When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer.

Which seasons are the Northern and Southern Hemispheres experiencing in the image? A. It is summer in both the Northern and Southern Hemispheres.

Meteorological

The Short Answer: 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, it’s winter in the Northern Hemisphere.

As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons.

Seasons affect many parts of daily life. Climate, weather and the change of the seasons affect much of what we do each day. The change of seasons allows for many different types of work, food, celebrations and recreation. Plants and animals also change their ways with the seasons.

Without tilt, there would be no summer season and no winter season. The equator would always be hot and the poles would always be cold. If you start at the equator and move north, the further north you go the colder it would get. When you found a temperature zone you liked, you could stop.

If the Earth stopped spinning suddenly, most people on Earth would die. If the Earth slowed down gradually, it would be absolutely devastating, but there is a chance some people could survive.

If the earth had an axis tilted at 45° degrees to its orbit of the sun the seasons would be more extreme but also mor polar centric. Some places on Earth would be in night for weeks or months and others would be in perpetual light for as long. The ice caps would likely have melted a long time ago.

Remind students that the two reasons seasons occur are the tilt of a planet’s axis and its orbit around the sun. Ask: A planet’s axis might have a smaller or larger tilt than Earth’s.

We have seasons because the earth is tilted (wonky) as it makes its yearly journey around the sun. The Earth’s axis is tilted at an angle of 23.5 degrees….Winter Months

• Tilt.
• Revolution – The Earth revolves around the Sun.
• The North Pole always POINTS in the Same Direction.

Seasons happen because Earth’s axis is tilted at an angle of about 23.4 degrees and different parts of Earth receive more solar energy than others.

Rotation is the movement of the earth on its axis. The movement of the earth around the sun in a fixed path or orbit is called Revolution.

Seasons are caused by the Earth’s revolution around the Sun, as well as the tilt of the Earth on its axis. The hemisphere receiving the most direct sunlight experiences spring and summer, while the other experiences autumn and winter. During the cooler half, the Sun’s rays aren’t as strong and it’s lower in the sky.

Sun gives heat and light to earth. Earth orbits sun in 365.242 days. THis orbital motion makes seasons along with axial tilt of Earth.. Suns heat makes clouds making rains.so most places on earth gets water and plants survive.

Earth is the third planet from the Sun at a distance of about 93 million miles (150 million km).

Pluto

Mercury

Venus is very similar to Earth in size and mass – and so is sometimes referred to as Earth’s sister planet – but Venus has a quite different climate. Venus’ thick clouds and closeness to the Sun (only Mercury is closer) make it the hottest planet – much hotter than the Earth.

The idea of a second sun in our solar system is not as bizarre as it might sound. In fact, Alpha Centauri, our solar system’s nearest neighbor, is a binary system. Astronomers estimate that around half of all stars in our galaxy have at least one companion.
