What is a specific example of a rock formed by molten material cooling?
Granite, rhyolite, obsidian, basalt, pumice, gabbro, diorite; all examples of igneous rock that by definition forms from the cooling of molten rock.
How can you tell that gabbro crystalized deeper underground than basalt did?
Gabbro has larger crystals, meaning it had much more time to solidify from magma underground. Larger crystals in igneous rock are an indication of longer cooling times, which result in larger crystal growth.
How much gabbro is in olivine?
Olivine does not contain Gabbro. Gabbro can contain olivine. Usually no more than a few percent.
Is gabbro a phaneritic rock?
Yes, Gabbro is a phaneritic igneous rock.
What rate of cooling produces the largest crystals in igneous rocks?
A slow rate of cooling. The slower a magma cools, the longer the crystals have to grow, thus the bigger they will be.
Is gabbro made from magma that cooled slowly?
Gabbro is formed from slow cooling basaltic magma.
Does gabbro cool above ground or under?
Gabbro is the product of slow cooling of mafic magma below the surface.
Where is basalt and gabbro formed?
Basalt and gabbro are chemically equivalent rocks. Basalt solidifies above ground and gabbro solidifies below ground.
What are two igneous rocks formed from slow cooling magma?
Granite and Gabbro.
What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
What is a dark dense rock that is rich in iron and produced by cooling magma?
Mafic igneous rocks, like basalt and gabbro.
What is the effect of cooling on pulse rate?
Cooling slows heart rate, thus slowing the pulse rate.
What is a specific example of a rock formed by molten material cooling?
Granite, rhyolite, obsidian, basalt, pumice, gabbro, diorite; all examples of igneous rock that by definition forms from the cooling of molten rock.
Is a gabbro a mineral?
Gabbro is a rock
How can you tell that gabbro crystalized deeper underground than basalt did?
Gabbro has larger crystals, meaning it had much more time to solidify from magma underground. Larger crystals in igneous rock are an indication of longer cooling times, which result in larger crystal growth.
What type of texture does gabbro have?
Gabbro is coarse textured.
Is gabbro volcanic?
No. Gabbro is an intrusive igneous rock.
