We consider water fundamental to life, so scientists think that searching for evidence of water on Mars can bring us closer to finding evidence of life there. But could other elements be more fundamental to life on Mars? What other things do you think we should consider in our future investigations?
2.
What is present on Mars?
Correct Answer(s)
A. Cold temperatures
D. Radiation
Explanation
If you move to Mars you will need a high tolerance for cold, loneliness and radiation; a lifetime supply of breathable air and food; and definitely water.
3.
To travel to Mars, you will have to be a millionaire. A spaceship will probably cost about a few hundred million dollars.
Correct Answer
B. False
Explanation
a multibillion spaceship is more probable.
4.
The chances are high that there used to be oceans and rivers on Mars:
Correct Answer
B. True, about 4 billion years ago.
Explanation
"An ocean view? Uh, bad news on the last one. You’re about 4 billion years late."
5.
Which part of Mars has lower elevation and once had oceans?
Correct Answer
C. Northern hemispHere
Explanation
The northern hemisphere of Mars is believed to have lower elevation and once had oceans. Evidence from ancient river channels and sedimentary rock formations suggests that water flowed and pooled in this region. Additionally, the presence of features like dry river beds and remnants of ancient shorelines further support the theory that the northern hemisphere of Mars was once covered by oceans.
6.
Which part of Mars' surface seems older?
Correct Answer
A. Southern hemispHere
Explanation
The correct answer is the Southern hemisphere. This is because the Southern hemisphere of Mars has a higher density of impact craters, which indicates that it has been exposed to space debris for a longer period of time. The presence of more craters suggests that this region of Mars' surface is older compared to other parts of the planet.
7.
Mars has a surface similar enough to what we have on Earth, so that we could do research on Earth before moving to Mars. What surface is it?
Correct Answer
C. Deserts
Explanation
Mars has a surface similar to deserts on Earth. Deserts are characterized by dry and arid conditions, with limited vegetation and sparse water resources. Mars also has a dry and barren landscape with a lack of surface water and vegetation. This similarity makes deserts on Earth a suitable analog for studying and conducting research on Mars, as it can provide insights into the challenges and conditions that humans may face when exploring or colonizing the red planet.
8.
TARs are features that are only seen on Mars. What is the best definition of TARs?
Correct Answer
C. Crestless sand dunes up to 15 meters high
Explanation
TARs are features that are only seen on Mars. Crestless sand dunes up to 15 meters high are the best definition of TARs.
9.
What is the major natural hazard on Mars?
Correct Answer
C. Dust storm
Explanation
The major natural hazard on Mars is dust storms. Mars experiences frequent and intense dust storms that can cover the entire planet for weeks or even months. These dust storms are caused by strong winds that lift and suspend fine dust particles in the atmosphere, reducing visibility and potentially posing a risk to any human or robotic missions on the planet's surface.
10.
Why is Mars red? The red color of Mars is the result of ________ rusting. The rocks and soil were eroded by wind and the dust was blown across the surface.
The ________ within the dust reacted with oxygen, producing a red rust color.
Correct Answer
iron
iron
Explanation
The red color of Mars is due to the presence of iron in the dust on its surface. When the iron reacts with oxygen, it forms a red rust color, giving Mars its distinctive red appearance. The rocks and soil on Mars were eroded by wind, and the dust containing iron was blown across the surface, contributing to the overall redness of the planet.
11.
How tall is the largest volcano in our solar system?
Correct Answer
C. 25 km
Explanation
The largest volcano in our solar system is 25 km tall.
12.
Like on Earth, there are canyons on Mars.
Correct Answer
A. True
Explanation
The statement suggests that there are canyons on Mars, similar to Earth. This implies that Mars, like Earth, has geological formations that include deep, narrow valleys. This is supported by scientific evidence and observations made by various Mars missions, such as the presence of Valles Marineris, which is a system of canyons on Mars that is even larger than the Grand Canyon on Earth. Therefore, the statement is true.
13.
Which color are sunsets on Mars?
Correct Answer
A. Blue
