This rock is formed from magma cooling into a solid. (Think rocks found in an igneous intrusion)

• Intrusive Igneous Rock

• Metamorphic Rock

• Sedimentary Rock

• Extrusive Igneous Rock

Answer explanation

INtrusive igneous rocks are found INside of Earth's surface. EXtrusive igneous rocks are found after the lava EXited Earth's surface.

When Joe saw the Rocky Mountains for the first time, he exclaimed, "These mountains are much younger than our Great Smoky Mountains!" Which feature supports his conclusion that the Rockies were relatively young mountains?

• Their sedimentary layers are still exposed

• They have rounded tops

• They have sharp peaks

• Weathering has not yet hardened the rock

Answer explanation

The longer that mountains are exposed to wind and rain, the more their peaks have been eroded away, causing them to be rounder.

This rock was formed by lots of fossils that settled on top of each other over time. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

Answer explanation

Only sedimentary rocks can have fossils. Metamorphic rocks cannot have fossils since the heat and pressure would have destroyed them. Igneous rocks cannot have fossils since the melting and cooling would have destroyed them.

• Igneous Rock

• Metamorphic Rock

• Sedimentary Rock

• Classic Rock

Answer explanation

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic

Answer explanation

This rock was formed from smaller bits of rocks (sediments) being compacted and cemented together. That is how sedimentary rocks can form.

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

• Sedimentary
• Igneous
• Metamorphic
