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.

∙ 11y agoOne way that minerals become dissolved in groundwater is through chemical weathering. As water moves through soil and other organic materials, the water combines with carbon dioxide to form carbon acid. This weak acid chemically weathers the rock that the acid passes through by breaking down and dissolving the minerals in the rock.

Can water alone weather some rocks?
Yes. The force of moving water itself can cause parts of the main rock body to break off. Additionally, acids present in rain or groundwater can chemically weather rock.
What types of sedimentary rocks are there?
Physically/mechanically formed sedimentary rock, organically/biologically formed sedimentary rock, and chemically formed sedimentary rock.
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.
What process will most likely chemical weather on iron-rich rocks?
Corrosion will most likely chemically weather an iron-rich rock.
How can water wear away solid rock?
The water can be chemically attacking the minerals contained in the rock, or be the medium which carries abrasive rock particles which weather solid rock. The power of moving water can tumble rocks into each other, rounding them and reducing their size, in the same principle as a rock tumbler. Crashing waves can pound into rock cliffs, reducing them to rubble, where they can be further weathered by the previously mentioned water effects. Pressures caused by freezing and thawing water in rock fissures will also reduce rock size.
Why does a permeable rock weather chemically at a fast race?
water steeps in the cracks.
Can water alone weather some rocks?
Yes. The force of moving water itself can cause parts of the main rock body to break off. Additionally, acids present in rain or groundwater can chemically weather rock.
What is a chemical or physical process in which rocks exposed to the weather are worn down by water wind or ice?
Smaller particles of rock are produced from larger particles.
What types of sedimentary rocks are there?
Physically/mechanically formed sedimentary rock, organically/biologically formed sedimentary rock, and chemically formed sedimentary rock.
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 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.
What process will most likely chemical weather on iron-rich rocks?
Corrosion will most likely chemically weather an iron-rich rock.
How does melting water weather a rock?
the water freezes and then cracks 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.
What agent of weathering can affect a rock both chemically and mechanically?
Hail. when it melts, water can damage the rock.

Where does rock come from tell the answer?
Rock is soil compacted and changed physically and chemically over thousands of years. The changes are due to temperature, pressure and various chemicals in the area that process is taking place.
