Rock Cycle, Earth's Surface, Weather

Geologists have classified rocks into three (3) major groups of rocks. These are called:

• Inorganic, organic, and chemical rocks

• Igneous, sedimentary and metamorphic rocks

• Metamorphic, chemical and non chemical rocks

• Sedimentary, inorganic and igneous rocks

Any rock that forms from another rock as a result of changes in heat or pressure (or both) is a:

• Chemical rock

• Igneous rock

• Sedimentary rock

• Metamorphic rock

If heat and pressure inside the Earth cause the texture and crystal structure of a rock to change, what type of rock is formed?

• Sedimentary rock

• Metamorphic rock

• Igneous rock

• Chemical rock

The process when rocks break into smaller pieces due to exposure to natural elements is called:

• Erosion

• Weathering

• Sedimentation

NGSS.MS-ESS2-2

This rock was formed by smaller fragments of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

• Sedimentary

• Igneous

• Metamorphic

NGSS.MS-ESS1-4

Which rock is formed from the cooling of lava on Earth's surface?

• Intrusive igneous

• Foliated metamorphic

• Extrusive igneous

• Organic sedimentary

Rocks that form from magma cooling inside the Earth are called:

• Intrusive igneous

• Extrusive igneous

• Foliated metamorphic

• Non-foliated metamorphic

True/False: Igneous rocks can only turn into metamorphic rocks.

• True
• False

The continuous process of rock changing from one type to another is called:

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• The Rock Cycle

Limestone is a sedimentary rock. During the rock cycle, limestone is changed into marble, a metamorphic rock. The processes that act on limestone and change it into marble are:

• Weathering and erosion

• Heat and pressure

• Compaction and cementation

• Melting and cooling
