The seafloor crust is younger than the continental crust.
Craters on the moon are not volcanic, they are impact craters.
Io did have impact craters but they have all been buried in lawa flows
The theory is that these are impact craters of meteors.
First, we have a nice thick atmosphere that deals with many meteors. Secondly, weathering and erosion erase the marks fairly quickly.
Since the Earth's crust is a dynamic surface that is controlled by convection in the Earths core, the plates on which the surface lies are moving, called plate tectonics. This tectonic motion produces subduction which recycles and changes the Earths surface resulting in a ever changing and recycled surface, that does not preserve impact craters. Also, erosional and weathering processes erode away the higher parts of craters leaving no clear marking of craters over a long period of time.
Impact craters.
Impact craters occur where objects impact on a solid surface.
Impact craters on the moon have no water/weather to erode the craters away, but on Earth the erosion erases the craters over time.
Craters on the moon are not volcanic, they are impact craters.
Mercury has impact craters but not volcanoes.
Io did have impact craters but they have all been buried in lawa flows
Meteor craters.
The craters on the Moon are considered to be impact craters, caused by meteoroids striking the Moon.
The theory is that these are impact craters of meteors.
First, we have a nice thick atmosphere that deals with many meteors. Secondly, weathering and erosion erase the marks fairly quickly.
