Who much of the substance is exposed on the surface?
The amount of substance exposed on the surface depends on the surface area of the substance. A substance with a larger surface area will have more exposed surface compared to a substance with a smaller surface area. Factors like particle size and shape can also affect the amount of substance exposed on the surface.
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.
Which weather faster small rocks or large rocks why?
fine grained rock will weaher faster thatn the course grained rock
What happens to a rocks that are pushed under earths surface and become hotter and experience more pressure?
As rocks are pushed deeper into the Earth's interior, they experience higher temperatures and pressures. This can cause the rocks to undergo changes in mineral composition, texture, and structure through processes like metamorphism. Eventually, these rocks can be transformed into new types of rocks such as metamorphic rocks.
Where are rocks exposed to more wind rain and ice?
Rocks are typically exposed to more wind, rain, and ice in mountainous regions and coastal areas where there are strong weather patterns and erosion processes at play. These environments experience higher levels of weathering and erosion due to the constant exposure to these elements.

How does the size of an exposed rock affect its rate of weathering-?
The size of an exposed rock can affect its rate of weathering because larger rocks have a smaller surface area-to-volume ratio, making them weather more slowly compared to smaller rocks. Larger rocks provide less opportunity for chemical reactions and physical weathering processes to occur on their surfaces. Smaller rocks have greater surface area for weathering agents like water and air to act upon, leading to faster weathering rates.
How does the size of an exposed rock affect its rate of weathering?
The size of an exposed rock can affect its rate of weathering. Smaller rocks have a larger surface area compared to their volume, which exposes more area to weathering agents like water and air, causing faster weathering. Larger rocks have less exposed surface area relative to their volume, so they weather more slowly.
Why are volcanic rocks often exposed at Earth's surface as hills ridges and mountains surrounded by areas of lower elevation?
Volcanic rocks are exposed at Earth's surface as hills, ridges, and mountains because they are more resistant to erosion compared to surrounding rocks. This resistance is due to the harder and denser nature of volcanic rocks, which allows them to withstand weathering and erosion processes better, resulting in the formation of elevated landforms.
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 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.
How does the area of exposed surface affect evaporation?
The larger the exposed surface area, the faster the rate of evaporation, as there is more surface area for the liquid molecules to escape into the air. This is because more molecules are exposed to the air, increasing the likelihood of evaporation occurring. Conversely, a smaller exposed surface area will result in slower evaporation.
Does a larger surface area makes diffusion happen more quickly?
yes. Lets for example take a potato cube put in a jar of water. if the potato cube has a large surface area, then more of its surface will be exposed to water molecules, meaning that more can diffuse into it more quickly.
What is a nonconformities?
Nonconformity - n, In geology, an erosional surface on igneous and/or metamorphic rocks that is overlain by younger sedimentary rocks. The erosion surface indicates that the older igneous and metamorphic rocks once were exposed at the surface. Subsequently, they moved downward, were covered with water, and became the foundation for deposits of younger sediemntary rocks.An nonconformity is a specoial case of the more general term unconformity, which is any discontinuity in the stratratigraphic record.
Why do leave have flat and broad surface?
more the surface area exposed to sun light more will be the rate of photosynthesis
Why can intrusive igneous rocks be left behind when surrounding rocks are worn away?
Intrusive igneous rocks are formed from magma that cools and solidifies beneath the Earth's surface. They are more resistant to weathering and erosion compared to surrounding rocks, which are often sedimentary or metamorphic in nature. Therefore, when the less resistant rocks are worn away, the intrusive igneous rocks are exposed at the surface.
