Some of the most expansive rain forest s in the world are in equatorial regions: the Amazon rain forest of South America, the Congo rain forest of Central Africa, and the varied Southeast Asian rainforest stretching from India to Vietnam. Humid weather means that equatorial regions are not the hottest in the world, even though they are among the closest to the sun.
The water in the equatorial air cools it slightly. Many cultures thrive in warm equatorial regions. The Fang people of Gabon, for instance, are successful farmers who take advantage of the warm temperature and long rainy season to cultivate crop s such as corn, yams, and plantains.
The Fang also raise livestock that have adapted to the climate, such as goats and chickens. Not all equatorial regions are hot and humid, however. Mount Kilimanjaro, Tanzania, is only kilometers miles from the Equator, but its elevation creates a climate with cool, dry weather and even alpine glacier s.

The Andes are another equatorial region lacking the hot, humid climate often associated with the Equator. The mountain range includes a desert with almost no rain the Atacama , as well as some of the tallest peaks on Earth. Here, too, cultures have thrived for thousands of years.
The Aymara people of the Altiplano of Bolivia, Peru, and Chile, are primarily an urban people who identify strongly with the innovative navigation al successes of their ancestors. In the 20th century, the Aymara helped build railroads through the high, equatorial Andes. Many plant and animal species thrive in equatorial climates. The Amazon and Congo rain forest ecosystem s, for example, are amazingly rich in biodiversity.

The chilly equatorial Andes are famous for its camelid species: llamas, alpacas, vicunas, and guanacos. Earth's equatorial bulge pushes Mount Chimborazo, near the Equator in the Ecuadorian Andes, further from the center of the Earth.

However, elevation is measured from sea level, not the center of the Earth. Mount Everest is 8, meters 29, feet above sea level, while Mount Chimborazo is just 6, meters 20, feet above sea level. Crossing the Line Sailors have elaborate rituals and celebrations when they cross the Equator, which they call crossing the line. Sailors who have never crossed the line are called pollywogs.
Pollywogs are usually the target of embarrassing practical jokes. Short Sunsets The time it takes for the sun to set and rise at the Equator is the fastest on Earth. The transition from day to night takes only a few minutes. Regions are the basic units of geography.

The northern hemisphere experiences summer during the months of June, July, and August because it is tilted toward the sun and receives the most direct sunlight. Inversely, summer for the southern hemisphere takes place during the months of December, January, and February because that is when it receives the most direct sunlight.

All places on earth have their own climates. Different from weather events, which are short-term and temporary phenomenon, climates are usually steady and predictable, and shape how organisms and human civilizations evolve and adapt in any given region. However, climates are not always permanent, and can change drastically due to human activity.
Explore the world's climates and how they affect local regions and the planet with this curated collection of resources. Most of it was written in snatches while waiting to be dragged about, often against our will, by the tour guides that we foolishly and ignorantly had prepaid for services we didn't want. I have attempted to smooth the flow in places but in others I find the almost telegraphic style captures the flavor of the trip.
If you find it amusing or at all informative then I shall not have preserved it vain. On entering the Buenos Aires International airport a helpful young man directed us into the queue for returning citizens and the inspector was outraged when we handed him U. The mass of nonresidents was seething within the twisted confines of the labyrinthine ropes so we fell onto the end of one of two parallel queues. People were constantly switching from one to the other, which of course is typical of grocery store checkout lines as people try to guess who ahead of them has cash and who has coupons, so we paid no attention to that, but as the fog of twenty-two hours of sleeplessness ebbed and flowed I attempted to follow the switchbacks to see where our line would terminate.
There were two destinations: immigration kiosks and cashiers. You see, Argentina has what they call a reciprocity tax. They charge citizens of the U.

They hasten to explain that it is not a visa—simply revenge. Still it looks and acts like a visa. Whether or not it is a visa, it would be much more convenient to pay the fee and get a visa before leaving home because after many minutes I realized our line was not destined to end at the cashiers. So, now at the end of the third queue, we questioned whether our greeter would wait for us as the plane had arrived half an hour late and it was ultimately over an hour before we cleared immigration. The next hurdle was baggage that had been languishing on the carrousels for so long. There were a lot of carrousels, and the monitors at their return loops were more likely to be selling excursions to the playa then identifying from which flight the luggage had come.
With luck we found our bags apparently unmolested and proceeded through the enormous duty free store bumping into displays that we mistook for the exit. Hundreds of greeters with names scrawled on sheets of paper made an arena for the arriving passengers giving one to feel like cattle at auction. When we meekly pointed to it people called to a big friendly fellow who introduced himself as Julio and shook our hands. He examined our new rolling bags and went to find a luggage cart.
Now, this is why I prefer not to travel with tour companies. The right way to arrive abroad is to have the first hotel reserved, go to the curb and hail a cab. The U.
Predictably our room was not ready. To pass the time we sat on a bench in the parkway of the boulevard next to the recumbent form of an AIDS sufferer. I know this only because he carried a sign soliciting handouts on account of his affliction. Sandy couldn't read it, of course, and she said she would have rather I hadn't translated it for her. Twice we returned to be told the room was still not ready. We tried to wait in the lobby where I hoped we could doze in the club chairs, but the place was being remodeled and resonated with hammering and grinding.
