Question

Arrange the events of succession after a volcano erupted in their proper order.

A) Lava flow, pyroclastic flow, ashfall, volcanic gases release.
B) Ashfall, pyroclastic flow, volcanic gases release, lava flow.
C) Pyroclastic flow, ashfall, volcanic gases release, lava flow.
D) Volcanic gases release, ashfall, lava flow, pyroclastic flow.

Answer 1

The proper order of events after a volcano eruption is ashfall, pyroclastic flow, volcanic gases release, and lava flow.

Step-by-step explanation:

The proper order of events of succession after a volcano erupted is:

1. Ashfall: The eruption releases ash into the air, which falls and blankets the area.
2. Pyroclastic flow: A rapid-moving, dense, and hot mass of gas and rock flows down from the volcano, knocking down structures and altering the landscape.
3. Volcanic gases release: Gases such as carbon dioxide, sulfur dioxide, and water vapor are released during the eruption.
4. Lava flow: Molten rock flows out of the volcano and hardens into rock as it cools.
