Describe four ways Venus is similar to Earth today. Describe four ways Venus is different from Earth today.
The four ways in which Venus is similar and different from Earth today.
Answer to Problem 1RQ
The four ways in which Venus is similar to Earth are similar mass and size, same average density, formed in the same part of solar nebula and similar orbits. It is different in having clockwise rotation, very dry surface, thick atmosphere and no measurable magnetic field.
Explanation of Solution
The four ways in which Venus is similar to Earth are similar mass and size, same average density, formed in the same part of solar nebula and similar orbits.
The diameter of Venus is
The four ways in which Venus and Earth are different are clockwise rotation, very dry surface, thick atmosphere and no measurable magnetic field.
Venus and Uranus are the only planets in the solar system that rotate in clockwise direction. The rest rotate in anti-clockwise direction. Venus’s surface is drier than Earth’s driest surface and a hundred times thick atmosphere than the Earth.
