A fine-grained rock will weather faster than a coarse-grained rock because it has more surface area exposed to weathering agents like water and air. This increased surface area allows for more chemical reactions and physical breakdown to occur, leading to faster weathering.
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Coal is fine grained, lack of visible texture.
Limestone can be both coarse-grained and fine-grained, depending on its composition and how it formed. Coarse-grained limestone typically contains larger mineral grains visible to the naked eye, while fine-grained limestone has smaller mineral grains that are not easily seen without magnification.
Unfractured granite probably has the lowest porosity among the options given. Granite is a dense, crystalline rock with a low porosity due to its solid mineral composition and lack of fractures or pore spaces.
Silt is a fine-grained fertile soil deposited by water.
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
Yes extrusive rocks are fine grained because they cool down at a faster rate.
shale is fine grained
Extrusive igneous rocks are fine grained due to fast cooling. They cool at a faster rate than most igneous rocks.
fine grained
Fine grained has larger crystals and coarse grained has smaller crystals
Fine grained has larger crystals and coarse grained has smaller crystals
coarse grained
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
fine grained
fine grained rock will weaher faster thatn the course grained rock
