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.

I hope that you are able to see the difference, and I hope this helped you, if you need any more help, contact me!
The statement "the extreme pressure and freezing temperatures of the deep ocean make it dangerous to send humans to the greatest ocean depths" best explains why scientists depend on submersibles to study ocean features .
<u>EXPLANATION:</u>
The oceans are so vast and deep that humans cannot withstand the pressure in depths.
Submersibles are developed in such a manner that they can travel to the deepest parts of the ocean and study ocean life.
Submersibles are vehicles that have the capability to carry humans as well to the deep ocean floors or these can be controlled in an automatic manner.
The submersibles are provided with tools and technologies that can record ocean floor features and make their study possible.
