What happened to lava when it cools?
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
When lava cools quickly large crystal form?
No. Small crystals form.
What Extrusive igneous rocks form when hardens and cools.?
lava
Which features may occur when volcano lava cools at the surface?
Lava that cools at the surface can form features such as lava flows, which are large sheets of solidified lava. It can also create lava tubes, which are tunnels formed when the outer layer of the lava flow cools and hardens while the inner lava remains molten and continues to flow. Additionally, lava may form spatter cones or lava fountains when ejected into the air and solidifies before hitting the ground.
What formation is formed once lava cools and becomes hard?
igneous rocks form
What happened to lava when it cools?

How do igenous rocks form?
They form when magma or lava cools and solidifies.
What does lava that cools quickly form?
fast cooling lava -small crystals or no crystals
What lava that cools quickly form?
fast cooling lava -small crystals or no crystals
When lava cools quickly large crystal form?
No. Small crystals form.
What Extrusive igneous rocks form when hardens and cools.?
lava
Does lava cool quickly and form minerals with small crystals?
Yes. The faster lava cools, the less time crystals have to form. If the lava cools slowly and has a low viscosity, atoms are able to move around more and form larger crystals.
How does a volcanoes lava form a mountain?
Lava cools down and accumulates into rock as it reaches Earth's surface
What rocks form when magma or lava hardens and cools?
Igneous rock.

What happens when lava flows reach the sea?
When lava flows reach the sea, the lava rapidy cools to form an igneous rock.
What rock forms from lava that cools?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
