Question

match each type of rock to its description:
igneous choose
choose
sedimentary formed when sediment is compacted and cemented together
formed when heat and pressure change existing rock
formed when molten rock cools and solidifies
metamorphic choose

Explanation:

• Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava). So Igneous matches "Formed when molten rock cools and solidifies".
• Sedimentary rocks are formed by the compaction and cementation of sediment (like sand, mud, etc.). So Sedimentary matches "Formed when sediment is compacted and cemented together".
• Metamorphic rocks are formed when existing rocks are subjected to heat and pressure, causing a change in their structure and composition. So Metamorphic matches "Formed when heat and pressure change existing rock".

Answer:

Igneous: Formed when molten rock cools and solidifies
Sedimentary: Formed when sediment is compacted and cemented together
Metamorphic: Formed when heat and pressure change existing rock
