E. 243 days, even though the Earth's tidal pool is not evolved.
Venus orbits around the Sun in 225 days, How long dies it take to rotate on its axis.
D. The Magellan space probe.
Our most detailed maps of Venus come from:
D. Magellan radar data and radar observations of the planet from Earth.
Our best data about the surface topography of Venus has come from:
The orbit that gave us the most detailed map of Venus to date was.
C. Is much higher than on Earth.
The atmospheric pressure on Venus:
D. It has raised the surface temperature.
What is the result of the Greenhouse effect on the surface environment of Venus?
D. Carbon Dioxide.
What is the main constituent of the atmosphere of Venus?
B. 36 days before or after inferior conjunction, appearing as a large crescent.
Venus is highest as seen from Earth:
A. 0.3 AU
At closest approach, Venus is about how far from Earth?
B. Superior conjunction.
Venus' full phase occurs when Venus is at:
B. They have similar masses and sizes.
Why is it reasonable to conclude that the internal structure and evolution of Venus are basically Earth like?
B. Takes longer that its orbit around the sun.
A. Rotation in its axis is retrograde.
Through radar observations, it was found that Venus'
E. All the above are correct.
Why does Venus appear so bright to the eye?
B. Size, density, and surface gravity.
Earth and Venus are often called sister planets; in which way are alike?
D. Presents the same side to earth at each closest approach.
Because of its slow rotation period, Venus;
D. About 3.5 years
The synodic period of Venus is about about how many years?
A. Just a little but less than Earth.
Venus is only a little bit (5%) smaller than Earth, and its density is only slightly less the Earth's. Therefore its mass is:
C. Venus to complete a full cycle of phases.
The synodic period of Venus is the time it takes for:
B. Radar observations from Arecibo
The surface of Venus can be observed with:
E. It sits above a hot spot in the planets mantle.
Which of the following characterizes a shield Volcano..
C. There are two continent sized uplands.
Which statement is true of Venus' surface?
D. A far greater percentage of its surface in raised continents.
Compared to the Earth, Venus has:
D. Venus always presents the same force to Earth at inferior conjunction.
In the time between two closest approaches to Earth, Venus rotates almost exactly fine relative to the sun. The consequence of this is that.
A. 5:1, with the Earth always closest to the same side of Venus when they pass.
What resonance exist between Venus' rotational period and its synodic period?
