Volcanoes and Topographic Maps Quiz

What is a volcano?

• A mountain with a crater at the top

• An opening on the Earth's crust from where molten lava, rocks, and natural gases come out

• A type of storm with lightning and thunder

• A large body of saltwater

How are volcano shapes formed?

• By the accumulation of snow

• When tectonic plates shift or when the ocean plate sinks

• Through the erosion of rocks by wind and water

• By the movement of glaciers

What is released from the Earth's surface when a volcano erupts?

• Ice, snow, and cold air

• Sand, dust, and dry leaves

• Molten rock, ash, and lava

• Water, steam, and mud

What is a composite volcano?

• A mountain formed by the accumulation of rock debris

• A cone-shaped volcano built from several layers of lava, pumice, and ash

• A flat area of land created by river deposits

• A steep-sided volcano formed from a single layer of rock

What shape do composite volcanoes tend to form?

• Rounded cones

• Tall peaks

• Wide plateaus

• Deep valleys

What is a characteristic feature of shield volcanoes?

• They have steep inclining sides.

• They are small in size.

• They have shallow inclining sides.

• They are formed from magma flows of high thickness.

How are shield volcanoes formed?

• From magma flows of high thickness.

• From the rapid cooling of lava.

• From magma flows of low thickness.

• From the accumulation of ash and debris.

What characterizes a cinder cone volcano?

• A wide base and large size

• A plateau shape and accumulation of ice

• A cone shape, steep slope, and small size

• A dome shape and large eruptions

How are cinder cone volcanoes formed?

• By the cooling of lava on the earth's surface

• By the accumulation of ejected rocks from the volcanoes that form the slopes

• By the movement of tectonic plates

• By the erosion of larger volcanoes

what type of volcano is this?

• composite or strato volcano

• shield volcano

• cinder cone volcano

• all of the above
