What is the primary mode of heat transfer from the Sun to the Earth?

What is the primary mode of heat transfer from the Sun to the Earth?

Step 1: Understand that the Sun is a very hot star that produces energy.
Step 2: Know that energy from the Sun travels through space to reach the Earth.
Step 3: Learn that there are three main ways heat can transfer: conduction, convection, and radiation.
Step 4: Realize that conduction requires direct contact and convection requires a medium like air or water.
Step 5: Understand that space is a vacuum, meaning there is no air or matter for conduction or convection.
Step 6: Conclude that the only way heat can travel through the vacuum of space is by radiation.
Step 7: Therefore, the primary mode of heat transfer from the Sun to the Earth is radiation.
