What are the three types of rock categories?

• Igneous, Obsidian, and Lava-formed

• Shale, Diamond, and Fossils

• Igneous, Sedimentary, and Metamorphic

• Sedimentary, Shale, and Crushed

Which rock type is formed from the cooling and solidification of magma or lava?

• Sedimentary

• Metamorphic

• Igneous

• Shale

What process is primarily responsible for the formation of sedimentary rocks?

• Crystallization

• Deposition, compaction, and cementation

• Metamorphism

• Melting and solidification

Which type of rock is typically formed by the alteration of pre-existing rocks under the influence of high pressure, high temperature, or both?

• Igneous

• Sedimentary

• Metamorphic

• Lava-formed

Extrusive rocks are formed ​ (a)   from lava, while intrusive rocks are formed​ (b)   by magma.

• on the surface
• under ground
• poorly
• well
• metamorphic
• sedimentary

The sedimentary process makes rocks from sediments of dead plants, other rocks, and bones. Put the process in the correct order:

• Step 4

• Weathering (Breaking down into sediment)

• Step 2

• Compaction (Squeezing sediment tightly)

• Step 1

• Cementation (Sediments turn into rock)

• Step 5

• Sedimentation (Bringing sediments together)

• Step 3

• Erosion (Moving sediment)

When lava cools quickly, does it create minerals that are large or small?

What is the main agent involved in the metamorphism of rocks?

• Water

• Wind

• Heat and pressure

• Ice

Jack thinks rocks can't be changed from one type to another. Sarah thinks they can. Who is correct? Can you explain why?

What are the three properties of a mineral?

• Shinyness, Strength, and Drop-ability

• Lustre, Hardness, and Streak

• Reflectiveness, Composition, and Depth
