Question 1
Question
Venus is sometimes referred to as the "evening star" or the "morning star".
Answer
- True
- False
Question 2
Question
Which planet is Venus most similar to in diameter and mass?
Answer
-
Jupiter
-
Earth
-
Mars
-
Saturn
Question 3
Question
What is true about Venus' atmosphere?
Answer
-
It consists mostly of Carbon Dioxide (CO2), making up approximately 96% of the atmosphere.
-
The atmospheric pressure is 90% stronger than Earth's.
-
The atmosphere is extremely hot, due to an extreme or "runaway" greenhouse effect.
-
All of the above.
Question 4
Question
Because of Venus' thick atmosphere, night and day temperature only differ by a few degrees.
Answer
- True
- False
Question 5
Question
What is true about Venus' surface?
Answer
-
It experiences plate tectonics similarly to the Earth's, causing many long mountain ranges, large canyons, and volcanoes along edges of plate boundaries.
-
The surface of Venus is very different from Earth's. While it has many volcanoes, they did not form in a similar way to the Earth's volcanoes, suggesting that Venus' mantle does not experience convection.
-
The surface of Venus is mostly flat without any traces of volcanoes, mountains, or craters.
-
Venus' surface is mostly mountainous with many small crater impacts, though there is no trace of volcanoes.
Question 6
Question
What is unique about Venus' rotation?
Answer
-
Venus has a "retrograde spin", meaning it spins backwards on its axis in comparison to other terrestrial planets.
-
Venus rotates sideways on its axis.
-
Venus rotates quicker than any other planet in our solar system, given it the shortest day.
-
Due to "tidal locking" Venus' always has the same face pointed at the Sun.
Question 7
Question
Venus spins on its axis slower than any other planet in the Solar System, causing it to have extremely long days and nights.
Answer
- True
- False
Question 8
Question
At one point in time, Venus may have had liquid water, but what happened to it?
Answer
-
The water may have boiled away and sunlight broke down the H2O to allow hydrogen to escape.
-
The water froze due to the extreme cold Venus' experiencing during night.
-
The water became trapped in volcanic glass, causing "bubbles" in the rocks.
-
The water became trapped in cracks Venus' thick crust, so it is no longer present on the surface.
Question 9
Question
What caused Venus' weak magnetic field?
Answer
-
The interior of the planet is completely solid, making it impossible to generate anything but a residual magnetic field.
-
The interior of the planet lacks any iron, which is necessary to generate a magnetic field.
-
The dense atmosphere of the planet does not allow a magnetic field to form.
-
The slow rotation rate causes a the process for generating a magnetic field to weaken, causing a lack of a magnetic field.
Question 10
Question
What evidence is there that the surface of Venus was covered by giant flows of lava a few hundred million years ago?
Answer
-
The surface is still very hot.
-
The cracks present in the lava indicate its age.
-
Radioactive dating was used to determine when it cooled.
-
There are relatively few impact craters on Venus' surface.
