Because they are part of this world. They were made from lave, from a volcano. So there fore they are imporant Igneous rock. I prove this fact because they say it's important in the question you asked. An a group of scientistes have proved my theory because they have these types of rocks in their labs. You could also ask a teahcer, maybe a science teacher, a math teacher won't know.
Igneous rocks
Both are igneous rocks.
Sedimentary rocks (such as sandstone and limestone), igneous rocks (such as granite and basalt), and metamorphic rocks (such as marble) are all used in masonry.
Probably not very much, igneous rocks are caused through the cooling of magma or larva and are very common on earth. Granite and Basalt are examples of igneous rocks.
Without igneous rocks, we would not have beautiful granite countertops.
Basalt and Granite are igneous rocks which are very hard.
Three types of igneous rocks are pumice, basalt, and granite.
Igneous rocks
They are all igneous rocks.
Granite basalt pumice aplite scoria
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
Both are igneous rocks.
Granite and Basalt.
Igneous Rocks: Basalt and Granite
Granite and basalt are both igneous rocks; however, basalt is considered a volcanic rock, and granite is considered a plutonic rock.
Igneous, examples include Granite and Basalt
Both are igneous rocks.
