Cleavage is a property of minerals that tells

• how the mineral reflects light

• color of the mineral left behind when it is rubbed on a hard surface

• the way the mineral breaks

• how well the mineral resists being scratched

The way a mineral reflects light is its

• streak

• hardness

• cleavage

• luster

This type of Igneous Rock forms when magma pushes through cracks and becomes trapped, it cools slowly and has large crystals

• Intrusive Rock

• Extrusive Rock

Extrusive rock forms when

• magma becomes trapped and cools slowly over several centuries

• sediments pile up and squeeze together

• lava cools and hardens quickly

• heat and pressure changes a rock
