What is magma?
Melted rock under the Earth's crust
What is the relationship between magma and lava?
Lava is magma that has reached the surface.
What size crystals form when magma cools rapidly?
small crystals
What is a geode?
a rounded, hollow rock that is often lined with mineral crystals
How are veins formed?
formed by solutions of hot water and metals which often flow through cracks in the rock
What is crystallization?
The process by which atoms are arranged to form a material with crystal structure.
What is a solution?
A mixture in which one substance is dissolved in another
How is a geode formed?
a mineral solution seeps into a crack or hollow rock, then crystallizes as it cools.
Does magma that cools slower have bigger or smaller crystals?
bigger
What is one way minerals can form?
Crystallization of materials dissolved in water/ Crystallization of molten material
How do halite deposits form?
Halite deposits form when sea water slowly evaporates.
Granite has coarse-sized grains. Did it form from magma that cooled quickly or slowly?
slowly
In what type of environment do minerals crystallize from evaporated water?
Warm, shallow water in hot, arid regions
Where do large mineral crystals form from magma?
In magma chambers and conduits beneath Earth's surface
