Volcanoes Quiz

What is a volcano?

• A mountain formed by hot molten rock from deep inside the Earth

• A mild acid that finds its way to the surface

• A type of lava that flows quickly down the sides of a volcano

• A type of rock that is formed when lava cools off

How do volcanoes form?

• When lava solidifies and forms new land

• When sodium bicarbonate is added to mild acid

• When tectonic plates collide

• When hot molten rock from deep inside the Earth reaches the surface

What are the different types of volcanoes?

• Magma, lava, and pumice

• Pahoehoe, ah, and tephra

• Molten rock, magma plume, and volcanic ash

• Shield, cinder cone, and strata cone

How do shield volcanoes form?

• Explosive cinder ash erupts from the volcano

• Lava and ash spew out alternately

• Magma plume finds its way to the surface through cracks in the plate

• Hot lava flows quickly down the sides of the volcano

What is a stone wind?

• A wind that blows from the direction of a volcano

• A wind that cools down the lava and forms new land

• A wind loaded with pumice volcanic ash

• A wind that carries seeds to volcanic landscapes

What is the difference between dormant and extinct volcanoes?

• Dormant volcanoes have recently erupted, while extinct volcanoes haven't erupted in millions of years

• Dormant volcanoes have cooled magma plumes, while extinct volcanoes have active magma chambers

• Dormant volcanoes are sleeping and may erupt again, while extinct volcanoes will never erupt again

• Dormant volcanoes are smaller than extinct volcanoes

What is the temperature of lava?

• Around a hundred degrees Celsius

• Over a thousand degrees Celsius

• Around five hundred degrees Celsius

• Around three hundred degrees Celsius

What is the purpose of studying volcanoes?

• To measure airborne particle levels

• To predict when volcanoes will erupt

• To understand the Earth's history and how land is formed

• To build houses on volcanic landscapes

What is the main feature of volcanoes?

• Their lava flows

• Their explosive eruptions

• Their ability to form new land

• Their unpredictability

What is a caldera?

• A type of lava tube formed underground

• A large bowl-shaped depression formed by the collapse of a volcano

• A volcanic rock that is rich in gas

• A chamber of magma deep inside the Earth
