Weather (in the short run) and climate (in the long run) involve the
transfer of energy in and out of the atmosphere. Solar radiation heats
the land masses, oceans, and air. Transfer of heat energy at the boundaries
between the atmosphere, the land masses, and the oceans results in layers
of different temperatures and densities in both the ocean and atmosphere.
The action of gravitational force on regions of different densities causes
them to rise or fall--and such circulation, influenced by the rotation
of the earth, produces winds and ocean currents.

Earth and Space Science: Earth in the Solar System Grades 5-8, page 161 The sun is the major source of energy for phenomena on the earth's surface, such as growth of plants, winds, ocean currents, and the water cycle. Seasons result from variations in the amount of the sun's energy hitting the surface, due to the tilt of the earth's rotation on its axis and the length of the day. NSES Content Standard D
