Hi, my name is Eylene Pirez, and I'm an astrophysicist, and this is what is the layer of loose rocks and particles on the lunar surface of the moon. Well on the lunar surface we generally find something called the regolith. And this is actually quite important 'cause we find it in a lot of places in the solar system. We find it on earth, we find it on Mars, but the thing to keep in mind here is that the moon doesn't have an atmosphere, it doesn't have plate tectonics, so there's no erosion, there is no land form changing, changers, so everything that it, you know, came up during the formation period or during the bombardment, was still very much intact. So the moon is not a dynamic place, it's not changing. So when we look at the regolith, we want to look at the density of the regolith. This is about 1.4, 1.5 grams per cubic centimeter, fairly dense, and then this is covering the entire surface, and this the entire surface is, you can think of this as like fragmented rocks, and then you have the bedrock. Obviously there's some bedrock that's been broken off and is with the regolith, and this particles can range from 5 meters to 10 meters in size, so they're not that small either. And yeah, that's the loose rock that is found on the surface of a lot of terrestrial planets and moons, it's called the regolith. My name is Eylene Pirez, and I'm an astrophysicist, and this is the layer of loose rocks on the lunar surface.
