Explain how magma causes a volcano to erupt Be detailed?
magma rises toward earth's surface as long as it is less dense than the surrounding rock.
A change in magma composition due to melting of surrounding country rock is called?
Crystal settling is when the denser minerals and the remaining melt solidifies. The change in magma composition due to melting of surrounding country rock is called assimilation.
Are crystals denser than magma?
Yes.
WHAT happen to density of magma after it being cooled?
As magma cools, it undergoes crystallization, forming solid minerals. This process typically increases the density of the material, as the solid crystals are denser than the molten magma. Additionally, as the temperature decreases, the volume may also slightly contract, further contributing to an increase in density. Overall, cooled magma, now referred to as igneous rock, is denser than its molten state.
Is magma a weathered rock?
No. Magma is molten rock underground.
How is magma and igneous rocks related?
Magma is molten rock, and igneous rock is cooled magma.
How does magma create rock?
Magma is molten rock. It becomes rock by cooling and hardening.
Which type of rock forms from magma?
magma is a mixture of several different types of rock.
How does magma from igneous rock?
magma cools to form igneous rock
Type of rocked formed when lave or magma cools?
A rock that is formed when magma cools is called a igneous rock.
Mafic mineral low or high density?
Mafic minerals generally have a relatively high density compared to felsic minerals. This is because mafic minerals are rich in iron and magnesium, which are denser elements. As a result, rocks rich in mafic minerals like basalt and gabbro tend to be heavier and denser than rocks composed of felsic minerals like granite.
What is the name for molten rock when its under the ground?
Molten rock under the surface is called "magma". When magma reaches the surface it is called "lava".
