One principle you will learn is that more craters on a surface indicate that the surface is older. But, the Moon and Mercury have more craters than Earth, Mars and Venus. So, are the Moon and Mercury older than the Earth, Mars and Venus? If so, how does the formation of the solar system explain that? If not, why do Mars, Venus and Earth have so few craters as compared to Mercury and the Moon?
Homework Answers
No, the Moon and Mercury are not older than the other terrestrial planets of the solar system.
The Mercury and the moon lack an atmosphere which on other planets has eroded, weathered or destroyed the meteorites by wind, water or due to friction. So that is the reason why we can see many craters on moon and mercury.

1. The atmosphere of Venus is 90 times more massive (based on the surface pressure) than Earth, yet Mercury has almost no atmosphere. Explain why the atmospheres of these two planets are so different. Use at least three factors we discussed in class to explain the differences (gravity, surface temperature, composition). Don't be vague - be specific - which will require you to do some research into the characteristics of each planets' atmosphere. (6)

The closest planet to the Sun, Mercury, has a diameter that is a little more than 1/3 that of the Earth, yet the density of Mercury is nearly equal to Earth’s (98.4% of Earth’s density). Question 31: [1] If Mercury is so much smaller than Earth yet has such a similar density, what does this indicate about the interior of Mercury? Question 32: [2] Why is it that the metallic core of a rocky body such as Earth is primarily...

1. It turns out that Mercury and Mars have the same gravity as one another – that is, you would weigh the same on the surface of Mercury as you would on the surface of Mars, despite the fact that Mercury is smaller. Why is this the case? 2. that even if Venus used to have oceans (and maybe even life), there is no way for us to tell today whether this was ever the case. Thinking about what we...

The Aliens decided to use the basis given in green and you are using the basis given in blue (See below). The aliens sent you their coordinates for the planets Mercury, Venus, Earth, and Mars, in their coordinate system. You also...

The moon does not fall to earth because: The moon is beyond the main pull of Earth's gravity. The moon is pulled by the sun and planets as well as by Earth. The gravitational force provides the required centripetal force for the moon to have its tangential speed around the Earth. The net force on the moon is zero. The moon is in earth's gravitational field. Question 3 (4 points) The tallest mountain in our solar system is Mt. Caloris...

Temperatures on planets. To a good approximation, stars and planets emit their energy like a black body, which means the energy flux (energy per unit area and per unit time) at the solar surface (radius R_s = 7 times 10^8 m) is given by F = sigma_SBT^4, where sigma_SB = 5.67 times 10^8 W m^-2 K^-41 is the Stefan-Boltzmann constant. [Remember, energy per unit time is power and it- is...

Saturn's largest moon, Titan is actually larger than the planet Mercury. It is also one of the few bodies in the solar system that has a dense atmosphere. Data from the Voyager 1 probe indicates that the atmospheric pressure on Titan's surface is about 1.60x10^5 Pa, even though free-fall acceleration at Titan's surface is only 1.36m/s^2. Assuming that Titan's atmosphere has a uniform density of 2.32kg/m^3, at what height above the surface is Titan's atmospheric pressure equal to 1.01x10^5 Pa?
