Which of the following is the way that the planet Mercury is similar to the Moon?

Mercury is a planet much like the Moon. It has no atmosphere, and its surface is covered with circular im pact craters and huge, round basins. Most of Mercury looks much like the lunar highlands; apparently it was subjected to the same bombardment that shaped the Moon in primordial times.

Which of the following is a way that the planet Mercury is similar to the Moon quizlet?

Which of the following is a way that the planet Mercury is similar to the Moon? Its surface is heavily cratered.

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 is one important way in which both the Moon and Mercury are different from Earth quizlet?

The Moon is principally composed of silicate rocks, whereas Earth has more metals and volatile compounds. Earth has an iron core, but the Moon does not. Earth has liquid water in its surface layer, but the Moon does not. Mercury contains substantially more metals than the Moon, with a significant iron-nickel core.

How is the evolutionary history of Mercury similar to and different from the Moon’s?

Mercury’s evolutionary path was similar to that of the Moon for half a billion years after they both formed. Mercury’s volcanic period probably ended before that of the Moon. The absence of a lunar atmosphere and any present-day lunar volcanic activity are both consequences of the Moon’s small size.

Does Mercury rotate?

Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. However due to an orbital-rotational resonance ratio of 3:2, a fictitious observer on Mercury would see that a solar day from noon to noon would take about 176 Earth days to complete. (This is assuming an observer is not at one of the poles.

What causes Mercury’s 3 2 spin?

Mercury’s Spin-Orbit Resonance. Viewed from the Sun, Mercury exhibits a peculiar motion indeed! Over eons, its spin (rotation) and orbit have become synchronized by gravitational forces such that Mercury rotates on its axis three times for every two orbits. … The Sun can appear to stop in Mercury’s sky!

What type of surface feature is commonly found both on Mercury and on the Moon?

Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. This portion of the Moon is covered by numerous circular holes. These are impact craters, each of which was formed when an asteroid or comet collided with the Moon’s surface.

What are some ways Venus Earth and Mars are similar quizlet?

Venus, Earth, and Mars are similar in that they consist of rock and metal for the most part; they are terrestrial planets, closer in to the Sun than the jovian planets; all have atmospheres (although they are of different constituents and with different pressures); all have volcanic activity on their surfaces; and all …

How do the atmospheres of the Moon and Mercury compare quizlet?

How do the atmospheres of the Moon and Mercury compare? Neither body has a permanent atmosphere. … the Moon’s is similar to Earth’s crust, while Mercury’s is similar to the entire Earth.

Which statement about the rotation of Mercury & The Moon 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.

In what way is the moon similar to the Earth?

The composition of the Moon is much like that of the Earth. Its rocks are similar to Earth rocks and contain many but not all of the same minerals. However, the Moon has no atmosphere, it shows no trace of past or present life, and its rocks contain no water. The Moon rocks show that the lunar surface is very ancient.

What planet can come closest to the Earth in its orbit and look brightest in our skies quizlet?

This is confirmed by the fact that Mars appears at its brightest during this motion (due to it being at its closest approach to Earth) and is also on the opposite side of the sky from the Sun during retrograde motion.

Why did early astronomers think that Mercury was two separate planets?

Why did early astronomers think that Mercury was two separate planets? — Because Mercury can only be seen at sunrise or at sunset, early astronomers thought that one planet could only be seen at sunrise and the other planet could only be seen at sunset. You just studied 48 terms!

Do Mercury Venus and Earth have similar densities?

Mercury, Venus, and Earth have similar densities. The density of Mars is very similar to that of the other terrestrial planets. Venus can appear as a crescent through the telescope. Mercury’s rotation and revolution are an example of a 3:2 resonance.

How are Earth and the Sun alike and different explain two similarities and two differences?

The Sun and the Earth both have hotter core, i.e. there surface is much more cooler than that of its core. … The Sun, Moon and The Earth are somewhat spherical in shape. The Sun and the Moon have no change in weather, the weather is the same all the time.
