Are Basalt And Granite Both Volcanic

Explain the parts of a volcano.

Are basalt and granite both volcanic.

Its principle minerals include pyroxene feldspar and olivine. Basalt and granite actually have quite a bit in common. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. Andesite is a fine grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Compared to the familiar granite of the continents basalt ba salt is darker denser and finer grained. However basalt is considered a volcanic rock and granite is considered a plutonic rock. It forms from lava flows which extrude onto the surface and cool. Basalt and granite are both examples of igneous rock formed as part of a volcanic process.

Show the students samples of basalt obsidian and granite. Draw the diagram to the right on the board. Used by aztecs and mayans traditional molcajetes are made of basalt a dark porous rough volcanic stone. Summary of basalt vs.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. It is common both on earth and other planetary bodies. Both are made up of minerals from the silicate group so both have large amounts of silicon and oxygen. The porous material allowed the molcajete to become seasoned over a period of time much like today s cast iron skillets.

Basalt and granite are both fantastic materials providing a high class finish. The temperature of lava is between 1100 to 1250 c when it gets to the surface. The basalt was used because its weight and texture made it good for grinding. Natural stone is a long life product that can be fashioned to suit.

Basalt forms when lava reaches the earth s surface near an active volcano. Granite and basalt are both igneous rocks. Granite and basalt are both igneous rocks. Some of it erupts on land too but to a first approximation basalt is an oceanic rock.

Emphasize that plutonic rocks form underground while volcanic rocks cool on the surface. However basalt is considered a volcanic rock and granite is considered a plutonic rock. Basalt is the dark heavy volcanic rock that makes up most of the world s oceanic crust. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
