What are the three main types of volcanoes?

• big volcanoes, small volcanoes, and medium-sized volcanoes

• hot volcanoes, cold volcanoes, and lukewarm volcanoes

• shield volcanoes, cinder cone volcanoes, and composite volcanoes

• round volcanoes, square volcanoes, and triangular volcanoes

What is the difference between a shield volcano and a stratovolcano?

• The difference is in their height and the surrounding landscape

• The difference is in their location and the type of rocks they produce

• The difference is in their slopes and the viscosity of the lava erupted.

• The difference is in their color and the number of eruptions

What is a volcanic eruption?

• The release of magma, ash, and gases from a volcano

• The release of snow and ice from a mountain

• The eruption of water from a geyser

• The explosion of a nuclear bomb

How do scientists monitor volcanic activity?

• Seismometers, gas sensors, satellite imagery, and ground deformation measurements

• Compasses and telescopes

• Weather balloons and radar

• Thermometers and barometers

What are some signs that indicate a volcanic eruption might occur?

• No changes in gas emissions and no earthquakes near the volcano

• Increased seismic activity, ground deformation, changes in gas emissions, and small earthquakes near the volcano

• Decreased seismic activity and ground deformation

• Increased rainfall and clear skies

What is the Ring of Fire?

• A type of jewelry worn by rock stars

• A popular song by Johnny Cash

• A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur

• A nickname for a professional wrestler

How do volcanic eruptions affect the environment?

• Volcanic eruptions have no impact on the environment

• Volcanic eruptions create a healthier atmosphere

• Volcanic eruptions have a positive effect on climate change

• Volcanic eruptions can affect the environment by releasing harmful gases, causing air pollution, and altering the climate.

What is the main cause of a volcanic eruption?

• The release of snow and ice from a mountain

• The eruption of water from a geyser

• The release of magma, ash, and gases from a volcano

How are shield volcanoes different from cinder cone volcanoes?

• The difference is in their height and the surrounding landscape

• The difference is in their location and the type of rocks they produce

• The difference is in their slopes and the viscosity of the lava erupted.

• The difference is in their color and the number of eruptions
