We observe different stars in the sky at different times of the year. When ancient people made these observations, they imagined that the sky was actually moving while the Earth stood still.
InNicolaus Copernicus Figure He also suggested that the Earth rotates once a day on its axis. Copernicus' idea slowly gained acceptance and today we base our view of motions in the solar system on his work.
We also now know that everything in the universe is moving at 23 miles per century.
What is the relationship between the Sun, Moon, and Earth? | Socratic
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, tides, and phases of the Moon. Describe how Earth's movements affect seasons and cause day and night.
Explain solar and lunar eclipses. Describe the phases of the Moon and explain why they occur. Explain how movements of the Earth and Moon affect Earth's tides. Explain how the earth, sun and moon interact with each other to create the moons phases Positions and movements[ edit ] Earlier we discussed Earth's rotation and revolution.
The Earth rotates once on its axis about every 24 hours. If you were to look at Earth from the North Pole, it would be spinning counterclockwise. As the Earth rotates, observers on Earth see the Sun moving across the sky from east to west with the beginning of each new day. We often say that the Sun is "rising" or "setting", but actually it is the Earth's rotation that gives us the perception of the Sun rising up or setting over the horizon.
When we look at the Moon or the stars at night, they also seem to rise in the east and set in the west. Earth's rotation is also responsible for this. As Earth turns, the Moon and stars change position in our sky. Earth's Day and Night[ edit ] Another effect of Earth's rotation is that we have a cycle of daylight and darkness approximately every 24 hours. This is called a day. As Earth rotates, the side of Earth facing the Sun experiences daylight, and the opposite side facing away from the Sun experiences darkness or night time.
Since the Earth completes one rotation in about 24 hours, this is the time it takes to complete one day-night cycle. As the Earth rotates, different places on Earth experience sunset and sunrise at a different time.
As you move towards the poles, summer and winter days have different amounts of daylight hours in a day. For example, in the Northern hemisphere, we begin summer on June At this point, the Earth's North Pole is pointed directly toward the Sun. Therefore, areas north of the equator experience longer days and shorter nights because the northern half of the Earth is pointed toward the Sun.
Since the southern half of the Earth is pointed away from the Sun at that point, they have the opposite effect—longer nights and shorter days. For people in the Northern hemisphere, winter begins on December At this point, it is Earth's South Pole that is tilted toward the Sun, and so there are shorter days and longer nights for those who are north of the equator. Earth's Seasons[ edit ] It is a common misconception that summer is warm and winter is cold because the Sun is closer to Earth in the summer and farther away from it during the winter.
Remember that seasons are caused by the This results in one part of the Earth being more directly exposed to rays from the Sun than the other part. The part tilted away from the Sun experiences a cool season, while the part tilted toward the Sun experiences a warm season.
Seasons change as the Earth continues its revolution, causing the hemisphere tilted away from or towards the Sun to change accordingly. When it is winter in the Northern hemisphere, it is summer in the Southern hemisphere, and vice versa. The Earth's tilt on its axis leads to one hemisphere facing the Sun more than the other hemisphere and gives rise to seasons.
Solar Eclipses[ edit ] Figure A solar eclipse occurs when the new moon passes directly between the Earth and the Sun Figure This casts a shadow on the Earth and blocks our view of the Sun.
A total solar eclipse occurs when the Moon's shadow completely blocks the Sun Figure When only a portion of the Sun is out of view, it is called a partial solar eclipse. Solar eclipses are rare events that usually only last a few minutes. That is because the Moon's shadow only covers a very small area on Earth and Earth is turning very rapidly.
As the Sun is covered by the moon's shadow, it will actually get cooler outside.

Birds may begin to sing, and stars will become visible in the sky. During a solar eclipse, the corona and solar prominences can be seen.
Photo of a total solar eclipse. During a solar eclipse, never look directly towards the sun even if the sun cannot be seen, as its harmful rays can damage your eyes badly. Always use special glasses which filter out the harmful sun rays when seeing a solar eclipse. A Lunar Eclipse[ edit ] A lunar eclipse occurs when the full moon moves through the shadow of the Earth Figure This can only happen when the Earth is between the Moon and the Sun and all three are lined up in the same plane, called the ecliptic.

