Question
The volcano erupts with basic lava, spilling primarily
- Ash
- CO
- Dust
- Oxygen
Hint:
Ash
The correct answer is: Ash
Running Magma erupts through openings or vents in the earth's crust before flowing onto its surface as lava causing volcanoes to erupt. Volcanoes spew hot, dangerous gases, ash, lava and rock that are powerfully destructive. People have died from volcanic blasts. Volcanic eruptions can result in additional threats to health, such as floods, mud slides, power outages, drinking water contamination and wildfires.
