Rocks and Minerals Post Test Review

As a quartz pebble is transported by a stream, the pebble will become more rounded as a result of...

• resistance to weathering and erosion

• dissolving as water is running over the rock

• abrasion by colliding with other rocks

• deposition in well-sorted layers

Metamorphic rocks form because of

• Heat and Pressure

• Gravity

• Magnetic Fields

• Lava

Magma that cools slowly forms ________________ rocks.

• Extrusive Metamorphic

• Intrusive Metamorphic

• Intrusive Igneous

• Extrusive Igneous

Extrusive igneous rocks formed _________________.

• outside the earth's surface

• when metamorphic rocks became magma

• magma stayed inside the earth

• sediments got cemented together

All of the following are things that happen during the rock cycle EXCEPT

• Heat and pressure can turn metamorphic rock into sedimentary rock

• Melting causes sedimentary rocks to turn into magma

• Weathering and erosion can cause igneous rocks to turn into sediments

• Through compaction and cementation sediments can turn into sedimentary rocks

What can happen to igneous rocks when introduced to heat and pressure?

• Melts and turn into lava

• Turns into metamorphic rocks

• The igneous rocks turn into sediments

• It turns into sedimentary rocks

Which is the first step for a fossil to form?

• Rock hardens and form a fossil

• Animal dies and have to be quickly buried.

• Minerals fill the mold to form a cast fossil

• Water dissolves the soft parts leaving a fossil mold.
