What is the primary cause of erosion on the Moon?
What is the primary cause of erosion on the Moon? Meteoroid impacts have battered the surface of the Moon for billions of years and are the primary cause of erosion.
At which phase of the Earth’s moon would you expect to find extremely high and low tides?
The highest and lowest tides occur on the full or new moon phases.
Which statement about the rotations of the Moon and Mercury is false?
Which statement about the rotations of the Moon and Mercury is FALSE? Like our Moon, Mercury does not rotate at all, keeping the same side facing the Sun.
What theory of the Moon’s origin is favored by most astronomers today?
The giant-impact hypothesis is currently the favored scientific hypothesis for the formation of the Moon. Supporting evidence includes: Earth's spin and the Moon's orbit have similar orientations.
Why does erosion not occur on the Moon?
The Moon has almost no erosion because it has no atmosphere. That means it has no wind, it has no weather, and it certainly has no plants. Almost nothing can remove marks on its surface once they are made.
Does the Moon have weathering and erosion?
However, the surface of the Moon doesn't change like it does on Earth. Because the Moon has no atmosphere and no liquid water, weathering, erosion, and deposition don't take place. Landslides, earthquakes and volcanoes also don't happen on the Moon either.
Which of the following is the most likely moon phase for when the Earth is experiencing a neap tide?
Neap tides occur during the first and third quarter moon, when the moon appears "half full."
Why are high tides on Earth greatest when the moon is in position A and in position E?
Q. Why are high tides on Earth greatest when the Moon is in position A and in position E? The moon is closer to the Sun.
How do the atmospheres of the Moon and Mercury compare quizlet?
In size, Mercury is intermediate between: the Moon and Mars. How do the atmospheres of the Moon and Mercury compare? Neither body has a permanent atmosphere.
What is one important way in which both the Moon and Mercury are different from Earth?
Both Mercury and the moon have surfaces, or crusts, composed almost entirely of rock and pocked with craters. Unlike Earth, which has an element-rich atmosphere in which incoming meteorites often burn, Mercury and the moon have thin atmospheres, called exospheres, that hold little gas and offer little insulation.
What are the theories of Moon’s Origin Earth’s moon )? What are the statement of those theories?
The prevailing theory supported by the scientific community, the giant impact hypothesis suggests that the moon formed when an object smashed into early Earth. Like the other planets, Earth formed from the leftover cloud of dust and gas orbiting the young sun.
Why was the capture theory for the origin of the Moon rejected?
Capture theory–The Moon was captured by the Earth like many of the moons of Jupiter. This theory failed because: A captured moon would follow an elliptical orbit. However, the Moon follows an almost circular orbit.
Why has the Earth remained geologically active compared to the Moon?
Earth has an atmosphere, oceans, and water flow. Moon has no erosion and earth does.
Why is there no weathering on the Moon?
Lunar surface is continuously bombarded by the solar wind plasma because the Moon has neither an atmosphere nor a global intrinsic magnetic field that could deflect the plasma flow around it. The impacting solar wind particles modify the properties of the surface and this process is known as space weathering.
During which phase does Earth see more than half of the moon’s surface?
Waxing gibbous Waxing gibbous More than 1/2 of the Moon's illuminated surface can be seen from Earth. Each day the gibbous appears a little thicker. Person A does not see the moon at sunrise. Person B does not see the moon at noon.
Why does the moon’s gravity have a greater effect on Earth’s ocean tides than the sun’s gravity?
Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
Does the moon or the sun have a greater influence of the tides that we experience on Earth?
Based on its mass, the sun's gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth. If tidal forces were based solely on comparative masses, the sun should have a tide-generating force that is 27 million times greater than that of the moon.
How does the atmospheres of the Moon and Mercury compare?
Despite their 'airless' appearance both Mercury and the Moon have thin tenuous atmospheres. With no detectable gases the Moon appears to be atmosphere-free. The Moon as seen from a view above the majority of Earth's atmosphere. … The radiation and solar wind fluxes are similar between the Earth and Moon.
Which of these criteria best explains why the Moon and Mercury do not have atmospheres?
Concept of escape speed to explain why the Moon and mercury have no atmospheres. More massive objects have better chance of keeping atmospheres bc the more massive an object, the greater the escape speed.
Why does the Moon almost have no erosion?
The Moon has almost no erosion because it has no atmosphere. That means it has no wind, it has no weather, and it certainly has no plants. Almost nothing can remove marks on its surface once they are made.
Which theory states that the Earth and the moon formed at the same time from the nebula?
The Condensation Theory: This theory proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the Moon formed in orbit around the Earth.
What is the giant impact hypothesis for the origin of the moon quizlet?
What is the giant impact hypothesis? The giant impact hypothesis states that the Moon was created out of the debris left over from a collision between the Earth and a Mars-sized body (Theia), around 4.5 Ga.
What is the Moon theory?
The prevailing theory supported by the scientific community, the giant impact hypothesis suggests that the moon formed when an object smashed into early Earth. Like the other planets, Earth formed from the leftover cloud of dust and gas orbiting the young sun.
Why do the Earth and moon have different surfaces?
This is because as the Moon orbits the Earth, one side of the Moon is always facing the Sun. As the Moon's orbits, we see the Moon in different positions, and in these different positions we see varying amounts of the surface lit by the Sun. The lunar phase depends on the Moon's position in orbit around the Earth.
Why is the Moon not tectonically active?
Tectonic plate motions in Earth are driven by convection in the mantle—the solid mantle actually moves at rates of a few centimeters a year. The Moon's mantle, too cool to move easily, has no convection and no active tectonic plate motions.
Is the Moon geologically active or dead?
We tend to think of the moon as the archetypal "dead" world. Not only is there no life, almost all its volcanic activity died out billions of years ago.
What characteristics needed for weathering and erosion does the Moon lack?
On Earth, impact craters are harder to recognize because of weathering and erosion of its surface. The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth's surface and erase all but the most recent impacts.
Which true about weathering in the Moon?
Given that weather is created by the interactions among air, water and sunlight, the moon has no weather. So the moon technically has no weathering.
When Earth is between the Moon and the Sun the Moon’s phase is most likely a?
A full Moon occurs when the Moon has moved in its orbit so that Earth is “between” the Moon and the Sun.
How does the Moon’s appearance change as the Moon revolves around Earth?
The Moon doesn't emit (give off) light itself, the 'moonlight' we see is actually the Sun's light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape. In actual fact, it's just our view of it that's altering…
