water causes mechanical weathering of rocks in two ways:
*the force of moving water (such as running water anf waves) scrapes and breaks rocks
* alternate freezing and thawing of water in rock crevices eventually break rocks in countries that experience winter.

What process will most likely chemical weather on iron-rich rocks?
The most likely process that will chemically weather iron-rich rocks is oxidation. When iron is exposed to oxygen and water, it can react to form iron oxide, commonly known as rust. This process weakens the rock structure and can eventually lead to the breakdown of the rock into smaller fragments.
Can water alone weather some rocks?
Yes, water alone can weather rocks through a process called erosion. Over time, water can dissolve and break down rocks, changing their composition and shape. This process is a natural part of the rock cycle.
How acids in living things weather rocks?
The acids chemically weather rock by breaking up their chemical composition, which eventually causes the rock to lose mass by decomposition.
Ow does sea water affect rocks?
Sea water can chemically weather rocks through processes like dissolution and oxidation, which erode and break down rock minerals over time. The presence of salt in seawater can also lead to salt crystallization within rock pores, weakening and causing cracks to form. Erosion from waves and tides can physically break down rocks into smaller pieces through abrasion.
What does water do to a rock?
water affects rocks when water rubs against rock for a long long time the rock starts to weather away so it breaks inti small particles. Also if water comes in contact with the rocks, it would have to go around the rock therefore it slows the flow of the water down. If the rocks had holes in the middle it wouldn't really slow the water down but it only a little. That's because the water still kind of has to go over the base of the rock. Also if rocks were naturally piled up with no gaps and they're too high for the water to go over, then the water would have to stop and flow to the side not forward so that it could get back on track.
Why does a permeable rock weather chemically at a fast race?
water steeps in the cracks.
How does melting water weather a rock?
Melting water can weather a rock through a process called frost wedging, where water seeps into cracks in the rock, freezes and expands, causing the crack to widen. This cycle of freezing and thawing can break apart rocks over time. Additionally, the flowing water can chemically weather the rock by dissolving minerals and carrying them away.
Is water chemical weathering physical weathering or both?
Water contributes to both chemical weathering and physical weathering. Through processes like hydration and dissolution, water can chemically break down rock minerals. Additionally, water can physically weather rocks through processes like freeze-thaw cycles and abrasion by moving water.
How do oxygen chemically weather rocks?
There is no significant weathering from oxygen. However, the particles in the wind (oxygen) can weather a rock.

How does moving water weather rocks?
Moving water can weather rocks through a process called abrasion, where the water carries sediment that physically rubs against the rock, wearing it down. Chemical weathering can also occur as the water interacts with minerals in the rock, causing them to dissolve or break down. Over time, these processes can shape and erode the rock, changing its appearance.
What agent of weathering can affect a rock both chemically and mechanically?
Hail. when it melts, water can damage the rock.

How do you account the shortage of feldspar in the soil?
It is easily chemically weather, so it gone by the time a rock becomes a soil.
