What term describes an igneous rock that forms quickly on earths surface from cooling lava?
Extrusive.
How are crystals formed and how does the rate effect the crystal?
Crystals that are formed below the surface are formed by the cooling of magma. Crystals above the surface are formed when a volcano erupts, and cools, again, above the surface. Crystals that are below the surface usually have a slower rate of cooling than those above the surface, causing bigger crystals because of the slower cooling:)
Under which condition below would you expect a glassy extrusive rock like obsidian to form?
Obsidian is formed as extruded lava with a high silicon content that cools quickly. So the environment would be a volcano.
How do you tell if a rock is intrusive?
Intrusive rocks are formed from cooling magma beneath the surface. The opposite would be an extrusive rock, these rocks form from lava cooling on the surface of the earth.
Igneous rocks that cool quickly below earth surface are?
well the type of rock they are is intrusive rocks, but the actual name is probably something quite different

Extrusive.
What is the surface cooling that results when a substance evaporates?
surface cooling occours when a substance evaporates after taking sufficient heat from the body itself intended to be cooled, creates a sensation of cooling on the body. But in air conditioning the surface cooling, is one of the method of cooling, having different explanation.
What would the crystal size of a rock be like if it started to cool slowly deep inside earth then was moved toward the surface and finished its cooling quickly?
big
Could phenocrysts be found in an obsidian?
No, phenocrysts are typically minerals that form in slowly cooling magma and are therefore not found in obsidian, which is a type of igneous rock that cools quickly, resulting in a glassy texture without crystal growth.
How does surface area affect the rate of cooling of soup?
Increased surface area increases cooling. Cooling occurs by convection of air above the soup and water vapour loss.
What does Lava on the surface of the earth do quickly?
Lava on the earth's surface will cool quickly.
How does unequal heating and cooling of earth surface cause severe weather?
because it is cooling

What is the difference between instrusive rocks and extrusive rocks?
Extrusive rocks form above the surface, cooling quickly and bearing a glassy or fine texture and may be vesicular. Intrusive rocks form below the surface and form slowly, giving it a coarse texture.
When suns light hits a surface of the earth more directly as the area around the equator what happens?
the earth would probably explode
Epicenter?
the location on the surface directly above the focus
