Rocks and Minerals Warmups

Ricardo has an igneous rock in his rock collection. Where did this rock most likely form?

• in a volcano
• on a forest floor
• on a coral reef
• at the bottom of a river

Cleavage of a mineral is related to a mineral's

• chemical composition
• streak color
• luster
• crystalline structure

Which kind of rock is formed when volcanic lava cools?

• sedimentary
• metamorphic
• igneous
• magma

A student wants to study how igneous rock changes to sedimentary rock. Is this a good project if the student needs to complete the study within a month. 

• Yes because the changes will happen quickly and be significant.
• Yes because the changes will be easily observed since they are very obvious.
• No because the difference between igneous rock and sedimentary rock is not noticeable.
• No because the changes will take much longer than a month to occur.

Sedimentary rocks are not found on the Moon because

• there is no silicon on the Moon.
• lava flows are missing from the surface.
• the Moon's gravity is too weak.
• there is no weathering on the Moon.

Rocks found on Earth are generally classified as sedimentary, metamorphic, or igneous. On which basis are these classifications made?

• where the rocks are found
• how the rocks were formed
• the color and shape of the rocks
• the chemical composition of the rocks

The formation of metamorphic rocks depends on all of the following except

• the composition of the parent rocks
• Earth's magnetic field
•  temperature.
• pressure.

When rocks undergo weathering, they become

• magma
• igneous rocks
• sediment
•  volcanic cones

Sedimentary rocks can be converted into magma by undergoing which of the following processes?

• weathering and erosion
• cooling and crystallization
• heat and pressure
• compaction and cementation

What type of rock results from the cooling of lava from a volcano?

• sedimentary
• bituminous
• igneous
• metamorphic
