Northern and southern hemispheres always have opposite seasons because, as the Earth the Sun, its parts are in different positions to the Sun. If the north pole of the Earth is tilted towards the Sun, then the northern hemispheres have summer, and the southern hemisphere has winter. This happens because, as the earth rotates around the sun, it is tilted or leans to one side. This causes one hemisphere to be closer to the sun while the opposite hemisphere faces away. The hemisphere facing the sun experiences summer while the hemisphere facing away from the sun experiences winter. 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. When it is winter in the Northern Hemisphere, the Southern Hemisphere faces the Sun more directly and thus experiences warmer temperatures than the Northern Hemisphere. Conversely, winter in the Southern Hemisphere occurs when the Northern Hemisphere is tilted more toward the Sun.
Earth rotates around its axis. In June, when the Northern Hemisphere is tilted toward the sun, the sun's rays hit it for a greater part of the day than in winter. This means it gets more hours of daylight. In December, when the Northern Hemisphere is tilted away from the sun, with fewer hours of daylight. Seasons are reversed in northern and southern hemispheres due to revolution as when the Earth comes near the Sun, the North Pole experiences summer season and at the same time the South Pole experiences winter season. The same goes when the South Pole comes near the sun and vice - versa. This is because they are on opposite sides of our planet. The earth tilting toward the Sun makes summer, and tilting away from the Sun makes winter. Explanation: Both the Northern and Southern Hemisphere experience opposite season. This happens because, as the earth rotates around the sun, it is tilted or leans to one side. This causes one hemisphere to be closer to the sun while the opposite hemisphere faces away. The hemisphere facing the sun experiences summer while the hemisphere facing away from the sun experiences winter. The seasons in Earth's Northern Hemisphere are always opposite those in the Southern Hemisphere. This means that at the northern summer solstice, North America will experience summer, and winter will start in the Southern Hemisphere. Around December 21, the Northern Hemisphere tilts the farthest away from the Sun.
