Across
- 4. -rocks melt into magma / lava -magma / lava cools down and crystallizes into minerals -different crystals form at different temperatures as it cools down
- 7. Uncommon mineral group. They always contain one Molybdenum atom attached to 4 Oxygen atoms. Color: red, orange, yellow, silver, white Luster: vitreous (glassy) Streak: white Cleavage: breaks clean Hardness (Moh’s Hardness Scale): mid (3-4)
- 8. Uncommon mineral group. They always contain one Tungsten atom attached to 4 Oxygen atoms. Color: greyish color Luster: shiny Streak: white Cleavage: breaks in square edges Hardness (Moh’s Hardness Scale): mid (4-5)
- 9. When minerals form quickly, crystals solidify fast and end up SMALL. When minerals form slowly, crystals solidify slowly and end up LARGE.
- 10. Deposits that are created when a mineral solution seeps into cracks in a rock. The solution cools down and forms minerals in the cracks.
Down
- 1. -a substance is dissolved in a solution -solution evaporates -crystals form as the water evaporates
- 2. Common mineral group. They always contain one Nitrogen atom attached to 3 Oxygen atoms. Color: white to grey Luster: vitreous (glassy) Streak: white Cleavage: clean break Hardness (Moh’s Hardness Scale): low (1-2)
- 3. Rare mineral group. Forms when Oxygen combines with Vanadate. Color: bright colors (yellow, blue, green, purple) Luster: resinous (waxy) Streak: brown or yellow Cleavage: brittle Hardness (Moh’s Hardness Scale): mid (3-4)
- 5. Rare mineral group. Forms when Oxygen combines with Arsenic. Color: white, grey, black Luster: metallic to non-metallic (dull) Streak: yellow Cleavage: clean break Hardness (Moh’s Hardness Scale): mid (3-4)
- 6. -magma heat up water from underground -substances dissolve in the water -solution flows into cracks, cools, down, crystals form
