Volcanic Eruptions

What is a volcano?

• A volcano is a type of cloud formation

• A volcano is a type of rock found in the ocean

• A volcano is a type of bird known for its colorful feathers

• A volcano is a rupture in the crust of a planetary-mass object that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

How are volcanoes formed?

• Magma from within the Earth's mantle rises to the surface.

• Volcanoes are man-made structures

• Volcanoes are formed by meteor impacts

• Volcanoes are created by underground rivers

How do scientists monitor volcanic activity?

• Analyzing cloud formations

• Observing animal behavior

• Using thermometers and barometers

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

What is the difference between lava and magma?

• Magma is hotter than lava.

• Lava flows on the surface, magma is beneath the surface.

• Lava is solid, magma is liquid.

• Lava is found in the Earth's core, magma on the surface.

What is pyroclastic flow?

• A pyroclastic flow is a slow-moving current of cold gas and volcanic matter that flows up the slope of a volcano during an eruption.

• A pyroclastic flow is a geological term for the process of magma solidifying into rock.

• A pyroclastic flow is a type of cloud formation that occurs after a volcanic eruption.

• A pyroclastic flow is a fast-moving current of hot gas and volcanic matter that flows down the slope of a volcano during an eruption.

How do volcanic eruptions affect the environment?

• Volcanic eruptions reduce global warming

• Volcanic eruptions affect the environment by releasing ash, gases, and lava which can lead to air pollution, acid rain, and changes in climate.

• Volcanic eruptions lead to increased biodiversity

• Volcanic eruptions have no impact on the environment
