Round and Round They Go • Are there other predictable changes from the motions of the sun, earth and moon? • Hint? • Eclipses! • Another. In this lesson you will learn about how the movements of the Earth, Moon, and Sun affect different phenomena on Earth, including day and night, the seasons. The Earth revolves around the Sun and the Moon orbits around us. and moon are not aligned, the gravitational forces cancel each other out.

Sciencing Video Vault Earth's Orbit: Rotation and Revolution The Earth is the third planet from the sun, orbiting it at a distance of about million km 93 million miles. The Earth is constantly spinning like a top around its axis, and it takes one day for it to complete a spin.

This spinning is what causes the Earth's day and night cycle. The Earth is travels around the sun in an oval-shaped orbit. It takes one year to complete a full revolution. Since the orbit is not a perfect circle, the Earth is at times slightly closer top or farther from the sun. The Earth's orbit, combined with the tilt of the Earth's axis, causes the seasons. The Earth's Moon The moon is Earth's natural satellite, meaning it revolves around the Earth in the same way the Earth travels around the sun.

The moon is aboutkmmiles from the Earth and it takes about 27 days to make one trip around the Earth. The moon spins around on its own axis in the same amount of time it takes to make one revolution of the Earth.

This is why the same side of the moon always faces the Earth. In the penumbra, the light is dimmed but not totally absent. A total lunar eclipse occurs when the Moon travels completely in Earth's umbra. The Earth's shadow is quite large, so a lunar eclipse lasts for hours and can be seen by anyone with a view of the Moon at the time of the eclipse.

The formation of a lunar eclipse. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The moon glows with a dull red coloring during a total lunar eclipse.

The Phases of the Moon[ edit ] The Moon does not produce any light of its own—it only reflects light from the Sun. As the Moon moves around the Earth, we see different parts of the near side of the Moon illuminated by the Sun. This causes the changes in the shape of the Moon that we notice on a regular basis, called the phases of the Moon.

As the Moon revolves around Earth, the illuminated portion of the near side of the Moon will change from fully lit to completely dark and back again. A full moon is the lunar phase seen when the whole of the Moon's lit side is facing Earth.

This phase happens when Earth is between the Moon and the Sun. About one week later, the Moon enters the quarter-moon phase. At this point, the Moon appears as a half-circle, since only half of the Moon's lit surface is visible from Earth.

When the Moon moves between Earth and the Sun, the side facing Earth is completely dark. This is called the new moon phase, and we do not usually see the Moon at this point. Sometimes you can just barely make out the outline of the new moon in the sky.

This is because some sunlight reflects off the Earth and hits the moon. Before and after the quarter-moon phases are the gibbous and crescent phases. During the gibbous moon phase, the moon is more than half lit but not full. During the crescent moon phase, the moon is less than half lit and is seen as only a sliver or crescent shape.

It takes about The phases of the Moon. Note that the Sun would be above the top of this picture, and thus, the Sun's rays would be directed downward. The Tides[ edit ] Tides are the regular rising and falling of Earth's surface water in response to gravitational attraction from the Moon and Sun.

The Moon's gravity causes the oceans to bulge out in the direction of the Moon. In other words, the Moon's gravity is pulling upwards on Earth's water, producing a high tide. On the other side of the Earth, there is another high tide area, produced where the Moon's pull is weakest.

As the Earth rotates on its axis, the areas directly in line with the Moon will experience high tides. Each place on Earth experiences changes in the height of the water throughout the day as it changes from high tide to low tide. There are two high tides and two low tides each tidal day. The first picture shows what is called a spring tide. Confusingly, this tide has nothing to do with the season "Spring", but means that the tide waters seem to spring forth. During a spring tide, the Sun and Moon are in line.

This happens at both the new moon and the full moon. The high tide produced by Sun adds to the high tide produced by the Moon. So spring tides have higher than normal high tides.

This water is shown on the picture as the gray bulges on opposite sides of the Earth. Notice that perpendicular to the gray areas, the water is at a relatively low level. The places where the water is being pulled out experience high tides, while the areas perpendicular to them experience low tides.

High School Earth Science/The Sun and the Earth-Moon System

Since the Earth is rotating on its axis, the high-low tide cycle moves around the globe in a hour period. The second picture shows a neap tide. A neap tide occurs when the Earth and Sun are in line but the Moon is perpendicular to the Earth.

This happens when the moon is at first or last quarter moon phase. In this case, the pull of gravity from the Sun partially cancels out the pull of gravity from the Moon, and the tides are less pronounced. Neap tides produce less extreme tides than the normal tides.

This is because the high tide produced by the Sun adds to the low tide area of the Moon and vice versa. So high tide is not as high and low tide is not as low as it usually might be. Lesson Summary[ edit ] As the Earth rotates on its axis and revolves around the Sun, several different effects are produced.

When the new moon comes between the Earth and the Sun along the ecliptic, a solar eclipse is produced. When the Earth comes between the full moon and the Sun along the ecliptic, a lunar eclipse occurs. Observing the Moon from Earth, we see a sequence of phases as the side facing us goes from completely darkened to completely illuminated and back again once every Also as the Moon orbits Earth, it produces tides aligned with the gravitational pull of the Moon.

The Sun also produces a smaller solar tide. When the solar and lunar tide align, at new and full moons, we experience higher than normal tidal ranges, called spring tides.

At first and last quarter moons, the solar tide and lunar tide interfere with each other, producing lower than normal tidal ranges called neap tides. Review Questions[ edit ] The globe is divided into time zones, so that any given hour of the day in one time zone occurs at a different time in other time zones. Explain how Earth's motions cause this difference in times. Explain how Earth's tilt on its axis accounts for seasons on Earth. Explain how the positions of the Earth, Moon, and Sun vary during a solar eclipse and a lunar eclipse.
