7. Igneous Rocks are formed from cooled magma or lava.

8. Igneous Rocks Mount Rushmore (made of granite) Stone Mountain, GA

9. Igneous Rocks Black Sand Beach at Waianapanapa State Park, Hawaii
The black sand that forms the beach comes from volcanic rock, gradually pulverized over thousands of years by the incessant wave action at the shore. Much of the sand is actually very tiny pebbles of BASALT.

14. Canyonlands National Park, Utah The Needles District forms the southeast corner of Canyonlands and was named for the colorful spires of Cedar Mesa Sandstone that dominate the area.

15. Bryce Canyon National Park

17. Metamorphic rocks form in places that are under very high pressure and/or have a high temperature, such as at convergent boundaries.

18. Metamorphic Rocks North Cascade Mountains Washington State

19. Metamorphic Rocks Cascade Mountains
Ruby Mountain > Rocks on the summit are fine-grained amphibolite (metamorphosed basalt) and mica quartz schist (metamorphosed chert), as well as pods of ultramafic rock (metamorphosed mantle), commonly colored red-orange by weathering.
