|
what is a tectonic plate?
Parts (pieces)of the lithosphere floating on the asthenosphere
|
|
What are 7 tests to find out which mineral it is.
Luster, color, streak, hardness, cleavage, density, fracture.
|
What is the rock cycle
A series of changes to a rock creating, changing, and destroying.
|
What are the characteristics of the mantle
Thickest layer and is divided into 3 layers. The lithosphere, asthenosphere, mesosphere.
