What is the fundamental reason that Mars has so little geological activity compared to Earth?
What’s the fundamental reason that Mars, unlike the Earth, has become virtually geologically dead? Its small size compared to Earth. Small size leads to less volcanic outgassing and greater atmospheric loss.
What is the primary reason why Mars lost its atmosphere quizlet?
CQ: Why did mars lose most of its atmosphere? Its atmosphere condensed onto the poles and froae into the soil bc mars is farther from the sun, it lost its atmosphere to space after losing its magnetic field, its small size prevented it from holding its atmosphere, its interior cooled so volcanic outgassing stopped.
Which of the following could explain why Mars today lacks a global magnetic field like that of Earth?
Assuming this is true, which of the following could explain why Mars today lacks a global magnetic field like that of Earth? … Mars’s interior has cooled so much that its molten core layer no longer undergoes convection. -Convection of the molten core is required for a global magnetic field.
Which of the following most likely explains why Venus does not have a global magnetic field like Earth quizlet?
Which of the following most likely explains why Venus does not have a global magnetic field like Earth? Its rotation is too slow.
Why does Mars have more extreme seasons than Earth?
Mars has an axial tilt more like the Earth’s than any other planet in our solar system. Mars undergoes seasons because of its eccentric orbit that carries it to widely different distances from the Sun, and because of its axial tilt which is similar to the Earth’s.
What is the fundamental reason that the Moon has more craters than Venus?
The moon’s surface is much more heavily cratered than Earth’s surface because ancient craters have already disappeared on Earth . They were worn away over time by water , wind , and other forces . Since the moon has no liquid water or atmosphere , its surface has changed very little .
What is the primary reason why Mars lost its atmosphere?
Solar wind and radiation are responsible for stripping the Martian atmosphere, transforming Mars from a planet that could have supported life billions of years ago into a frigid desert world, according to new results from NASA’s MAVEN spacecraft.
Why did Mars lose most of its atmosphere?
NASA pointed out that Mars had a thick atmosphere shortly after it was formed, and most of the composite in its atmosphere was carbon dioxide. However, due to the lack of magnetic field protection, the majority of the Martian atmosphere was destroyed by the strong solar wind, and escaped to space (Carlisle, 2015).
How do seasons on Mars differ from seasons on Earth?
Mars has four seasons just like Earth, but they last about twice as long. … That’s different from Earth, because our planet has a near circular orbit. Winter in the southern hemisphere is worse, because Mars is the farthest away from the Sun and moves more slowly in its orbit.
