What is Metamorphic Rock?
300
This is a description of an Igneous Rock.
What is a rock that can have gas bubbles, can be glossy, can be coarse-grained, and does not contain fossils?
300
This type of volcano erupts violently; hot ashes, cinders, and volcanic bombs fly into the air; has stick lava, and wears away easily.
What is a Cinder Cone?

What is a plate boundary?

What is 1,000+ years?
