Are Basalt And Granite Both Volcanic

Basalt and obsidian are volcanic rocks.

Are basalt and granite both volcanic.

Granite and basalt are both igneous rocks. However basalt is considered a volcanic rock and granite is considered a plutonic rock. The temperature of lava is between 1100 to 1250 c when it gets to the surface. It is common both on earth and other planetary bodies.

Some of it erupts on land too but to a first approximation basalt is an oceanic rock. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Granite and basalt are both igneous rocks.

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. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Basalt and granite are both fantastic materials providing a high class finish.

Basalt is the dark heavy volcanic rock that makes up most of the world s oceanic crust. Both are igneous rocks which means that they cooled from a magma the earth gets very hot just below the surface and there is lots of liquid rock available. Natural stone is a long life product that can be fashioned to suit. Emphasize that plutonic rocks form underground while volcanic rocks cool on the surface.

Summary of basalt vs. However basalt is considered a volcanic rock and granite is considered a plutonic rock. The porous material allowed the molcajete to become seasoned over a period of time much like today s cast iron skillets. Compared to the familiar granite of the continents basalt ba salt is darker denser and finer grained.

Used by aztecs and mayans traditional molcajetes are made of basalt a dark porous rough volcanic stone. The basalt was used because its weight and texture made it good for grinding. It forms from lava flows which extrude onto the surface and cool. Andesite is a fine grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Its principle minerals include pyroxene feldspar and olivine. Draw the diagram to the right on the board. Basalt and granite are both examples of igneous rock formed as part of a volcanic process. Explain the parts of a volcano.
