Relationship between Earth, Sun and Moon; 2. As The Earth Turns • The rotation of the. Actually there is no such thing as tide. Yes, you heard it right. Tide is merely our perception of rise and fall of sea level because of rotation of Earth inside the.
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. Nick Rose Seasons The Earth's axis of rotation is tilted in relation to the ecliptic plane, an imaginary surface through Earth's orbit around the sun.
This means the Northern and Southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons. The tilt of Earth's axis is about As such, the moon virtually has no seasons.The Relative Size of the Earth, Moon and Sun
This means that some areas are always lit by sunlight, and other places are perpetually draped in shadow. The Greeks also believed the dark areas of the moon were seas while the bright regions were land, which influenced the current names for those places — "maria" and "terrae," which is Latin for seas and land, respectively. The pioneering astronomer Galileo Galilei was the first to use a telescope to make scientific observations of the moon, describing in a rough, mountainous surface that was quite different from the popular beliefs of his day that the moon was smooth.

This spurred a series of uncrewed missions by both the Soviet Union and the United States to observe the moon's surface. Many of these first probes were failures or only partially successful. However, over time, these early probes returned information about the moon's surface and geological history. Luna 2 was the first spacecraft to impact the moon in The first soft landing was achieved inby Luna 9.
The United States sent astronauts to the moon's orbit and surface in the s and s. The first mission to the moon was inwhen the Apollo 8 astronauts orbited it.
InApollo 11 landed the first astronauts on the moonundoubtedly the most famous of NASA's achievements, followed by five more successful missions and one, Apollo 13, that didn't make to the moon.
Their efforts returned lbs. It remains the only extraterrestrial body that humanity has ever visited. Scientists continue to study the rocks, and have made new discoveries as technology improved.
For example, inwater was found in samples from Apollo 15, 16 and 17 — an interesting find given that previous analyses showed these rocks were quite dry. While crewed lunar missions concluded inrobotic exploration continued.
The Soviet Union remained active in robotic lunar exploration through the s and s, even as the Apollo astronauts landed there.

The first lunar sample return mission took place with Luna 16 in Septemberafter multiple failed attempts with other missions. 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.

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. Draw a picture that shows how the Earth, Moon, and Sun are lined up during the new moon phase. Why are neap tides less extreme than spring tides?
