What terms can be used to describe luster? metallic, glassy, earthy, silky, waxy, and pearly
What is streak? streak of a mineral is the color of its POWDER. the color of a mineral can vary, the streak does not.

What are some minerals formed in solutions and by evaporation? halite, calcite, and gypsum
What are some minerals formed as lava cools? pyroxene and olivine
What are some minerals formed as magma cools? quartz and feldspar
What determines crystal size in minerals formed by lava or magma? The rate at which the minerals cooled
What determines the size of a crystal? the rate at which the melted rock cools- the slower the cooling leads to large crystals while the faster it cools leads to small crystal
What is graphite made of? carbon
