Answer:
Colonialism, that is, the policies carried out by the European powers to obtain territories abroad and exploit them economically within the framework of mercantilist economic production, forever marked the destiny of the different nations that emerged from the colonized territories.
This was the case, among others, of the nations of Central America and the Caribbean, where powers such as Spain, England, France, the Netherlands and Portugal established different colonies, transferring their cultures to these territories, to the detriment of native cultures, which they were displaced and in many cases wiped out by the colonizers.
In this way, the nations of these regions are the product of said colonialist intervention: their peoples emerge from the mixture of Europeans, slaves, natives and later migrants, and their cultures are also a mixture between these nations. In addition, politically these countries have adopted Western systems, leaving aside the systems applied by the natives.

Glacial evidence in african continent and in indian subcontinent , which is very warm region now are the evidence of continental drift .
Scientists Have Found Hidden Evidence of Ancient Ice Streams in The African Desert. Once, about 300 million years ago, when southern Africa was joined at South America's hip, this now arid region was covered in a wide expanse of glaciers.
- here Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.
- In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface.
- The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

Answer:
Yes, The oceanic crust is more dense but thinner than the continental crust,
Explanation:
- As the continental crust is 35-40 km, more thicker than that of the oceanic crust and it accounts for a mean surface elevation of three miles. Hence the continental crust is lighter than the oceanic crust and thus the less dense crust floats or stays at the top but the thickness of the oceanic crust is 7 to 10 km.
- <u>As the surface crust is a layer of the granitic and the sedimentary and metamorphic rocks and about 40% of the earth's surface is formed by this plate or continental crust and rest 60% is by the oceanic crust which is made of basalt. Both are less dense than the mantel.</u>
