To survive, otters need clean water in a relatively special, undisturbed environment.
That, and their small numbers over a large area, made them very vulnerable to pollution, habitat destruction and historic unregulated fishing. Unlike most people, sea otters like to cool their feet. In fact, their ice consumption is so high that Den Blå Planet has decorated the otter's enclosure with its own ice machine, so they always have a cold treat close at hand.
From the Vancouver Aquarium: Sea otters usually catch hard-shelled food - clams, abalone, clams, crabs... If they are too hard to break with their teeth, they crush them with a rock or against a rock. This is what this sea otter (Elfin) does when it hits the ice on a rock.

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.
Based on the Continental drift hypothesis, it is believed that<u> B. </u><u>Continents </u><u>may </u><u>collide </u><u>in the </u><u>future</u><u>.</u>
<h3>Continental Drift Hypothesis</h3>
- Posits that continents were once part of a super continent and then broke apart.
- Posits that continents will keep moving until they collide again to form another super continent after which they will then break apart.
The hypothesis therefore posits that continents will collide at some point millions of years into the future with one such example being the Americas and Asia.

Answer:
It is difficult to cross.
Explanation:
The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.
As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.
Farming is a common economic activity around two important rivers in South Asia, the INDUS and the GANGES
Explanation:
Ganges and Indus are two of the major rivers flowing in South Asia. They came into existence a long time ago. These rivers along with the Brahmaputra are known to be the backbone of South Asia in terms of culture and economy. The three rivers have contributed to the rise of the earliest civilizations in history.
Farming is the major economic activity in which these rivers have contributed and still contributing to the present as the soil present around them is very fertile and is ideal for various crops such as Wheat, Rice,Cotton,Sugarcane and Maize. The fertility of the soil is replenished when the rivers are flooded making it ready for next cultivation.
