Rocks and Minerals

QuestionAnswer

Minerals come from what kind of materials non-living
Luster how light is reflected from a mineral's surface
The thinnest layer of Earth crust
If a mineral has volume and shape is a solid
The hardest known mineral diamond
Metamorphic rock comes from where inside the Earth
Rock that cools too quickly to form any minerals are glass
Dissolved minerals glue compacting sediment together cementation
List some stages in the rock cycle weathering and erosion, deposition, melting, volcanic activity, heat and pressure
Crystals that form from rapid cooling lava that forms near the Earth's surface have what size crystals small
Extrusive rock igneous rock that formed from lava that erupted onto Earth's surface
sediment that settles out of water or wind into layers deposition
rocks broken down by freezing and thawing weathering
rock that forms from heat and pressure buried below the surface metamorphic rock
