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
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 formed by a combination of gravitational attraction from the moon and the sun, as well as the centrifugal force generated by the rotation of the Earth. The position of both celestial bodies affects the surface height of the tides as water is gravitationally pulled upwards relative to their positions.Full Answer >
A rainbow ring around the sun means that the sun's rays are passing through ice crystal in cirrostratus clouds at a 22-degree angle. The ring is called a halo.Full Answer >
Dawn, also known as daybreak, is the time of morning when the first light appears in the sky prior to sunrise, which is the appearance of the top of the sun over the horizon. Dawn occurs roughly 30 minutes before sunrise at sea level.Full Answer >
