The video explains the classification of rocks into three main types based on their formation: sedimentary, metamorphic, and ichnia rocks. Sedimentary rocks form from compressed sediment, with limestone as an example. Metamorphic rocks result from heat and pressure, transforming limestone into marble. Ichnia rocks form from cooled magma, either underground or from volcanic eruptions, and are used in construction.

What process leads to the formation of sedimentary rocks?

• Cooling of magma

• Compression of sediment layers

• Melting of rocks

• Erosion by wind

Which of the following is an example of sedimentary rock?

• Basalt

• Granite

• Marble

• Limestone

How does limestone transform into marble?

• Through cooling

• By compression

• Under heat and pressure

• By erosion

What is the primary characteristic of igneous rocks?

• They are formed by sediment compression

• They are known for their toughness

• They are formed by erosion

• They are used in glass making

What happens to magma when it cools and solidifies?

• It becomes sedimentary rock

• It erodes into sand

• It turns into marble

• It forms igneous rock
