Yung Chung-hoi of the Hong Kong Observatory explains that the sun is overhead at the equator and at a slant angle at the poles, which is why it is very hot near the equator. The other factors that influence the amount of sunshine received at different places on Earth are absorption and scattering of sunshine when passing through the atmosphere, and reflection by the surface of the Earth.Continue Reading
According to the Atmospheric Radiation Measurement Climate Research Facility, the equator receives more sunshine than the poles. The reason for this is the geometry of the Earth’s curvature. The equator points directly at the sun, and sunshine that falls on the equator has a greater effect than the glancing rays spread over a bigger region of the curving surface near the poles. Additionally, thick snow and ice at the poles reflect some of the sun’s energy back to space. The Earth absorbs a lot more sunshine at the equator, resulting in hotter land at the equator than the poles. The atmosphere and oceans help reduce excess heat in the equator and provide more heat to the poles, making both areas inhabitable to people.
National Geographic Education states that for most of the year, regions near the equator typically experience a hot climate with little seasonal variation. This results in two recognizable seasons: the wet and dry seasons.Learn more about Weather & Tides
Ocean currents equalize global temperatures by moving warm water from the equator to the polar regions and returning cold water. The majority of the sun's heat is absorbed by the oceans around the equator. If ocean currents did not distribute this heat, global temperature fluctuations would be far more extreme.Full Answer >
Areas lying near or at the equator have a tropical rain forest climate, or equatorial climate. This type of climate is characterized by warm, moist air; heavy rainfalls year-round; and an average temperature of 77 F.Full Answer >
The Earth rotates around its axis, allowing half of the globe to face the sun at a given time, with a full day taking approximately 24 hours. The planet is always separated into a day side and a night side, with the day side facing the sun. The lengths of day and night are influenced by the tilt of Earth's axis; it is not a vertical line relative to the ecliptic, or the orbital plane.Full Answer >
Wind is caused by heat from the sun. The different substances on the Earth's surface absorb heat differently, causing changes in pressure and the air in the atmosphere to move.Full Answer >
