Discuss some of the humanitarian services that could be provided globally tovall who dont currently have those services for less than certain items that are consumed in developed regions of the world, such as the United States and Europe. What services could be provided globally? What are some examples of unnecessary items are consumed im developed regions of the world that have more spent on them that that it would cost yo provide many of those services? How do you think this reflects upon societies in developed countries? Do you think this can and should change? Why or why not?

Answers

Answer:

Hey there!

Some services that could be provided more internationally, and might be overused in developed countries such as the USA, Japan, France, and Germany, may include health care services and transportation. It would probably cost more to provide these services in remote, undeveloped places because just reaching those places costs a lot of money, and this contributes to the increasing difference between modern places and unmodernized places.

When they moved back to Spain, these countries lost the opportunity to make use of this labor and this capital. This contributed indirectly, to the slow advancement of most Latin American nations.

What happens to global winds at the Equator?

Answers

Warm air rises up at the equator and moves toward the poles. Global winds do not move directly from north to south or south to north because the Earth spins.

Answer:

A low-pressure will start forming at the surface of a region of clouds that begins at altitude. The air will eventually stop rising, and then it will begin to spread north and south to the Earth's poles.

Approximately 2000 miles from the equator, the air falls back to Earth's surface, blowing towards the pole and back to the equator.
