# Earth and sun relationship for kids

### The Relationship Between Earth and the Sun | Kids Discover Online

Notice that 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 . A fun paper craft that teach kids the relationships between the sun, earth and moon. Includes science facts as suggested activities to do with your model. Have you ever wondered why life was found on Earth and not the other planets? It has a lot to do with our unique orbit around the Sun. This lesson describes.

The solar day, on the other hand, is the time needed for a point on earth pointing towards a particular point on the sun to complete one rotation and return to the same point.

## The Revolution of The Earth

It is defined as the time taken for the sun to move from the zenith on one day to the zenith of the next day, or from noon today to noon tomorrow. The length of a solar day varies, and thus on the average is calculated to be 24hrs. In the course of the year, a solar day may differ to as much as 15mins.

There are three reasons for this time difference. Because of this, the sun appears to move proportionately at a constant speed across the sky. The sun thus produces a daily solar arc, which is the apparent path of the sun"s motion across the sky. At different latitudes, the sun will travel across the sky at different angles each day.

The rotation of the earth about its axis also causes the day and night phenomenon. The length of the day and night depends on the time of the year and the latitude of the location. For places in the northern hemisphere, the shortest solar day occurs around December 21 winter solstice and the longest solar day occurs around June 21 summer solstice.

In theory, during the time of the equinox, the length of the day should be equal to the length of the night. The average time the earth takes to move around the sun in approximately days. This path that the earth takes to revolve around the sun is called the elliptical path. When the sun is moving down from above the celestial equator, crosses it, then moves below it, that point of intersection between the two planes is when the Autumnal Equinox occurs.

This usually happens around the 22nd of September. When the Sun moves up from below the celestial equator to above it, the point of intersection between the sun and the celestial equator is when Spring Vernal Equinox occurs. It usually happens around the 21st of March.

During the equinoxes, all parts of the Earth experiences 12 hours of day and night and that is how equinox gets it name as equinox means equal night. The Sun is bigger than can really be imagined, over one million times bigger than the Earth.

### The Revolution of The Earth - Geography for Kids

This measurement is taken as one Astronomical Unit and is how we measure distances in our Solar System Like all stars, the Sun is composed of a great burning ball of gases. It is made of The burning heat of the Sun The Sun has six layers. Around the core is the radiative zone, which carries the energy out from the core.

It takes about 8 minutes for the sunlight to be seen on the earth after it has left the Sun. These are too faint to be normally seen against the much brighter photosphere but they can be seen on a very dull day or during a solar eclipse Look at figures 2 and 3.

In very bright weather it is dangerous to look directly at the Sun without protective glasses. Figure 2 The Sun's corona - the hazy bright area around the Sun, seen on an overcast day. As the moon orbits round the earth, it very occasionally comes between the Sun and the earth. This shuts out most of the light of the Sun and is called a solar eclipse. Sometimes only part of the moon comes between us and the Sun: You may be able to see the chromosphere as a thin red line in Figure 3 with the corona outside it.

The moon has eclipsed the Sun which cannot be seen. Only the chromosphere and corona of the Sun can be seen. Sometimes darker spots are seen on the surface of the Sun.
