Metamorphic Rocks and Processes

Front

Geologists have classified rocks into three major groups of rocks which are:

Back

igneous, sedimentary and metamorphic rocks

Front

Each rock type can follow only one pathway of the rock cycle.

Back

False

Front

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

Back

metamorphic rock

Front

The best answer for section "A" in the diagram: metamorphic process due to increased pressure + temperature, sedimentary process due to compaction + cementation, sedimentary process of weathering + erosion, Igneous process from melting a preexisting rock

Back

sedimentary process of weathering + erosion

Front

The best answer for section "B" in the diagram: metamorphic process due to increased pressure + temperature, sedimentary process due to compaction + cementation, sedimentary process of weathering + erosion, Igneous process from melting a preexisting rock

Back

sedimentary process due to compaction + cementation

Front

The best answer for section "C" in the diagram

metamorphic process due to increased pressure + temperature

Front

The best answer for section "D" in the diagram

Back

Igneous process from melting a preexisting rock

Front

You find a rock in which the grains are arranged in wavy, parallel bands of white and black crystals. What kind of rock have you probably found?

Back

metamorphic gneiss

Front

What will happen if an igneous rock is put under an extreme amount of heat and pressure?

Back

it will become a metamorphic rock

Front

Rock that forms when pressure, temperature, or chemical processes change existing rock.
