Why are there black holes on the moon

caused by asteroids hitting it

Explanation:

I don't think it is a black hole, thinks it's called a crater/pit

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

the denominator has a very specific role.
