surface area allows for further weathering processes to act on the rocks, leading to their continued breakdown.


Why does a pile of small rocks wear away more quickly than a single solid boulder of the same size?

A pile of small rocks has more exposed surface area than a single solid boulder of the same size. This increased surface area allows for more interactions with elements like wind and water, leading to faster erosion. Additionally, small rocks can shift and rub against each other, causing abrasion that accelerates the wearing away process.


What cell has a large surface area to absorb water quickly?

Tissue


Would steal wool have a reaction when its wet and put into a container?

It might oxidize (rust). Steel wool has a large surface area, far greater than say a sphere of the same weight. More surface area means quicker oxidization.


What happens to surface area when rocks are broken into smaller pieces?

As a substance is broken, the surface area greatly increases. For example a 2 meter cube has a total surface area of 24 square meters. If a 1 meter cube is cut out of one corner, the total surface area is now 30 square meters.


How is surface area important?

Surface area affects several things, such as how quickly an object cools down; the rate of chemical reactions will also depend on the exposed area.


Explain the relationship between cell surface area and volume as a cell grows larger?

As the volume of a cell grows, the surface area grows but not as quickly.


How does surface area affect the weathering rates?

Surface area directly impacts weathering rates because increased surface area enables more contact between the rock or mineral and weathering agents like water, oxygen, and acids. Rocks with higher surface area - such as those broken into smaller pieces - will weather more rapidly than larger, intact rocks. This is because more surface area provides more opportunities for chemical reactions to occur.


How does thermal condectivity affect rocks?

Thermal conductivity affects rocks by determining how quickly heat is conducted through them. Rocks with high thermal conductivity, such as igneous rocks, conduct heat well and can quickly transfer heat away from an area. This property can influence the temperature distribution within rocks and their response to changing thermal conditions.
