Why are no craters seen on Io and few seen on Europa quizlet?
Why are no craters seen on Io and few seen on Europa? On Europa, the icy surface is constantly shifting and if it is struck, it just becomes water and freezes again or becomes gas. Io is very volcanic, so it is constantly being resurfaced.
Why are there no impact craters on the surface of Io quizlet?
a mixture of rock and ice. Why are there no impact craters on the surface of Io? Io did have impact craters but they have all been buried in lava flows. a natural consequence of tidal forces acting on the moons.
Why are there no impact craters on the surface of Io Why are there no impact craters on the surface of Io?
Why are there no impact craters on the surface of Io? A) Jupiter's strong gravity attracted the planetesimals more strongly than Io, and thus none landed on its surface.
Why are there no craters seen on Io and few seen on Europa?
Why are no craters seen on Io? The volcanoes and geologically active mountains on Io erase craters from the surface. Why are few craters seen on Europa? The icy crust of Europa shifts atop an underlying ocean of water, which erases craters from the surface.
Why does the moon Io have no impact craters?
Question 1: You mentioned that there are no impact craters on Io, is that because of Jupiter's large gravitational pull that prevents smaller bodies from impacting Io? No, it is because Io's active volcanism covers over craters very rapidly, geologically. The resurfacing rate is ~1 cm/yr.
Why are numerous impact craters found on Ganymede and Callisto but not on Io or Europa?
Why are numerous impact craters found on Ganymede and Callisto but not on Io or Europa? All of them have had many impacts over the past billions of years. But the debris from Io's active volcanoes has covered old impact craters. Liquid water from inside Europa causes the ice to move, erasing many of the impact craters.
Can you see Io from Earth?
Io is one of the four so-called Galilean moons of Jupiter, along with Europa, Ganymede, and Callisto. These larger moons, discovered by Galileo Galilei in 1610, are all visible from Earth with a small telescope.
Why don't we see transit events for most stars that have been found to have planets?
Why don't we see transit events for most stars that have been found to have planets? Most of the planets orbit the star without ever getting directly in between Earth and the star. Suppose you monitor a large number (many thousands) of stars over a period of 3 years, searching for planets through the transit method.
What does the surface of Io look like?
Io's volcanism is responsible for many of its unique features. Its volcanic plumes and lava flows produce large surface changes and paint the surface in various subtle shades of yellow, red, white, black, and green, largely due to allotropes and compounds of sulfur.
Why do Jupiter's moons Io and Europa have so few visible craters?
The Galilean moon closest to Jupiter is Io. Io has a iron-nickel core surrounded by a rock shell that extends all the way to the surface. Io has no impact craters even though it has a rocky, solid surface. The surface must be very young because something has erased the impact craters.
Would you expect to find more impact craters on Io or Callisto Why?
[10 pts] Would you expect to find more impact craters on Io or Callisto? Why? More on Callisto. Io is so volcanically active, it erases or covers over all impact craters in a very short period of time.
Which of the features is seen on the surface of Europa?
Slightly smaller than Earth's Moon, Europa is primarily made of silicate rock and has a water-ice crust and probably an iron–nickel core. It has a very thin atmosphere, composed primarily of oxygen. Its surface is striated by cracks and streaks, but craters are relatively few.
