Rock Cycle

Igneous rock forms in regions where

• evidence of organisms is becoming fossilized

• a river deposits sand and mud over a long time

• metallic minerals are put under extreme pressure

• rock is heated to melting point then cooled to a solid

Sedimentary rocks will most likely form an environment where

• two land masses are colliding

• particles of rocks are accumulating

• liquid rock is hardening into a solid

• minerals are being created under pressure

Which of the following processes produce metamorphic rocks?

• rapid burial

• gradual cooling

• regular deposition

• extreme pressure

Scientists classify igneous, metamorphic, and sedimentary rocks based on their

• shape

• color

• formation

• usefulness

Which of the following best describes the processes that form igneous rocks?

• deposition and cementation

• heating and extreme pressure

• crystallization and solidication

• erosion and compaction

Sedimentary rocks can have layers of different colors. This occurs when

• molten rock seeps into large cracks underground.

• extreme pressure causes minerals to separate.

• different minerals are deposited at different times.

• season patterns change the rate of erosion

Which of the following is one of the final processes in the formation of sedimentary rock?

• melting

• cementation

• flowing

• separation

The presence of igneous rocks might be evidence of

• organisms

• deposition

• coal

• volcanoes

Metamorphic rock forms where any kind of rock-

• is crystalized after being liquid rock

• contains fossils of marine organisms

• is changed by the extreme heat and pressure

• is composed of cemented sediment

In order to be classified as metamorphic, a rock must have

• magma cooling underground

• changed with heat and pressure

• compacted sediment into layers

• formed in less than 100 years
