Answer
### 3. Heated air in the lower atmosphere transferred upward by density differences
Explanation
## Step1: Identify the Type of Energy Transfer in Each Option### 1. Electromagnetic energy transferred from the Sun to the Moon - This describes radiation.### 2. Solar energy transferred through space to Earth's surface - This also describes radiation.### 3. Heated air in the lower atmosphere transferred upward by density differences - This describes convection.### 4. Heat from radioactive decay transferred by molecular collisions to surrounding mantle rock - This describes conduction.## Step2: Determine the Method of Convection### Convection involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences.
