Why are there no visible craters on Io?
Why are there no visible impact craters on the surface of Io? They have been covered up by Io's active surface geology.
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 don't we see impact craters on the surface of Io quizlet?
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.
Why are no craters seen on Io and few seen on Europa?
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.
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 is Jupiter's moon Io not completely tidally locked?
The tidal force from Jupiter changes with distance, so Io is constantly being ``stretched and squeezed'' by Jupiter -- the tidal bulges change elevation due to the changing tidal force.
What makes the surface of Io appear red and orange?
Io's unusual red and orange colors come primarily from sulfur, which condenses on the surface after being outgassed by the volcanoes. Although there is no direct evidence of tectonic activity on Io, scientists feel confident it exists since the processes that fuel volcanism also fuel tectonics.
Why does the Moon have more impact craters than Earth does?
Why does the Moon have so many craters while Earth has so few? On Earth, impact craters are harder to recognize because of weathering and erosion of its surface. The Moon lacks water, an atmosphere, and tectonic activity, three forces that erode Earth's surface and erase all but the most recent impacts.
Why is Io more volcanically active than our moon?
Why is Io more volcanically active than our moon? Io has a different internal heat source.
Why does Europa have so few impact craters quizlet?
Why does Europa have so few impact craters? Recent activity in its icy crust has erased most craters. Why might life exist on Europa? It may have a liquid ocean of water below its icy crust.
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.
Why are there so few impact craters on the surface of the Earth compared to the Moon quizlet?
There are so few craters on the Earth because most have been destroyed due to plate tectonics and erosion. There are so few craters on Venus because lava flows have filled in the craters.
