Here is a great shot of the earth from the surface of the moon.  This will show you exactly.  

Definitively not the wall.  

Answer 3

The great wall of china is not even visible from 400 km away, and the moon is 400,000 km away.

Deserts and continents can be seen, also the oceans.  

Answer 4

Great Wall of China

Answer 5

Deserts.

The great wall of china is about the width of an average suburban road... which can not be seen from space.

A desert on the other hand can be several thousand kilometres wide and is a definite red/yellow colour. Definately observable.

Answer 6

As majestic as the great wall is, you cannot see it from space because it is too thin (analogous to seeing a strand of hair from far away)

Desert it is

Answer 7

Deserts!

Answer 8

With no telescope you can see clearly whole continents and clouds. Probably the sahara desert would stand out. The great wall cannot be seen. The Earth would appear about 3 times bigger in the sky as seen from the Moon than the Moon does in Earth's sky. That isn't that big.

Answer 9

a shot taken from Apollo 17

the great lakes are visable from space but not sure how far away
