Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.

What cools quickly on the earth's surface?
it would be lava , magma is in the ground and flows on earths surface and cools to lava
What is the term for melted rock under Earth's surface?
'Magma' is melted rock occurring under the Earth's surface. When it comes up and flows out on the Earth's surface it is called 'lava'.
Explain the sequence of events that cause the movement of the plates on the earths surface use these terms core heat mantle flow rise sideways drag cools sinks?
Magma gets heated, rises, flows horizontally (the plate over it moves with it, but not as fast as the magma), cools and sinks.
Why does lava take a long time to cool down?
Lava cools slowly because lava is a poor conductor of heat. Lava flows slow down and thicken as they harden.
Groundwater sometimes flows out of the surface in artesian wells?
no
What forms when melted rock flows to the surface and cools quickly?
Sand

What forms when melted granite flows onto the earths surface and quickly hardens?
It forms rhyolite.

What happens when molten lava flows on the surface of earth?
It cools and forms new land.
What is an mountain that forms when hot melted rock flows through a crack onto the surface of earth?
a volcanoe
What is the melted rock which flows out of the earths surface is called?
Magma, or pyroclastic flow.
Does lava cool slowly or quickly?
Magma that cools quickly forms into igneous rock, when it cools quickly it becomes a lava rock. Lava cools very quickly at first and forms a thin crust that insulates the interior of the lava flow.
Where does lava go when it erupts?
When lava reaches the surface, it quickly hardens into rock. The resulting rock will have either a glassy texture (with no crystals) or have a fine-grained texture (with small crystals) because the minerals have little or no time to crystallize.
Is lava that flows onto the earths surface called magma?
This word has its origin in the Greek language, where it is related to 'to knead'; thus recognizing it being formed from a plastic material that is re-shaped.
When lava flows and cools on Earth's surface it forms what kind of rock?
Igneous rock is formed through the cooling and solidificatio of magma or lava.
What are the two definitions of the term volcano?
a moutain that forms when red hot melted rock flows through a crack onto earths surface
