Why do metamorphic rocks have a higher porosity than sedimentary rocks?
Actually, it's the other way around. Sedimentary rocks have a higher porosity because of the larger spaces between the rock particles which compose them.
Does metamorphic rocks have a higher porosity than sedimentary rocks?
Metamorphic rocks would have less porosity than sedimentary rocks.
The percentage of open spaces between mineral grains in clastic rocks is called?
Porosity refers to the percentage of open space between individual rock particles in a rock layer. This space can be between grains or within the cracks or cavities of the rock.
How does acid water affect rocks?
== == Acidity can dissolve certain rocks through chemical reaction.
What are the spaces between rocks and soil called?

What is it called when a rocks particles come of and make another rock from the particles?
Sedimentary rocks are formed from the fragments of other rocks
Rocks such as sandstone which are formed from particles of other rocks are?
Sedimentary rocks.
Are igneous rocks porous?
Igneous rocks generally have extremely low porosity. An exception is pumice, which has abundant vesicles and therefore is very porous (though not permeable).
What rock is made from particles of other rocks?
Clastic sedimentary rock is composed of cemented particles of other rocks.
Rocks such as sandstone are formed from particles of other rocks are?
Sedimentary.
