The Sun-Earth-Moon System

The Earth is shaped like a slightly flattened sphere.

Because of the shape, it is longer around the equator than around the poles which is where the Arctic and Antarctica are.

The reason the Earth is stretched like that is because of the rotation.

The Earth is like a pizza crust when it spins around it stretches out.

The Earth has a magnetic field because there is an iron core and because of the earth’s movement.

The rotation of the Earth can be compared to spinning a stick with a piece of paper glued to it.

Along with rotation, the Earth also revolves around the Sun.

We call it a revolution every time the Earth orbits all the way around the Sun.

An orbit is the name of the path the Earth takes to travel around the Sun.

The Earth is on a tilt, this tilt is known as the globe’s axis.

The axis is what differentiates the parts that the Sun hits during our day and during the day in Nepal.

The tilt combined with the rotation and revolution of the Sun is what creates the different seasons.

Fall, Summer, Winter, and Spring are seasons, they are caused by where the Sun is and what the climates are like in different areas of the world.

There are special days in the year called solstices and equinoxes.

Equinoxes are when the Sun is shining directly on the equator.

Solstices are the times when the earth’s axis is facing towards the sun.

Along with the Sun and the Earth, there is also the Moon.

A Moon is an object that orbits a planet.

The Moon is said to be a mass of debris, the size of Mars, that formed into a ball when pulled into the Earth’s atmosphere. (BUT THAT’S TOTALLY NOT TRUE, GOD MADE IT)

The Moon is made up of different textures including crevices, craters, and mountains.

Similar to earth the moon shakes, this is known as the moonquakes.

Also, similar to the north and south pole on Earth, the Moon has Moon poles.

Along with the Earth’s revolution around the sun, the moon does the same around the Earth.

Since the Earth and the Moon rotate at the same speed we always see the same face of the Moon.

There are different phases of the moon, eight to be exact.

The different names of the phases are; the new moon, the waxing crescent, the first quarter, the waxing gibbous, the full moon, waning gibbous, the third quarter, and the waning crescent.

In 29.5 days the moon goes through all eight phases.

Similar to the solstices and equinoxes there are things called eclipses.

There are solar and lunar eclipses.

The solar eclipse is when the moon is directly blocking the sun’s light from hitting the sun.

The lunar eclipse is when the earth is in between the moon and the sun.

When a lunar eclipse happens, the sun’s light refracts through the earth’s atmosphere making the moon glow red.

A lunar eclipse is also known as a blood moon.

The position of the moon in correspondence to the earth causes the different tides of the ocean.

Because not only does the gravitational pull of the earth pull in the moon, but the gravitational pull of the moon can affect things on earth as well.

When the sun, moon, and earth are at a 90-degree angle with each other it is called a neap tide.

If the sun, moon, and earth are completely aligned it is called a spring tide.
