Chapter 9 Flashcards
What do all terrestrial planets have roughly in common
They have similar densities and similar sizes
What is Mercury’s rotation rate
It’s day and year is in a 3:2 resonance. Rotates three times while going around the sun twice.
Does mercury have an atmosphere
No
Does Venus have an atmosphere
Yes, extremely dense.
Does mars have an atmosphere
Yes, similar to earth’s but very thin
What are the clouds of Venus made of
Sulfuric acid droplets with traces of water
What does mars and Venus atmosphere mainly consist of
Carbon dioxide
What is caloris basin
The largest crater on mercury almost 1300km in diameter
Can we find lava in mercuries old craters
Yes, it is congealed in many of them
What are scarps
They are cliffs that formed as mercury shrank and wrinkled like an apple
Is venus comparable to earth
In its mass and diameter but it’s surface and atmosphere are very different
What is the crown like structure on Venus called
The corona
What is Venus’s largest impact crater called
Mead
Does mars have polar caps
Yes it does
What is the tharsis bulge on mars
It is the size of North America and 10km above surroundings
What are the north and south hemispheres of mars like
The north us rolling volcanic terrain and the south is heavily cratered. The north is younger than the south
What is Vallis marineris
It is a rift running along the equator that is 4000 km long
What is Olympus mons
It is the largest volcano in the solar system, it is on the surface of mars, it is 25km high and 700km in diameter
Was there running water on mars
Yes, it is presumed that there was due to runoff channels and it is possibly underneath the surface of mars in permafrost
What is primary and secondary atmosphere on a planet
Primary is one that happened at formation and was quickly lost while secondary is one that came from volcanic activity
Does Venus have a greenhouse effect
Due to its thick and dense atmosphere it has a runaway greenhouse effect and its surface is 730 K
Does mercury have a strong magnetic field
It has a very week remnant one
Does Venus have a magnetic field
No, probably due to its slow rotation
Do Venus or mars show evidence of tectonic activity
No
