What is the primary cause of earthquakes?

• Volcanic eruptions

• Movement of tectonic plates along faults

How do earthquakes create tsunamis?

• Earthquakes create tsunamis by volcanic eruptions

• Earthquakes create tsunamis by altering the Earth's rotation

• Earthquakes create tsunamis due to high tides

• Pyroclastic flows are slow-moving currents of cold gas and volcanic matter.

• Pyroclastic flows are a type of cloud formation in the atmosphere.

How do volcanic eruptions affect the environment?

• Volcanic eruptions have no impact on the environment

• Volcanic eruptions only affect the environment positively

• Volcanic eruptions can affect the environment by releasing ash, gases, and lava that can lead to air pollution, acid rain, global cooling, transportation disruption, crop damage, and harm to wildlife.
