The video tutorial explains the different types of rocks: igneous, sedimentary, and metamorphic. It describes how each type is formed, provides examples, and discusses the rock cycle, which illustrates how rocks transform from one type to another over time due to various geological processes.

What are the three main types of rocks?

• Igneous, Sedimentary, and Metamorphic

• Igneous, Sedimentary, and Fossil

• Sedimentary, Metamorphic, and Fossil

• Igneous, Metamorphic, and Organic

How is intrusive igneous rock formed?

• When rocks are exposed to heat and pressure

• When sediment accumulates over time

• When magma cools slowly beneath the Earth's surface

• When lava cools on the Earth's surface

Which of the following is an example of extrusive igneous rock?

• Granite

• Limestone

• Obsidian

• Marble

What is sediment?

• Large rocks found on the Earth's surface

• Rocks that have been changed by heat and pressure

• Small particles of sand, mud, and organic material

• Magma that has cooled

Which type of rock is most likely to contain fossils?

• Volcanic rock

• Sedimentary rock

• Metamorphic rock

• Igneous rock

What does the word 'metamorph' mean?

• To form layers

• To change form

• To erode

• To crystallize

How can metamorphic rocks be formed?

• By erosion due to wind and water

• By being deep under the Earth where pressure and temperatures are high

• By cooling of magma

• By accumulation of sediment

What does shale become when exposed to heat and pressure?

• Slate

• Quartzite

• Granite

• Marble

What is the starting point of the rock cycle?

• Metamorphic rock

• Igneous rock

• Magma

• Sediment

How can sedimentary rocks transform into metamorphic rocks?

• By cooling of magma

• By being exposed to heat and pressure

• By erosion due to wind and water

• By crystallization
