Explanation:
Currents involve movement of ocean water masses, driven either by wind or by differences in temperature, salinity and density. The most important from a human perspective are the wind-driven surface currents that move water in the uppermost layer of the ocean.
Currents affect humans in several primary ways. Currents help shape the climate in the areas where we live, create the right conditions to support abundant ocean life in the areas where we fish, and change weather patterns through periodic events like El Nino/La Nina.
Ocean currents also cause upwelling in many areas like off in the inland parts of North America, where surface currents taking water away from the shore cause nutrient-rich water to well up from the ocean deeps. The abundance of nutrients in these areas forms fertile ground for kelp beds and marine fisheries, which in turn furnish food for humans. Alterations in current patterns like the El Nino/La Nina cycle affect humans as well by causing changes in local weather patterns in the years when they occur.
Hello @D1fficult,
How are you doing? As of your question, "<span>What is the main cause of the differences in the physical characteristics of the Middle East and South America?"
Well, some differences that you would see is that, first of all, the Middle East is desert. The climate is dry, almost no rain, sandstorms, and heat. In the night, its cold, more water supply, however it still is dry. Their is mountains there, and almost no animals.
South America, you may know as the Amazon Forest. The Amazon Forest is everything but the Middle East. The climate is always wet, and its always raining. Lots of Vegetation, and animal variety.
I hope that you are able to see the difference, and I hope this helped you, if you need any more help, contact me!
Thank you,
Darian D.</span>

Answer:
Greenland is the country where you most likely live in terms of its physical characteristics due to the amount of grass and nautural habitats covering the country. Greenland had a lot of maountains and natural spaces and rivers that run through it. Most of it is just green land, just like the name. Snow covered mountains, rivers, habitats, then ocean. Greenland also has a lot of different species and a diverse amount of animals which can be for hunting and gathering the food. You won't see building everywhere, you will see mostly the great nature.
