What is the significance of equator

The equatorial bulge means that people standing at sea level near the poles are closer to the center of the Earth than people standing at sea level near the Equator.

The equatorial bulge affects the ocean, too—sea levels are slightly higher in equatorial regions than near the poles. The equatorial bulge is created by the Earth's rotation. As lines of latitude increase in size, a point has to travel faster to complete a circle revolution in the same amount of time. The rotational speed, or spin, at the Arctic Circle is slower than the spin at the Tropic of Cancer, because the circumference of the Arctic Circle is much smaller and a point doesn't have to travel as far to complete a revolution.

The spin at the Tropic of Cancer is much slower than the spin at the Equator. Near the poles, the Earth's rotational speed, or spin, is near zero. At the Equator, the spin is about 1, kilometers per hour 1, miles per hour. The Earth's gravitational pull is slightly weaker at the Equator due to its equatorial bulge. The slightly weaker gravitational pull and momentum of the spinning Earth makes equatorial regions ideal places for space launches.

It takes an enormous amount of energy to launch a satellite or other spacecraft out of the Earth's atmosphere. It takes less energy rocket fuel to launch in lower gravity. It also takes less energy to launch when the spinning Earth is already giving the satellite a push of 1, kilometers per hour 1, miles per hour. The United States launches most spacecraft from the Kennedy Space Center in southern Florida, as close to the Equator as possible in the continental U. Recently, mobile launch platforms, such as Ocean Odyssey , have successfully launched satellites into orbit from the equatorial Pacific Ocean.

Equatorial Climates Twice a year, during the spring and autumn equinox es, the sun passes directly over the Equator. Even during the rest of the year, equatorial regions often experience a hot climate with little seasonal variation. As a result, many equatorial culture s recognize two season s—wet and dry. The wet, or rainy, season often lasts most of the year. The long, warm, rainy season creates tropical rain forests.

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. A single hectare 2. The equatorial savanna of Kenya includes mammals such as lions, cheetahs, and elephants. What Is the Importance of the Equator? More From Reference.
