Question
Possible Points: 1
When volcanoes erupt, they emit large plumes of hot smoke and ash, which can spread and cover miles of sky. Which process lifts the hot, black clouds into the sky?
Responses

convection that causes warmer air to rise and cooler air to sink into its place
convection that causes warmer air to rise and cooler air to sink into its place

conduction that causes warmer air to spread and cooler air to condense into clouds
conduction that causes warmer air to spread and cooler air to condense into clouds

conduction that causes thermal energy to pass from the smoke into the ground
conduction that causes thermal energy to pass from the smoke into the ground

radiation that causes thermal energy to transfer into the clouds and hold them together

Answer 1

The correct response is:

**convection that causes warmer air to rise and cooler air to sink into its place.**

This process explains how the hot smoke and ash are lifted into the sky during a volcanic eruption. Warmer air is less dense and rises, while cooler air moves in to take its place, which creates a convective current.
