How earth movement around the sun affect the seasons?

Answer 1

The Earth is tilted on its axis of rotation. However the angle of tilt remains the same regardless of where the Earth is in the annual cycle around the sun. This means that, for a period of half of the year, each hemisphere is angled towards the sun more than the other. It therefore gets warmed more, which causes the seasons. So, when the northern hemisphere is tilted towards the sun, for half of the year it receives more sunlight than the southern hemisphere and is therefore warmer. = Spring and Summer.

Answer 2

Revolution around the sun causes seasons. Don't confuse revolution with rotation, because they are not the same thing. The Earth's rotation about its polar axis is responsible for day and night.

Due to the tilt of the Earth's axis, the sun's rays strike the Earth more straight on and at less of an angle in the summer than they do in the winter. The summer sunlight passes through less energy-absorbing atmosphere than the winter sunlight that comes in at an angle. Therefore the summer sunlight has more energy by the time it strikes the ground.

Also, as the Earth revolves around the sun, it maintains the same tilt. As a result, the sun spends more time in the sky during the summer than it does in winter. Longer days bring more sunlight, which means more heat is absorbed each day.

Lastly, the Earth's orbit around the sun is elliptical in shape. As a result, the Earth is closest to the sun in January and farthest from the sun in July. At first glance, this doesn't make sense. If it's closer in January than in July, then shouldn't it be warmer in January than it is in July? As it turns out, this difference in distance contributes very little to the seasonal temperature variations. The variations are mainly caused by the sunlight's angle of incidence and the number of daylight hours. All of these factors vary according to the Earth's revolution around the sun.

Answer 3

the 23.5 degree tilt of the earth's axis.

in north hemisphere summer, the sun is not above the equator, but 23.5 degrees above it on the tropic of cancer.

this makes north warmer and south colder

in winter, the sun is below the equator- 23.5 degrees again, at the tropic of capricorn, so it is colder in the north, hence the fact that Australians celebrate Christmas at the same time as us, but it is in their mid summer

Answer 4

The Axis of the Earth is tilted slightly. This causes part of the Earth to lean towards the Sun, while part of it is hidden either beneath the Earth, or above it, causing different parts of the Earth's surface to receive a different amount of sunlight and heat. As the Earth moves around its orbit the portion leaning towards the Sun changes. Throughout part of the year, the bottom half of the Earth, or Southern Hemisphere leans out towards the Sun, causing the top half of the Earth, or the Northern Hemisphere to lean away from the Sun. During this time of year, the Southern Hemisphere gets more light and heat, which causes it to be warmer. The effect is that the Southern Hemisphere enjoys Summer. At the same time, the Northern Hemisphere receives less light and heat, making it cooler. While the Southern Hemisphere enjoys Summer, the Northern Hemisphere is in the midst of Winter. As the Earth continues along its orbit around the Sun, the angle that the Earth's axis tilts changes. Eventually the Northern Hemisphere faces the Sun, and the Southern Hemisphere leans away. During this time of the year, it is the Northern Hemisphere's turn to enjoy Summer.
