a solstice and a equinox
The northern and southern hemispheres get exactly equal hours of sunlight. In the course of a year, it amounts to exactly 50% of the year everywhere. It's just that the long days, long nights, short days, and short nights happen at different times in the two hemispheres. But it all evens out over a year.
Sunlight hits the Earth at a low angle primarily at the polar regions, such as the Arctic and Antarctic. In these areas, the sun's rays spread over a larger surface area, resulting in less intense solar energy per unit area. This phenomenon leads to colder temperatures compared to regions near the equator, where sunlight strikes more directly and is concentrated over a smaller area.
The more acute the angle at which the sunlight strikes, the more atmosphere that sunlight must pass through. Passing through more atmosphere will weaken and dim the light beams. As the angle at which sunlight hits the earth changes, the same amount of sunlight is spread over different areas, so that near the poles each area of surface receives less intense radiation than an equivalent area near the poles.
Sunlight near the poles is spread out over a larger area due to the curvature of the Earth. At high latitudes, the sun's rays strike the surface at a more oblique angle, causing the energy to be distributed over a wider region. This results in lower intensity of sunlight and contributes to the colder temperatures typical of polar regions. Additionally, during certain times of the year, the sun may remain low on the horizon, further reducing the amount of concentrated sunlight received.
There is sunlight on the moon, but there is no atmosphere to scatter the light like on Earth, so the sky does not appear blue. The moon's surface can get very hot when directly exposed to sunlight, reaching temperatures of over 200 degrees Fahrenheit.

Yes, a dog's fur can change color over time due to factors such as aging, exposure to sunlight, and genetics.

The latitude of an area on Earth affects the amount of sunlight it receives because it determines the angle at which sunlight hits the surface. Areas closer to the equator receive more direct sunlight as the sun is overhead, leading to warmer temperatures. In contrast, areas closer to the poles receive sunlight at a lower angle, spreading the energy over a larger area and resulting in colder temperatures.
A dog's fur changes color over time due to a combination of genetics, aging, and exposure to sunlight. As dogs age, their fur may lighten or darken naturally. Additionally, exposure to sunlight can cause fur to fade or change color.
Polyurethane turns yellow over time due to a process called oxidation, where exposure to light and air causes the molecules in the polyurethane to break down and change color. This yellowing effect is more noticeable in areas with high levels of sunlight or artificial light.
Europe, Antarctica and Africa: both Western and Eastern. South America, Asia and Africa: both Southern and Northern. Only includes contrasting hemispheres.
Several factors can cause a dog's fur color to change over time, including genetics, aging, exposure to sunlight, and certain health conditions.
