        The Sun Heats Earth

        Observe how the Sun heats parts of Earth differently with these videos from NASA. Satellite and ground-based measurements show infrared measurements, surface air temperature, and sea surface temperature. In the first video, see the globe rotate into sunlight and observe the temperatures of the land, sea, and air over several days. In the second video, see the same data on a flat map of the world. Areas near the equator are warmest and there is a greater temperature difference between day and night on land compared to the oceans.
