Which type of rock is formed when hot lava cools?

• coal

• igneous

• limestone

• metamorphic

Rocks are classified as igneous, sedimentary, or metamorphic based primarily on their

• texture

• crystal or grain size

• method of formation

• mineral composition

How are rocks and minerals related?

• They look alike.

• They are the same thing.

• Minerals are made of rocks.

• Rocks are made of minerals.

Which type of rock forms under high temperatures and pressure but is not exposed to enough heat to melt?

• igneous

• metamorphic

• sedimentary

• volcanic

Base your answer to the following question on the cross section of two crustal plates and the boundary between them shown below. The arrows indicate the direction of rock movement. The mid-oceanic ridge portion of this cross section best represents

• convergence of the Nazca Plate and the South American Plate

• divergence of the African Plate and the South American Plate

• subduction of the Philippine Plate by the China Plate

• transform faulting between the Pacific Plate and the North American Plate
