Is igneous harder than sedimentary rocks?
They are generally harder because of their interlocking crystalline structure and mineral composition.
More often than metamorphic or igneous rocks sedimentary rocks have what?
Sedimentary rocks have numerous fossils
How does sedimentary rock form to metamorphic rock?
Shale (a metamorphic rock) goes through heat and pressure than it turns into slate (a sedimentary rock)
What do Metamorphic and Sedimentary rocks have in common?
It is more likely that igneous and metamorphic, or igneous and sedimentary rocks would have something in common than sedimentary and metamorphic. The reason is because the processes involved in making metamorphic rocks is completely different than the processes needed to make sedimentary rocks. Only high temperature, high pressure minerals such as olivine, pyroxene, amphibole can withstand these kinds of conditions. Take quartz and feldspar, two of the most abundant minerals found in sedimentary rocks, these minerals would not be found in abundance in metamorphic rocks because they are not high temperature, high pressure rocks. But the most simple answer is that all the major groups of rocks are made of minerals. Metamorphic has high pressure and Igneous does to and both made from a particle called magma.
Is sandstone extrusive?
sedimentary rock are extrusive when the were formed outside land than in the dirt extrusive rocks take less time to form than intusive (formed under ground) becase wind and help it form faster. i hope this is very helpful =)
Which rock would be harder to break with a hammer a sedimentary rock or an igneous rock?
You would normally think that an igneous rock would be harder to break. However, it completely depends on which igneous rock is being compared to which sedimentary rock, as their resistance to breakage is so varied. There are some igneous rocks (obsidian and pumice, for example) that would break much easier than some sedimentary rocks, such as chert or flint.
Is igneous harder than sedimentary rocks?

More often than metamorphic or igneous rocks sedimentary rocks have what?
Sedimentary rocks have numerous fossils
What do sedimentary rocks have more often than metamorphic or igneous rocks?
Sedimentary rocks have numerous fossils
Which is older igneous or sedimentary?
Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks. However, igneous rocks are formed from magma within the earth's crust, or as it extrudes onto the surface, while sedimentary rocks are formed from the erosion and redeposition of existing rocks, so generally in the life cycle of a rock the igneous form would come first.
What are the three types of rock and their formation?
there are 4 bill bob and jerry and the one in abi's head she likes to call a brain Igneous, Sedimentary, and Metamorphic.
What other types of rocks are there other than igneous sedimentary and metamorphic?
There are extraterrestrial rocks.
More often than metamorphic or igneous rocks sedimentary rocks have?
numerous fossils
Are sedimentary rocks softer than igneous rocks?
yes because it is sedimentry isnt it ]
How hard are sedimentary rocks?
harder than metamorphic
Are igneous rocks less porous than sedimentary rocks?
Sedimentary rocks tend to be more porous than igneous rocks because there is more open space between the individual sediment grains than between the minerals in a crystallized rock.
Can slate be worn away easily?
As slate is a metamorphic rock, it can't be worn easily. I t would be harder to wear than igneous or sedimentary rocks.
