Porous rocks weather more easily for different reasons:
- Many porous rocks are made from softer materials, thus being more easily weathered
- Porous rocks, by definition, tend to have lots of spaces in them where, on a microscopic or even macroscopic level, areas of the rock are not connected on all sides to other rock. As a result, there is less resistance to fracture or other separations
- Water can infiltrate porous rocks and dissolve from the inside as well as the outside - even if only very slowly
- Because water can infiltrate porous rocks, they can be fractured from within when the water freezes

What permeable rock layers or sediments that transmit groundwater freely are called .?
An aquifer transmits ground water freely.
In the rock cycle water and weather wear away rock by the process of?
Weathering.
What dose weather mean?
what dose the weather mean & what is it about & where and why do we have weather
Aquifers are rock layers that are what?
Aquifer are underground areas of saturated permeable rock or sediments above layers of impermeable rock that have the ability to hold/retain ground water, preventing it from percolation and infiltration, thereby serving as a form of natural water storage .
What happens to the rate at which a rock will weather when it is broken up and why?
The rate of decomposition of the rock will increase when it is broken up because there is more surface area exposed to the elements weather) that can erode the surfaces.
Does groundwater stop moving downward when it meets a preamble rock?
idk... i need to know too. someone please help. my guess is no.... because permeable rock is rock that can be easily passed through.
Why does a permeable rock weather chemically at a fast race?
water steeps in the cracks.
What conclusion would you get from least permeable rock and most permeable rock?
rock type
Are Aquifers rock layers?
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
What types of rock does carbonic acid weather easily?
calcite
What types of rock weather more easily?
Two of them are chalk and sandstone.
Why does permeable rock weather faster than a rock that is not permeable?
Permeable rock tends to be sedimentary rock, formed by silt deposits building up over long periods of time. They tend to be softer than igneous rock which are normally not permeable. Softer rock is worn faster than hard rock but additionally, the absorption of water can also contribute to weathering, especially in regions where the water can freeze and thaw within the rock. The freezing of water causes the rock to crack and loosen, so hastening the loss of solid rick. Igneous rock does not absorb water and so suffers damage due to ice far less than sedimentary rocks.
Factors that affect rates of weathering (rock type)?
Two key factors affect the rates of weathering rock type and climate. Rock type: Minerals that dissolve easily weather faster, softer materials break apart more easily, porous minerals weather more easily.
What is a stone that does not weather easily?
Quartzite, a metamorphic rock, is particularly resistant to weathering.
What is a rock that is permeable?
Limestone and Chalk.
Is sedimentary rock permeable?
yes
What is soil and rock that allows water to pass through it called?
permeable rocks
