What is a hardened layer of magma called?
A hardened layer of magma is called a lava flow or volcanic rock.
What do the crystals that form in slowly cooled magma produce?
A crystal is a homogeneous solid substance that has a natural geometrically regular form. The crystals that form in slowly cooled magma produce large grains.
Oceanic crust is formed of how many layers?
Oceanic crust typically consists of two layers: the top layer being composed of young basaltic rocks that have cooled from magma at mid-ocean ridges, while the bottom layer is made up of more dense gabbroic rocks that form from the crystallization of magma beneath the seafloor.
What does obsidain's glassy texture indicate about how magma cooled?
Obsidian's glassy texture indicates that the magma cooled rapidly, preventing crystallization of minerals. This rapid cooling does not allow enough time for the minerals to form and grow, resulting in the formation of an amorphous, glass-like rock.
What feature in igneous rocks is the best indication of how rapidly the magma crystallized?
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.
A rock made from cooled magma or lava?
Igneous rock is formed from solidified and cooled magma or lava.
What creates the crust?
cooled magma
Is there magma on Mars?
No. Mars has cooled so that i can no longer produce magma.
How is magma and igneous rocks related?
Magma is molten rock, and igneous rock is cooled magma.
Is crust formed by cooled magma?
yes
What is Igneous rock is made from?
They are made from cooled lava, because they come from volcano's, and the center of the earth, which has magma (lava) flowing around.no
What is the name of a magma cooled on the surface?
When magma cools on the surface it forms igneous rock.
What is it called when a rock has cooled from magma?
When a rock has cooled from magma, it is called an igneous rock. This process involves the solidification of molten rock material.
When Magma is cooled what rock forms?
igneous rocks
In domed mountains it is what?
cold because there is cooled magma
Is gabbro made from magma that cooled slowly?
Gabbro is formed from slow cooling basaltic magma.
What is magma called when cooled slowly?
It will convert from magma to some form of intrusive igneous rock.
