I WONDER - How Are Volcanic Rocks Made?

The video explains the dangers of volcanic eruptions, focusing on the gases released. It introduces pumice stone, a rock formed when magma cools rapidly, trapping air bubbles inside. This unique formation allows pumice to float on water.

What is one of the hazards of being near an erupting volcano?

• Heavy rainfall

• Earthquakes

• Gases spewing out

• Loud noises

What is pumice stone primarily made from?

• Metamorphic processes

• Sedimentary deposits

• Magma cooling quickly

• Lava cooling slowly

Why does pumice stone have a unique texture?

• It contains trapped air bubbles

• It is formed under high pressure

• It is made from fine sand

• It is polished by water

What characteristic allows pumice stone to float on water?

• Its trapped air bubbles

• Its smooth surface

• Its mineral composition

• Its high density

Which of the following is NOT a feature of pumice stone?

• It contains air bubbles

• It is a type of sedimentary rock

• It is formed from rapidly cooling magma

• It can float on water
