Compare and contrast magma and lava. Why do scientists consider these materials separately? What will be an ideal response?
The student should recognize that magma is molten rock below the surface of Earth and lava
is molten rock above the surface of Earth. The most important reason that scientists consider
these two materials separately is that their cooling rates are very different. Magma cools very
slowly because it is insulated by surrounding rock and lava cools very quickly because it is in
contact with air or water.
