Q

What is the difference between lava and magma?

A

Magma- Found underneath the earth and is used to create intrusive igneous rock
Lava- Found Outside the earth and is used to create extrusive igneous rock

Q

What crystal size is in intrusive igneous rock?

A

Large crystals

  • Cooling rate is slower- more time to form
  • Small temp. difference between lower mantle and crust
