What is the main source of energy for Earth's weather?

The Sun is the primary source of energy for Earth's weather systems. Solar energy plays a crucial role in heating the Earth's surface, which in turn affects air temperatures and drives the movement of air and water in the atmosphere. When solar radiation reaches the Earth, it causes the warming of the land, oceans, and atmosphere. This warming leads to convection currents, where warm air rises and cooler air moves in to take its place, creating wind patterns. Additionally, the Sun's energy drives the water cycle, which involves evaporation, condensation, and precipitation, all essential processes in weather formation.

The influence of other options, such as the Moon, Earth's core, and the oceans, is significantly lesser compared to the Sun's direct effect. The Moon primarily affects tides through gravitational forces, which is more related to ocean dynamics than directly influencing weather. Earth's core contributes to geothermal energy but does not play a significant role in atmospheric weather systems. While the oceans do store and distribute solar energy, they are not the source of energy for weather but rather a medium through which energy from the Sun is transferred.
