How does Mars' gravity compare to Earth's
about half of Earth's
about 1/3 of Earth's
about 1/4 of Earth's
about 1/10th of Earth's
Which of the following might explain Olympus Mons enormous size and "circus tent" like appearance and formation? Check all that apply
lack of active plate tectonics
lower surface gravity
low number of eruptions over millions of years
low viscosity lava
Which NASA space probe series had the first craft that went into orbit around Mars
Mariner
Voyager
Viking
Mars Pathfinder
Which hemisphere of Mars is more heavily cratered and has shield volcanos, extensive lava flows, valles, and canyons
western
northern
southern
eastern
What does the fact there are very few craters on the slopes of Olympus Mons suggest?
extensive lava flows
constant resurfacing from solar winds
it is geologically young
none of the above
Why does Mars' surface continually change from dark to light colors?
dust storms blow away light top layers and expose lower dark layers
CO2 frost settles and sublimes with the seasons
active volcano lava flows constantly change the surface
the surface colors stay constant and do not change
What is the likely origin of Crater A in this image of Ceraunius Tholus on Mars?
volcanic caldera sink hole
crater impact
volcanic vent
lava flooding
What is believed to be the cause of these wormlike trails in the slopes of Hellas planitia
dust devils
dry ice chunks rolling down the hill
liquid brines (salt water deposits) in the summer season
pulverized impact melt flowing
What do scientists think may be the cause of these fresh appearing gullies in a crater wall, as imaged by the Mars Global Surveyor?
dust devils
dry ice chunks rolling down the hill
recent liquid water flow
pulverized impact melt flowing
What has been recently exposed in an eroding slope on Mars that appears bright blue in this enhanced color view from the HiRISE camera on Mars Reconnaissance Orbiter
CO2 deposits (dry ice)
underground water ice
basalt lava deposits
none of the above
