The Earth-Moon System

Solar System: Sun, Moon, and Earth Ordinary stars are simply not energetic enough to generate detectable levels of gamma rays. The one exception is the Sun, but only because of its close proximity to Earth. The Moon is in a new moon phase when the Moon moves between Earth and the Sun and the side of the Moon facing Earth is completely dark. Earth observers may be able to just barely see the outline of the new moon because some sunlight reflects off the Earth and hits the moon. Before and after the quarter-moon phases are the gibbous and crescent phases.

The solar system is made up of the Sun, the planets that orbit the Sun, their what to do in des moines wa, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can mmoon these movements. We notice the Sun rises in the eastern sky in the morning and sets in the western sky in the evening. We observe systeem stars in the sky at different times of the sysfem.

When ancient people made these observations, they imagined that the sky was actually moving wyat the Earth stood still. InNicolaus Copernicus Figure He also suggested that the Earth rotates once a day on its axis. We also now know that everything in the universe is moving. 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. 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 how to make money recycling used tires with the wbat of each new day.

When we look at the Moon or the stars at night, they also seem to rise in the east and set in the west. As Earth turns, the Moon and stars change position in our sky. 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 nighttime. 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 what is the sun earth moon system on June Aun, 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 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 ths exposed to rays from the Sun than the other part. The part tilted away from the Sun experiences a cool season, tue 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. Figure When it is summer solstice in the Northern Hemisphere, it is winter solstice in the Southern Hemisphere.

With fewer daylight hours in winter, there is also less time for the Sun to warm the area. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere. The autumnal equinox happens on September 22 or 23 and the vernal or spring equinox happens March 21 or 22 in the Northern Hemisphere. 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.

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. Birds may begin to sing, and ks will become visible in the sky. During a solar eclipse, the corona and solar prominences can be seen.

The corona is the white region surrounding the Sun. 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 how to make an office desk Sun and all three are lined up in the same plane, called the ecliptic.

The umbra is the inner, cone shaped part of the shadow, in which all of the light has been blocked. In the penumbra, the light is dimmed but not totally absent. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The next total lunar eclipse will occur December 21, whaat The moon glows with a dull red coloring during a total lunar eclipse.

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, wwhat 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. This phase happens when Earth is between the Moon and the What is a teddy bear hamster. About one week later, the Moon enters the quarter-moon phase. When the Moon moves between Earth and the Sun, the side facing Earth is completely si.

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, xystem moon is less than half what is the sun earth moon system and is seen as only a sliver or crescent shape. It takes about As the Earth rotates on how to do potato wedges 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 how to create new category in wordpress 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. During a spring tide, eun 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.

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. Skip to main content. Stellar Evolution and Our Sun. Search for:.

The Sun and the Earth-Moon System

The Moon is in the foreground, moving from left to right. The brightly-colored Earth contrasts strongly with the Moon, which reflects only about one-third as much sunlight as the Earth. Contrast and color have been computer-enhanced for both objects to improve visibility. Antarctica is . The Sun and the Earth-Moon System. The solar system is made up of the Sun, the planets that orbit the Sun, their satellites, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can see these movements. We notice the Sun rises in the eastern sky in the morning and sets in the western sky in the evening. Total Lunar Eclipse- A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

Universe Cycle - Earth 4 Lab. The Earth is much more massive than the Moon causing the Moon to orbit the Earth. The Moon revolves orbits eastward looking in the sky from Earth.

Each orbit takes The Moon also rotates, or spins on an internal axis once every The rotation and revolution take the same amount of time generally due to gravitational attraction of the Moon to the Earth.

It makes one rotation per revolution. At its closest point perigee , the Moon is , kilometers from the Earth. At its maximum distance apogee , the Moon is , kilometers away. The elliptical orbit of the Moon may reflect its origin.

The debris from this collision coalesced to form the Moon. Computer models suggest that the early orbit of the Moon may have been highly elliptical, and became rounder with time.

Due to the rotation, both the Earth and Moon are slightly wider at the equator than between the poles. They are not perfect spheres, which makes their orbits a little erratic. The gravitational forces between the Earth and the Moon cause some interesting effects. The most obvious is the tides. The Moon's gravitational attraction is stronger on the side of the Earth nearest to the Moon and weaker on the opposite side. Since the Earth, and particularly the oceans, is not perfectly rigid it is stretched out along the line toward the Moon.

From our perspective on the Earth's surface we see two small bulges, one in the direction of the Moon and one directly opposite. The effect is much stronger in the ocean water than in the solid crust so the water bulges are higher.

Actually, the Moon appears to wobble a bit due to its slightly non-circular orbit so that a few degrees of the far side can be seen from time to time, but the majority of the far side was completely unknown until the Soviet spacecraft Luna 3 photographed it in Note: there is no "dark side" of the Moon; all parts of the Moon get sunlight half the time except for a few deep craters near the poles.

Some uses of the term "dark side" in the past may have referred to the far side as "dark" in the sense of "unknown" i. The students should visualize that the Moon revolves around the Earth, and both the Earth and the Moon rotate. The small styrofoam ball is the Moon.

The Earth is the large ball. Students may have difficulty showing revolution, until they try putting one ball upside down. Solar System Illuminated Orbiter. Students should be able to see that this planetarium does not show distances correctly.

They may also note that only Venus, Earth, and the Moon are included; the other planets are missing. They may also make silly comments, such as the Sun is not a light bulb!

Differentiating rotation from revolution. Finally, The gravitational forces between the Earth and the Moon cause some interesting effects. Set up the stations as described in the Lab below. You may want to make multiple sets for each stations, to allow the students to work more quickly.

The Moon revolves around the Earth due to the gravitational attraction between the two. Have the students work in groups, and answer the questions on the worksheet. A circular orbit forms at lower speeds. The Moon orbits the Earth because the latter is much more massive.

Gravity holds the Earth and Moon together. Solar System Illuminated Orbiter Students should be able to see that this planetarium does not show distances correctly.
