1. What are the different properties of minerals?
answer: Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
2. What are rocks made of?
answer: To geologists, a rock is a natural substance composed of solid crystals of different minerals that have been fused together into a solid lump.
3. Why are minerals important?
answer: Minerals are important for your body to stay healthy
4. How are rocks formed?
answer: such as melting, cooling, eroding, compacting, or deforming
5. What is chemical weathering?
answer: the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.
6. What is mechanical weathering?
answer: Mechanical weathering (also called physical weathering) breaks rocks into smaller pieces. These smaller pieces are just like the bigger rock, just smaller.
7. What is erosion? (3 points)
answer: Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water
8. What are the different agents of erosion?
answer: The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity
9. What are the different layers of a soil profile or soil horizon?
answer: the surface horizon (A), the subsoil (B), and the substratum (C).
10. What are the different farming practices?
answers: proper soil preparation, planting or sowing of crops, plant care management, harvest, and post-harvest management.