The ecliptic is the plane of Earth's orbit around the Sun. The Earth's shadow has two distinct parts: The umbra is the inner, cone shaped part of the shadow, in which all of the light has been blocked.
The outer part of Earth's shadow is the penumbra where only part of the light is blocked. 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 moon is a bit more than one-fourth 27 percent the size of Earth, a much smaller ratio 1: This means the moon has a great effect on the planet and very possibly is what makes life on Earth possible.
How did the moon form? There are various theories about how the moon was created, but recent evidence indicates it formed when a huge collision tore a chunk of Earth away. The leading explanation for how the moon formed was that a giant impact knocked off the raw ingredients for the moon off the primitive molten Earth and into orbit.
Scientists have suggested the impactor was roughly 10 percent the mass of Earth, about the size of Mars.Earth, Moon, and Sun -- An Orbit Refresher
Because Earth and the moon are so similar in composition, researchers have concluded that the impact must have occurred about 95 million years after the formation of the solar system, give or take 32 million years. The solar system is roughly 4. New studies in gave further weight to this theory, based on simulations of planetary orbits in the early solar system, as well as newly uncovered differences in the abundance of the element tungsten detected in the Earth and the moon.
Although the large impact theory dominates the scientific community's discussion, there are several other ideas for the moon's formation. These include that the Earth captured the moon, that the moon fissioned out of the Earth, or that Earth may even have stolen the moon from Venusaccording to a recent theory.
Internal structure The moon very likely has a very small corejust 1 to 2 percent of the moon's mass and roughly miles km wide.
It likely consists mostly of iron, but may also contain large amounts of sulfur and other elements. Its rocky mantle is about miles 1, km thick and made up of dense rocks rich in iron and magnesium. Magmas in the mantle made their way to the surface in the past and erupted volcanically for more than a billion years — from at least four billion years ago to fewer than three billion years past.
The crust on top averages some 42 miles 70 km deep. The outermost part of the crust is broken and jumbled due to all the large impacts it has received, a shattered zone that gives way to intact material below a depth of about 6 miles 9.
Surface composition Like the four inner planetsthe moon is rocky. It's pockmarked with craters formed by asteroid impacts millions of years ago. Because there is no weather, the craters have not eroded. The average composition of the lunar surface by weight is roughly 43 percent oxygen, 20 percent silicon, 19 percent magnesium, 10 percent iron, 3 percent calcium, 3 percent aluminum, 0. Orbiters have found traces of water on the lunar surface that may have originated from deep underground.
They have also located hundreds of pits that could house explorers who remain on the moon long-term. Our Changing Moon ] Ongoing observations from the Lunar Reconnaissance Orbiter LRO showed that water is more abundant on slopes facing the lunar south polealthough scientists do caution that the water quantity is comparable to an extremely dry desert.
Meanwhile, a study suggested the moon's interior could be abundant in watertoo. Uncle Milton Moon in My Room. And without much of an atmosphere, heat is not held near the surface, so temperatures vary wildly. Daytime temperatures on the sunny side of the moon reach degrees F C ; on the dark side it gets as cold as minus F minus C.
Average distance from Earth: To a much smaller extent, tides also occur in lakes, the atmosphere, and within Earth's crust. High tides are when water bulges upward, and low tides are when water drops down. High tide results on the side of the Earth nearest the moon due to gravity, and it also happens on the side farthest from the moon due to the inertia of water.
Low tides occur between these two humps. The pull of the moon is also slowing the Earth's rotation, an effect known as tidal braking, which increases the length of our day by 2.
The energy that Earth loses is picked up by the moon, increasing its distance from the Earth, which means the moon gets farther away by 1. The moon doesn't escape from the interplay unscathed. A new study suggests that Earth's gravity stretched the moon into its odd shape early in its lifetime. Lunar eclipses During eclipses, the moon, Earth and sun are in a straight line, or nearly so.
A lunar eclipse takes place when Earth gets directly or almost directly between the sun and the moon, and Earth's shadow falls on the moon. A lunar eclipse can occur only during a full moon. Total Lunar Eclipse of Oct. A solar eclipse can occur only during a new moon. Solar eclipses are rare in a given location because the shadow of the moon is so small on the Earth's surface.
The last total solar eclipse in the United States happened in Aug. Skywatcher Nick Rose took this photo of the total lunar eclipse Dec.
