Answer

### B. Warm air cools as it mixes with cooler, denser air

Explanation

## Step 1: Understand Convection### Convection is the process of heat transfer through fluid motion (liquid or gas). Warmer, less dense fluid rises, and cooler, denser fluid sinks.## Step 2: Identify Relevant Process### Warm air rises because it is less dense. As the warm air moves upwards, cooler and denser air moves in to take its place.## Step 3: Match Description with Option### Option B "Warm air cools as it mixes with cooler, denser air" best matches this process.
