How do you find equatorial circumference

Example 1: If the diameter of the planet Mercury is 3, miles, what is the circumference of Mercury? Example 2: It is given that the diameter of the sun is , miles, find the circumference of the sun. Circumference is defined as the length of the boundary of a circle. It can also be described as the arc length around a circle. Radius is defined as the distance between the center of the circle to the circumference of the circle.

Diameter is the line segment that passes through the center of a circle, and two of its endpoints lie on the circumference of the circle. The circumference of the Earth is the distance measured around it.

The circumference of the Earth measured around the Equator is approximtely 24, By knowing the Equatorial diameter or the polar diameter of the Earth, the circumference can be found.

T he circumference of the Earth around the equator is approximately 24, miles. As the shape of the earth is an oblate spheroid, the diameter is different at the equator and at the poles. Since the diameter at the equator is greater than the diameter at the poles, hence, the circumference of the great circle at the equator is the greatest.

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. 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. Sea level is determined by measurements taken over a year cycle.

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.

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.
