Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Coarse
it is fine-grained
It is an igneous (volcanic rock).
Tuff.
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.
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.
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
fine grained or coarse grained
Metamorphic rock can be coarse grained or fine grained.
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.
Coarse
when the lava cools quickley it is fine-grained
fine grained rock will weaher faster thatn the course grained rock
Methods of formation. If crystalline (igneous or metamorphic) they would most likely have had differing rates of cooling. If sedimentary, they would most likely have had differing depositional environments (higher energy for larger grain sizes).
