Which of the following is a 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.
How is Mercury similar to planets?
Along with Venus, Earth, and Mars, Mercury is one of the rocky planets. It has a solid surface that is covered with craters. It has no atmosphere, and it doesn’t have any moons. … Because it’s the closest planet to the sun, it doesn’t take very long to go all the way around.
What is one way Mercury is similar to Earth?
Much like Earth, Mercury is a terrestrial planet, which means it is composed of silicate minerals and metals that are differentiated between a solid metal core and a silicate crust and mantle. For Mercury, the breakdown of these elements is higher than Earth.
Does Mercury have Maria?
1) There are few maria on Mercury and they are small. No large impact era like the Moon. Therefore, Mercury must have cooled faster. 2) Cratering is less heavy, more plain region between craters.
Is Mercury a cold planet?
Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
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 evidence do we have that Mercury has a partially molten metallic core quizlet?
What evidence can you give that Mercury has a partially molten, metallic core? Mercury has a magnetic field. Also, radar observations show that the surface shifts back and forth slightly, requiring at least a molten outer core. Why is it not surprising that there is no evidence of plate tectonics on Mercury’s surface?
What do Mercury and Earth have in common?
Mercury and Earth a both inner planets. They both orbit around the sun, however they have different time periods. Mercury and Earth are rocky planets, and consists of land and rock. Earth’s orbital period is 365 days, and takes twenty-four hours to turn a complete day and night.
Why is Mercury the closest planet to Earth?
Essentially because Mercury is closest to the Sun, when taking an average over time, Mercury is the closest planet to the Earth, and—in that measure—it is the closest planet to each of the other planets in the Solar System.
How is Mercury compared to Earth?
Mercury has a diameter of 3,032 miles (4,879 km) making it a little more than one third the size of Earth. If Earth were the size of a baseball, Mercury would be about the size of a golf ball.
What type of planet is Mercury?
Mercury is a rocky planet, also known as a terrestrial planet. Mercury has a solid, cratered surface, much like the Earth’s moon.
Why is Mercury a planet and not Pluto?
It must be large enough that its gravity has pulled it into a spherical shape, and also must dominate and gravitationally clear its orbital region of most of all other objects. It does not clear the orbital zones of other planets and therefore does not meet the standard for being called a planet.
Can you see Mercury from Earth?
Yes, Mercury is one of the five planets (excluding Earth) that you can see relatively easily with the naked eye. It’s the most difficult of those five planets but it is certainly possible to see without a telescope.
