Rocks are hard because the atoms comprising the minerals which are present in rocks have formed a latticework which make them solid and very stiff. Solid, stiff objects require a significant load applied over a small area to undergo deformation.
well It Is hard because all rocks are hard
They're hard AND the float on magma.
There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
Solid rocks are compacted and hard materials composed of minerals and other substances. They are formed through the process of lithification, which involves the compaction and cementation of loose sediments or the recrystallization of existing rocks. Solid rocks make up the majority of the Earth's crust and can be classified into three main types: igneous, sedimentary, and metamorphic rocks.
There are many different types of minerals and rocks and they are sometimes hard to distinguish one from another. Apatite rocks are usually transparent green.
Hard.........l
they can be as hard as a rock
well It Is hard because all rocks are hard
the look and feel of sedimentary rocks are sometimes hard and smooth or hard and rough
Hard matrix is supposed to be used for digging hard rocks and soft matrix for soft rocks. It's quite confusing to me
because the rocks are hard and the plants can't mack their roots to go throw them
No. Just solid.
hard
Granite
There is no immediate effect if the rocks are hard and solid.
Big sharp rocks can be. Because big rocks is hard and it can break it's hard bone. While big sharp rocks can hurt them more than the big ones. Because big sharp rocks can point hard the crocodile's skin and it can break it's hard bone.
how can you test a rock how hard it is
