Its D. Oil is decomposed material aged over time.
The first map shows colonized nations in 1945. European powers had colonized vulnerable and faltering nations to undergird their economies. The second map shows that, even more than 50 years later, the majority of moderately developed or underdeveloped nations were former colonies of the presently highly developed nations. This conclusion supports neocolonialism in that former colonies have moved toward industrialization and economic independence. The economies of the former colonies are still, to an extent, dictated by, and even hampered by, their former colonizers.
Answer:
Continental crust is about 20 to 70 km thick and thus 70% of this submerged and oceanic crust being about 10 km thick is only 30 % submerged.
Explanation:
- As the hydrological crust is considered to be much denser than the oceanic crust hence at the subduction zones the crusts sink into the mantel and are beneath the lighter continental crust as the oceanic crust is much older than the continental crust. As the continental crust forms many layers and has a bulk composition and the average density is about 2.83 g/cm and has a thickness of about 7 to 10 km.
a. Sea-to-land breezes blow in an (On shore) direction.
b. (Convectional) currents are circular movements of rising and descending air.
c. Land-to-sea breezes (local winds) occur during (daytime).
d. During the day, air above the sea is (Cooler) than the above land.
History was a driving force behind such migration, since humans tended to move to new territory when they lacked food, shelter, or other resources--meaning that most of the conflicts throughout history have been driven by the same forces that drove migration out of Africa.
