How come there are so many craters on the moon but very few (negligible)on the earth?
There are soooooo many craters on the Earth! Just as many as on the moon! Too many to count in fact. You can see craters left on the moon and other planets because their geological processes have stopped millions of years ago. You can rarely see Earth’s craters due to things like erosion, soil redeposition, tectonic plate movement, and volcanic deposition. Basically, because the Earth’s surface is constantly moving about, it covers up the crater caused by the meterological impact.
that’s just the point, see how many craters on tiny moon, and how many impacts, can you imagine how many times the Earth has been hit over time (but because of erosion from wind, rain, and weather can’t always see, sometimes only the large ones, that impact straight and cause big crater, but sometimes glancing blow that doesn’t produce as big a crater but can still cause a lot of damage and affect our climate). sometimes can have multiple hits at one time like Shoemaker and can cause just as much damage if not more than a large singular, or may break apart and cause multiple impacts. because can move quickly and are considered “dark matter” that can’t usually be seen in advance, and can even come from outside our solar system, good luck in catching in advance. may have one second warning once see hit atmosphere WATCH OUT!!! HERE COMES ANOTHER ONE!!!! DUCK AND COVER!!!!!
