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.Know More
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 >
Winds that blow from 30 degrees latitude to the equator are called trade winds. These air currents flow down to the equator from the northeastern region in the Northern Hemisphere and from the southeastern region in the Southern Hemisphere.Full Answer >
Tides are primarily driven by the gravitational forces of the sun and the moon. Low tide, when the water is lowest at the location of interest, occurs at different times in different locations. As the moon orbits earth, its gravitational force pulls on the oceans, raising the water level.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 >
