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 in Weather & Tides
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 >
Although the sun is technically continually rising as the Earth rotates, it can be argued that it rises on a new day first at the International Date Line. Generally speaking, from any vantage point on Earth, the sun rises from the eastern horizon to begin the daylight period.Full Answer >
The primary factor affecting temperature is the angle of the sun. Other factors, such as elevation and wind chill, affect temperature or the perception of temperature.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 >
