NGSS.MS-ESS2-2

After lots of time, pressure, and heat, you get this kind of rock. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

This rock was found near the mouth of a volcano. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

This rock cooled on the outside of a volcano and contained air bubbles when it was forming. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

Igneous rock forms in regions where--

• A rock is heated to melting point then cooled to a solid.
• Metallic minerals are put under extreme pressure.
• A river deposits sand and mud over a long time.
• Evidence of organisms is becoming fossilized.

Sedimentary rocks will most likely form an environment where--

• Two land masses are colliding.
• Liquid rock is hardening into a solid.
• Minerals are being created under pressure.
• Particles of rocks are accumulating.
