Volcano Morphology Quiz

What is a volcanic eruption?

• A volcanic eruption is caused by the movement of tectonic plates

• A volcanic eruption is the ejection of rock, ash, and lava from a volcano

• A volcanic eruption is the result of heavy rainfall in a volcanic area

• A volcanic eruption is the release of hot air from a volcano

How are volcanoes classified?

• Based on their smell and taste

• Based on their location and age

• Based on their eruption style, shape, and type of lava they produce.

• Based on their color and size

What are the three types of volcanic cones?

• shield, cinder, and composite cones

• triangle, square, circle

• pine, oak, maple

• rock, paper, scissors

What causes a volcanic eruption?

• Alien invasion

• Global warming

• Release of magma from beneath the Earth's crust

• Heavy rainfall

Explain the difference between shield, cinder, and composite volcanoes.

• Shield volcanoes have steep slopes and are formed by the eruption of explosive lava

• Composite volcanoes have gentle slopes and are formed by the eruption of low-viscosity lava

• The correct answer is that shield volcanoes have gentle slopes and are formed by the eruption of low-viscosity lava, cinder volcanoes have steep slopes and are formed by the eruption of explosive lava, and composite volcanoes have a combination of both gentle and steep slopes and are formed by alternating eruptions of lava and ash.

• Cinder volcanoes have gentle slopes and are formed by the eruption of low-viscosity lava

What are the main components of a volcanic eruption?

• water, rocks, and steam

• magma, gases, and volcanic ash

• lava, smoke, and dust

• fire, ice, and snow

Describe the structure of a volcanic cone.

• It is typically made up of layers of lava, ash, and other volcanic debris.

• It is made of solid gold and diamonds

• It is composed of layers of chocolate and marshmallows

• It is built with bricks and mortar

What are the dangers associated with volcanic eruptions?

• The dangers associated with volcanic eruptions include lava flows, ashfall, pyroclastic flows, lahars, and volcanic gases.

• Earthquakes

• Hurricanes

• Tornadoes

How do scientists monitor volcanic activity?

• Using seismometers, gas sensors, satellite imagery, and ground deformation measurements

• Relying on astrological signs

• By observing animal behavior

• Using weather balloons

Explain the process of volcanic ash formation.

• During explosive volcanic eruptions, fragmented magma and rock are ejected into the atmosphere, which then cools and solidifies to form volcanic ash.

• Volcanic ash is the result of lava cooling down

• Volcanic ash is created by the erosion of volcanic rocks

• Volcanic ash is formed by the accumulation of dust in the atmosphere
