Rock Formation and Types Assessment

The video explains the rock cycle, detailing how igneous, sedimentary, and metamorphic rocks form and transform over time. It covers the processes of erosion, weathering, and tectonic activity, emphasizing the continuous nature of the rock cycle and how rocks can change forms through heat, pressure, and other natural forces.

What is the primary process that allows rocks to be continuously formed, worn down, and reformed?

• The Nitrogen Cycle

• The Carbon Cycle

• The Rock Cycle

• The Water Cycle

What type of rock is formed when molten magma cools and solidifies?

• Igneous Rock

• Metamorphic Rock

• Fossil Rock

• Sedimentary Rock

Which type of igneous rock is formed when magma cools slowly beneath the Earth's surface?

• Metamorphic Rock

• Intrusive Igneous Rock

• Extrusive Igneous Rock

• Sedimentary Rock

How are sedimentary rocks primarily formed?

• By the accumulation and cementation of sediments

• Through volcanic eruptions

• By the cooling of magma

• Through the melting of rocks

What is a common characteristic of sedimentary rocks?

• They are always found deep underground

• They are formed from magma

• They often contain fossils

• They contain large crystals

What causes metamorphic rocks to form?

• Erosion by wind and water

• Heat and pressure

• Accumulation of sediments

• Cooling of lava

Which rock type can transform into marble under heat and pressure?

• Granite

• Limestone

• Sandstone

• Shale

What is the main agent of erosion in dry desert-like areas?

• Ice

• Wind

• Water

• Chemical reactions

What role do tectonic plates play in the rock cycle?

• They cause rocks to melt into magma

• They only affect sedimentary rocks

• They prevent rocks from changing form

• They have no effect on the rock cycle

What is the effect of acid rain on certain rocks?

• It has no effect

• It turns them into igneous rocks

• It dissolves them

• It strengthens them
