An astronaut is able to float slightly on the moon due to the gravity, the gravity being 1.62 m/s² which would be lighter then the earth's which is 9.78 m/s².
Very acuratley, once the rate of birth, mortality rate, and infant mortality rate are taken into perspective.
Explanation:
as the ocean plate is pushed under the overriding continental plate the ocean sedimentary layers are heated compressed and melted the pressure of the converging plates that create the subduction zone forces the Continental play upwards creating mountain ranges such as Andes
The African countries can easily be described and generalized, in the sense of the whole continent, as the economies are predominantly dependent on one or two products.
That dependence on one or two products is making very big problems, and it is also a very big mistake of the governments. When there's a slight variation in the prices on the certain product, the economies are heavily influenced, often in a bed manner.
It is weird though that the African countries have orientated their economies in this way, especially because the continent is very rich in lots of natural resources.
The answer is D. The question asks how different cultures influenced each other so that rules out options A & B. Option C is about the environment being destroyed, and that really has nothing to do with foreign influence.
