Describe Four Ways Venus Is Similar To Earth Essay

1) Describe four ways Venus is similar to Earth today. Describe four ways Venus is different from Earth today.

Similarities: Both are similar in shape, with similar equatorial diameters. They have almost equal masses. They have almost the same density. They both come from the same part of the solar nebula.

Differences: Venus has a slower rotation than Earth. Earth has a stronger magnetic field than Venus. Venus’s atmosphere is mostly made up of carbon dioxide, while Earth’s carbon dioxide density is lower. Venus’s surface temperature is as high as 470°C and Earth’s temperature is much lower.

2) Why might you expect that Venus’s surface conditions should resemble Earth’s more than they do? One would expect more resemblance, because both

The cratering record is evidence that Venus resurfaced within the past half-billion years. In the most recent cratering, Venus destroyed older craters. Geological conditions covered much of the older craters, older sediments also evolved. Studies suggest that the resurfacing occurred in the past half-billion years.

11) Describe four ways Mars is similar to Earth today. Describe four ways Mars is different from Earth today.

Similarities: Both are terrestrial planets. Both have iron and nickel in their core. Mars surface temperature may be Earth like. A Martian day is only 40 minutes longer than an Earth day.

Differences: Due to its core, Earth has extreme magnetic field. Mars field is not too magnetic. Mars’s atmosphere has less density, similar to 1% of Earths atmosphere. Earth has more density than Mars.

12) How are today’s atmosphere of Venus and Mars similar? How are they different?

Similarities: The atmospheres of both have a lot of carbon dioxide. Micrometeorite impacts are avoided in both atmospheres.

Differences: Venus’s atmosphere is much more dense, while Mars’s atmosphere is thin. Most water in Venus is in gas form in its atmosphere, while not in
