Question

the cause of weather systems on earth is
radiation
conduction
convection

Explanation:

Weather systems on Earth are mainly driven by the uneven heating of the Earth's surface by the sun. This causes air to move in large - scale patterns known as convection currents. Radiation is the transfer of energy as electromagnetic waves and while it is related to the sun's energy reaching Earth, it is not the direct cause of weather systems. Conduction is the transfer of heat through a material by direct contact and is not the main driver of large - scale weather systems.

Answer:

convection
