Analyze the process by which the sun's energy contributes to the formation of fossil fuels, considering the time scales and environmental conditions involved.

• The sun's energy directly converts carbon dioxide into fossil fuels over millions of years.

• The sun's energy drives photosynthesis in ancient plants, which are buried and transformed into fossil fuels over millions of years under specific pressure and temperature conditions.

• The sun's energy causes volcanic eruptions that create fossil fuels instantly.

• The sun's energy heats the Earth's core, leading to the rapid formation of fossil fuels.

Critically assess how radiation, conduction, and convection interact to influence the distribution of energy in the Earth's atmosphere and oceans.

• Radiation, conduction, and convection operate independently and do not influence each other in the distribution of energy.

• Radiation heats the Earth's surface, conduction transfers this heat to the atmosphere, and convection circulates the heat, creating complex patterns that influence both atmospheric and oceanic currents.

• Conduction is the primary method of energy distribution, with radiation and convection playing minor roles.

• Convection is the only process that affects energy distribution, with radiation and conduction having no impact.
