What else can I help you with?
Water seeping into the joints or seams of a rock and then freezing can weather the rock. This is an example of what type of weathering?
This is an example of mechanical weathering, specifically known as frost wedging. As water freezes, it expands and exerts pressure on the rock, causing it to break apart. Over time, this process can lead to the disintegration of the rock into smaller pieces.
What type of weathering need temperature changes to make them happen?
Freeze-thaw weathering, also known as frost weathering, requires temperature changes to occur. This process involves water seeping into cracks in rocks, freezing during cold temperatures, expanding, and then thawing when temperatures rise. This repeated freezing and thawing of water helps break apart the rock.
What are four physical processes of weathering?
Four physical processes of weathering include abrasion (mechanical wearing down of rock surfaces due to friction), freeze-thaw cycle (water seeping into cracks and freezing, expanding, and breaking apart the rock), exfoliation (peeling away of outer layers of rocks due to pressure release), and root wedging (plant roots growing into cracks and forcing the rock apart).
How is it possible for weathering to take place beneath bedrock?
Weathering can occur beneath bedrock when water seeps through cracks and crevices, carrying minerals and chemicals that can dissolve or break down the rock. Over time, this process can weaken and eventually change the properties of the bedrock from underneath. This type of weathering is known as subterranean weathering.
Which scenes show examples of mechanial weathering why?
Scenes where rocks are being broken down by processes like frost wedging, root wedging, and abrasion would show examples of mechanical weathering. For example, scenes depicting water seeping into cracks in rocks and freezing, causing the rocks to break apart, or roots growing into cracks and breaking rocks apart would be examples of mechanical weathering. You might also see scenes where rocks are being worn down and smoothed by constant rubbing or hitting against each other.
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 kind of weathering do workers who seal cracks in the rocks protect Mt Rushmore from?
Workers who seal cracks in the rocks at Mount Rushmore protect it from physical weathering caused by water infiltration and freezing and thawing cycles. By sealing the cracks, they prevent water from seeping into the rocks, which can weaken and cause them to break apart over time.

How does water seeping through air spaces in rock affect it?
Water seeping through air spaces in rock can promote weathering processes such as freeze-thaw cycles and chemical weathering. This can lead to the gradual breaking down of the rock into smaller particles and weaken its overall structure over time. Additionally, the presence of water can facilitate the growth of plants or organisms that further contribute to the breakdown of the rock through biological weathering.
Why is Mechanical weathering is more rapid in warm wet climates?
Mechanical weathering is more rapid in warm wet climates because water facilitates the breakdown of rock by seeping into cracks and crevices and then freezing and expanding, causing the rock to break apart. The combination of high temperatures and moisture also promotes the growth of vegetation with root systems that can further break apart rock through expansion and contraction.
What causes potholes and breaks in rocks from freezing an thawing cycle is what?
Potholes and breaks in rocks from the freezing and thawing cycle are caused by water seeping into cracks in the rock, freezing and expanding, and then thawing and contracting. This repeated cycle weakens the rock and can eventually lead to the formation of potholes or breaks.
How can water cause both mechanical and chemical weathering?
Water causes mechanical weathering by seeping into cracks and then freezing. When water freezes, it expands, which causes the cracks to widen. An example of chemical weathering is when compounds in the rocks dissolve in water and are carried away. Salts are a prime example of this. Billions of years of this have made our oceans salty. Water, when it appears in large quantities at some altitude, rushes downhill under the influence of gravity. In this rush, it shreds soils and sweeps sands and gravels into the unknown downstream. All this moving water carries small abrasive particles in it, and these will "sand down" rocks and just about anything else in the flow. If water creeps into cracks and crevices in rock and then freezes, it will break out tiny pieces of the rock. We know water expands when it becomes ice, and this mechanical pressure is almost irrestible. Rock is pulverized, and though each even is on a small scale, across a broad area and through a long period of time, it can make mountains disappear.
Why is water seeping into the ground?
If water is seeping into the ground near your pool, then you obviously have a leak somewhere.
