• metamorphic
• sedimentary
• intrusive igneous
• extrusive igneous
• magma

The process by which larger rocks are broken up into smaller rock pieces and particles is called

• sedimentation.
• erosion.
• weathering.
• deposition.

The process by which soil and rock particles are moved by wind, water or ice is called

• sedimentation.
• erosion.
• weathering.
• deposition.

Igneous rocks

• form from the cooling of molten material called magma.
• form when small particles of rocks are cemented together.
• form when a rock is changed by heat and pressure.
• form when larger rocks are broken up into smaller pieces.

_______________ are made up of fragments of weathered rock that have been eroded, deposited into layers, and cemented together.

• Chemical sedimentary rocks
• Clastic sedimentary rocks
• Organic sedimentary rocks

_______________ are made of the remains of plants and animals.

• Chemical sedimentary rocks
• Clastic sedimentary rocks
• Organic sedimentary rocks

_______________ form when minerals that are dissolved in water are left behind when the water evaporates.

• Chemical sedimentary rocks
• Clastic sedimentary rocks
• Organic sedimentary rocks

Coal is a (an) _______________ because it is formed when dead plants are buried for hundreds of millions of years.

• chemical sedimentary rocks
• clastic sedimentary rocks
• organic sedimentary rocks

Sandstone is a (an) _______________ because it is often formed when weathered sand particles are washed away, are piled up at the bottom of a lake or the mouth of a river, and become cemented together.

• chemical sedimentary rocks
• clastic sedimentary rocks
• organic sedimentary rocks

Petrified fossils, such as petrified wood, are _______________ because they form when water containing dissolved minerals soaks into dead plant and animal cells. The water eventually evaporates, leaving the minerals behind.
