Rocks

Which of the following will most likely increase the amount of erosion that occurs on the banks of a river?

• Heavy rains on the mountain that is the river’s water source

• High winds over the ocean to which the river flows

• High temperatures increasing evaporation from the river

• Ice formation at the source of the river

Igneous rocks and metamorphic rocks have similar formation, in that they both –

• require extreme heat.

• always form from sediments.

• cool to form distinct layers.

• often contain fossil organisms.

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.

• seasonal patterns change the rate of erosion.

• 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.

In order for a rock to be classified as igneous, what must have happened during its formation?

• Solid rock changing under pressure

• Liquid rock changing its physical state

• Small rocks becoming cemented together

• Layered rock breaking into smaller pieces

Sedimentary rock can be changed into igneous rock if sediments are –

• compacted.

• deposited.

• weathered.

• melted.

Igneous and sedimentary rocks could each be changed into metamorphic rock if they are changed by -

• weathering.

• organisms.

• pressure.

• cementation.
