Answer:
C. Brazil
Explanation:
The South American country that managed to achieve independence is actually the largest and most populous country, Brazil. Brazil has been established as a Portuguese colony during the Age of Exploration.
The Portuguese saw what is now Brazil as an excellent territory for making a colony where large plantations of cash crops will be established, thus to make lot of wealth from them. That functioned well for some time, but the authorities in Brazil gradually started to become more and more powerful.
With the colony slowly becoming more and more independent, and the population growing rapidly and surpassing the one of Portugal, Brazil decided that it wanted to be independent. While the Portuguese were not fond of this idea, they saw that it would be impossible for them to win a war with Brazil at that time, so the independence was gained through negotiations.
Portugal and Brazil kept close thighs and good relations, and still do.
Answer:
Heat from the mantle forms convection currents causing the tectonic plates to diverge and form ocean basins.
Explanation:
Ocean basins form as a result of convection in the mantle along divergent margins.
- At a divergent margin, new crusts are being formed.
- It is said to be a constructive margin because new materials reaches through to the earth surface from there.
- The mantle convection pushes materials up and down away from heating centers and to cold regions and back and forth.
- This leads to the creation of cells which moves the overlying plate.
- The mantle materials are then able to reach the surface to form new ocean basin.
