Question

1c. in your own words, describe the characteristics of the three types of rocks.
write your answer here...

Explanation:

• Igneous rocks: Formed from cooled magma/lava. Have crystalline texture. Examples: granite (intrusive), basalt (extrusive).
• Sedimentary rocks: Formed from sediment compaction/cementation. Often layered. Examples: sandstone (clastic), limestone (chemical/organic).
• Metamorphic rocks: Formed from existing rocks under heat/pressure. Show foliation or non - foliation. Examples: slate (foliated), marble (non - foliated).

Answer:

Igneous rocks form from cooled magma/lava with a crystalline texture (e.g., granite, basalt). Sedimentary rocks form from sediment compaction/cementation, often layered (e.g., sandstone, limestone). Metamorphic rocks form from existing rocks under heat/pressure, showing foliation or non - foliation (e.g., slate, marble).
