The most meteoite material that people have dated stems from the time when the solar system formed and stems from bodies that never managed to grow the size of planets.
When people date materials that are that old, they use techniques that tell them when the material solidified for the last time either from a homogenous protoplanetary nebula or from a liquid magma.
Since the moon is believed to have formed by a giant impact of a roughly mars-sized body with the proto-Earth millions of years after most meteorites were formed and moon experienced ongoing magmatic activity thereafter, the ages obtained by radiometric dating of moon rocks are usually younger than those of meteorites.

What dont the moon have for the meteors to burn up in?
THe Moon doesn't have an atmosphere, which is what protects Earth from most meteorites.
Many more meteorites reach the surface of the moon because?
They're trajectory brings them too close to the moon, and its gravitational pull gets ahold of them.
How old were the lunar rocks Apollo brought back?
As old as the moon, or younger. Probably most were remnants of asteroids or pieces of moon that were blown off when an asteroid collided with it. Scientifically? 4.6 billion years old.
Which country has the most meteorites?
Oman has 2.412 meteorites.
How does the moon get smooth?
Most of the surface of the Moon isn't smooth at all, because of the rocks, hard soil, and many craters that dot the surface.

What are the holes in the moon and how were they made?
The "holes" in the Moon are craters; it's likely that most of those are caused by meteorites.
-More meteorites reach the surface of the moon than the Earth Why?
Most of the meteorites which reach Earth burn up as they enter Earth's atmosphere due the heat caused by friction. The moon has no atmosphere.
Is some of the most extreme tornado's on the moon?
No. The moon has no atmosphere so it can't have tornadoes. But Meteorites can hit the moon. That is why it has so many craters.

Do more meteorites fall in antarctica?
No. Meteorites fall at the same rate over all places on Earth. However, meteorites are easier to find in Antarctica as they are easy to spot on top of the ice sheet. In most other places meteorites don't stand out much and are easily mistaken for ordinary rocks.
Is most of the moon surface covered by rocks?
Most of the moon is covered by a powder that is rather sticky
Why are there rocks on the moon that are older that any rocks on earth?
There is no geologic activity or weathering on the moon to break rocks down, so most of the rocks on the moon are nearly as old as the moon itself. Earth is geologically active and has processes that will destroy and recycle rocks. None of the rocks that made up Earth's original surface are still intact.
Which country has the most meteorites?
Oman has 2.412 meteorites.
Why are there thousands of craters on the moon?
The moon doesn't have an atmosphere, so meteorites hit the surface and create the craters. Earth's atmosphere causes most meteorites to burn up due to air friction before the meteorite can crash on to the surface. A 'shooting-star' is a meteorite burning up in the sky.
