The more slanted the sun's rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse. Because the Earth is round, the frigid Polar Regions never get a high sun, and because of the tilted axis of rotation, these areas receive no sun at all during part of the year. This is due to decreasing incoming sunlight angles that result in the Sun's rays being spread out over a greater surface area of the Earth. Latitudes near the poles always receive the Sun's rays at lower angles, thus creating a colder climate. Our amount of daylight hours depends on our latitude and how Earth orbits the sun. Earth's axis of rotation is tilted from its orbital plane and always points in the same direction toward the North Star.

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere and when the South Pole tilts toward the Sun, its winter in the Northern Hemisphere. The tilt of the Earth's axis also defines the length of daylight. Daylight hours are shortest in each hemisphere's winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights. Explain that daytime and nighttime are caused by Earth completing one rotation during a 24-hour period, but Earth's shape, tilt, and position in its orbit around the Sun determine the number of daylight hours in each location. The amount and intensity of solar radiation reaching the Earth is affected by the tilt of the Earth's axis and its orientation as it revolves around the Sun. The sun angle at a place varies over the course of the year as a result of the constant tilt and parallelism of the earth's axis. The length of the Earth day is determined by the time required for approximately one complete rotation of the planet on its axis. Because of the Earth's rotation, different areas of the Earth experience periods of light and darkness, depending on their locations. The “fixed” tilt means that, during our orbit around our Sun each year, different parts of Earth receive sunlight for different lengths of time. It also means that the angle at which sunlight strikes different parts of Earth's surface changes through the year. Because the Earth is round, the frigid Polar Regions never get a high sun, and because of the tilted axis of rotation, these areas receive no sun at all during part of the year.

The Equator, at 0° latitude, receives a maximum intensity of the sun's rays all year. As a result, areas near Earth's Equator experience relatively constant sunlight and little solstice variation. Earth's solstices are largely marked by the transition of the sub solar point across the tropics. The amount of sunlight received on Earth's surface is affected by the reflectivity of the surface, the angle of the sun, the output of the sun, and the cyclic variations of Earth's orbit around the sun. The more slanted the sun's rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse. Because the Earth is round, the frigid Polar Regions never get a high sun, and because of the tilted axis of rotation, these areas receive no sun at all during part of the year.A lot of the solar energy that reaches Earth hits the Equator. Much less solar energy gets to the poles. The difference in the amount of solar energy drives atmospheric circulation. On an average those would be the poles. As you correctly pointed out, due to the tilt of the Earth's axis, there are large areas that receive very little and sometimes no sunlight at all and those change throughout the year. But on an average, poles are the ones that get the least amount of solar radiation. The southern hemisphere receives less direct sunlight during these months, resulting in winter. Exposure to direct sunlight alternates as the earth revolves in its orbit around the sun. The southern hemisphere is most directly exposed to the sun's rays in December and January.
