What is the effect of the tidal coupling between Earth and the moon?

The Earth raises tidal bulges on the moon. As the moon rotated through these bulges, internal friction slowed the moon’s rotation until it achieved tidal coupling.

What do the vesicular basalts tell you about the lunar surface?

What do the features of vesicular basalts tell us about the evolution of the lunar surface? The holes were once gas bubbles in the molten material, which means that the molten material was not under high pressure, and likely on the surface. Has tectonics occurred on the moon?

When our Earth becomes tidally locked with the Moon which of the following statements will be true?

When our Earth becomes tidally locked with the Moon, which of the following statements will be true? –The Moon will always be visible only from one side of the Earth.

What evidence would you expect to find on the Moon if it had been subjected to plate tectonics?

What evidence would you expect to find on the Moon if the Moon had been subjected to plate tectonics? There would be volcanos and mountains.

How does the force of gravity cause tidal coupling between celestial objects?

How does the force of gravity cause tidal coupling between celestial objects? The gravity of the more massive object raises tidal bulges on the smaller object. Friction in the bulges slows the smaller object until it rotates once per each orbital period.

How do astronomers know whether lunar highlands or lunar maria have older surfaces?

How do astronomers know whether lunar highlands or lunar maria have older surfaces? The presence of many more craters means that there has been more time for impacts in the highlands, so they are older surfaces. The moon’s craters Copernicus and Tycho both have circular rims with a central peak.

What do astronomers generally believe about the origin of Mars’s moons?

What do astronomers generally believe about the origin of Mars’ moons? They formed elsewhere and were captured at a later time. Why does Mars have seasons similar to the Earth? Mars’ rotational axis is tilted like the Earth’s.

What do astronomers generally believe about the origin of Mars’s moons quizlet?

What do astronomers generally believe about the origin of Mars’ moons? They formed elsewhere and were captured at a later time. Why does Mars have seasons similar to the Earth? Mars’ rotational axis is tilted like the Earth’s.

Which of these Galilean satellites is most geologically active?

appear very bright because fresh ice is very reflective. appear dark in color with many impact craters. Which of these Galilean satellites is most geologically active? of Saturn.

What observational techniques allows astronomers to determine that Venus is rotating backwards?

What observational technique allows astronomers to determine that Venus is rotating backwards? Doppler shift of radio signals bounced off Venus’ equatorial regions.

Why does Venus rotate backwards?

An explanation for the backward, or retrograde, rotation is not certain. A long-held theory is that Venus once rotated as the other planets do, but was struck billions of years ago by a planet-size object. The impact and its aftermath caused the rotation to change directions or flipped the planetary axis.

Can Venus be seen from Earth?

Observe Venus transiting the meridian

Venus orbits one step inward from Earth. So we always see it near the sun in our sky, and, generally speaking, after sunrise it’s hard to see. But Venus is up there, every day, following or leading in the path of the sun across our sky.

How does Venus period of rotation compare with its period of revolution?

The period of rotation of Venus on its own axis is about 243 Earth days, while the period of revolution of Venus around the Sun is about 225 Earth days. Moreover, Venus spins in backwards direction when compared to most other planets. This means that the Sun rises in the West and sets in the East at Venus.

How is planet Earth similar and different from Venus and Mars?

Mars and Venus are the two terrestrial planets most similar to Earth. It has 81% the mass of Earth, while Mars only has 10% the mass of Earth. The climates of Mars and Venus are very different, and very different from Earth as well. Temperatures on the surface of Venus average 461 °C across the entire planet.

Which planet rotation period is greater than revolution period?

Venus

Venus: Its atmosphere is approximately 92 times dense than that of Earth. It takes 243.025 Earth days to rotate around its axis 224.65 Earth days to revolve around the sun. Making it the only planet whose period of rotation is longer than the period of revolution around the sun.

Which planet has a rotation period closest to that of Earth?

While earth takes 365 days to make one circuit, the closest planet, Mercury, takes only 88 days.
The Days (And Years) Of Our Lives.

What affects rotation period?

I found that velocity, acceleration, and radius are the most important factors in explaining rotation periods. The effect of mass may be rather on influencing the size of the radii of planets. That is, the larger the mass of a planet, the larger its radius.

What affects planet rotation speed?

The speed a planet rotate depends on the angular momentum it has after forming. This is influenced by a host of factors, from the composition of the planet, to its distance from the star and the gravity it experiences as well as any impacts it experiences such as comets hitting it.

What does Earth’s rotation cause?

The positions of Earth and the Sun over the course of a 24-hour rotation cause sunrise, sunset, day, and night.

Why does the Earth Cannot rotate upright?

Bottom line: We don’t feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.

Why does it take 24 hours for the Earth to rotate?

The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal day.

Does the Moon rotate?

It made so much sense now! The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. If the moon were to rotate quickly (several times each month) or not rotate at all, Earth would be exposed to all sides of the moon (i.e. multiple different views).

Does sun rotate?

The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun’s rotation axis is tilted by about 7.25 degrees from the axis of the Earth’s orbit so we see more of the Sun’s north pole in September of each year and more of its south pole in March.

What would happen if the moon was closer to the Earth?

If the Moon got much closer, say 20 times closer, it would exert a gravitational force 400 times greater than what we are used to. A mighty tidal bulge would be created, hitting the land and causing great flooding, with cities such as London and New York disappearing under water.
