Answer 2

Explanation:

• Igneous rocks are formed when melted lava or magma cools and crystallizes, and their unique traits are based on this process. They are strong because their mineral grains grow together tightly as they cool, and their minerals are usually black, white, or gray.
• These atoms and molecule rearrange themselves into mineral grains as the magma cools, forming rock as the mineral grains grow together. There are over 700 different types of igneous rocks.
• Igneous rocks can be intrusive or extrusive, depending upon how the rocks are formed. Intrusive or plutonic rocks (e.g., granite) are directly formed from the magma and cooling process occurs below the earth's surface. Extrusive or volcanic rocks (e.g., basalt) are formed after solidification of lava.
