What Dissolves in the hot water to form solutions
Minerals
What is water heated by
Magma
What leaves the solutions during cooling?
Elements and compounds
What do elements and compounds do when they leave
Crystallize as minerals
The minerals form a long channel or slab in the rock called a
Vein
What are the two ways minerals form
- crystallization of melted materials.
2. crystallization of materials dissolved in water.
How do small crystals form
Fast cooling
How do big crystals form
Slow cooling
How do minerals for pm near ocean ridges
- Water seeps down through cracks in crust.
- water meets magma and cools to high temperature.
- water dissolves minerals from crust rushes up through chimneys.
- when cooled minerals crystallize they settle to the ocean floor
How do halite deposits form
When the ancient seas slowly evaporate
