What three factors affect the formation of magma?
1. the coarse grained rock 2. slow cooling magma 3. fine grained rock
What rock type is formed from the slow cooling of magma under the earths surface?
Magma cooling beneath the surface creates intrusive igneous rocks.
What is slow cooling magma far beneath earth's surface?
The slow cooling of magma far beneath earth's surface creates the rock inside earth to change slowly... this means that earths surface changes in times because of this cooling magma.
What rock most likely formed underground from slow cooling magma?
Igneous
Formed from slow cooling magma speckled with large minerals grains?
Granite
How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
Slow cooling of hot magma lead to the formation of what crystals?
large crystals
What three factors affect the formation of magma?
1. the coarse grained rock 2. slow cooling magma 3. fine grained rock
Is basalt formed from slow or rapidly cooling magma?
Basalt is formed from relatively rapid cooling magma.
What is the rate of cooling in reference to magma and lava?
The rate of cooling is the speed at which magma or lava crystallizes. When the speed is slow it results in big crystals. When the speed is fast it results in small crystals.
How do the crystals in the pegmatites form?
slow cooling of gaseous magma
Is gabbro made from magma that cooled slowly?
Gabbro is formed from slow cooling basaltic magma.
What rock type is formed from the slow cooling of magma under the earths surface?
Magma cooling beneath the surface creates intrusive igneous rocks.
How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
What is slow cooling magma far beneath earth's surface?
The slow cooling of magma far beneath earth's surface creates the rock inside earth to change slowly... this means that earths surface changes in times because of this cooling magma.
What are two igneous rocks formed from slow cooling magma?
Granite and Gabbro.
What is rock body made from slow cooling magma and with a mushroom shape?
A laccolith.
