How do you measure the diameter of a pole?

Step 1 – Measure the circumference of the post (distance around the post). Step 2 – Take that measurement and divide it by pi (3.14) to determine the post diameter.

What is the diameter at the pole?

Equatorial vs Polar Diameter:



Because of this, the diameter of the Earth at the equator is about 43 kilometers (27 mi) larger than the pole-to-pole diameter. As a result, the latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi).

How do you measure a diameter?

Video quote: And I'm using a soft ended tape measure. And I look at where the end of the tape measure is meeting here and that's the diameter which is the measurement I'll use to make the cushion.

How do you measure diameter with a tape measure?

How to Use a Measuring Tape for Diameter

1. Find the center of a circular area and mark it in some way.
2. Secure a tape measure anywhere on the circle and pull the tape measure to a point on the opposite side of the circle. …
3. Measure just the radius of the circle if it is very large.

What is the diameter of the North pole?

The Earth’s diameter at the Equator is about 12,756 kilometers (7,926 miles). At the poles, the diameter is about 12,714 kilometers (7,900 miles).

What is a circle diameter?

Diameter of a circle



The diameter is the length of the line through the center that touches two points on the edge of the circle.

Are the north and South Pole the same?

The main difference is that north pole lies in the northern hemisphere, while south pole lies in the southern hemisphere. The North pole is defined as latitude 90 degrees N and the direction of true north. The South pole has latitude 90 degrees S and direction of the true south.

What is the radius of the South Pole?

Earth’s polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km). Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km).

How does South Pole look like?

At the surface at the South Pole, there is just snow and ice, there are no other natural significant features, no mountains sticking through the ice (there are hills and mountains beneath the ice, but they aren’t tall enough to reach through) no rock, no solid ground, just a vast endless plateau of more snow and more …

What is the diameter from North Pole to South Pole?

Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers). Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers).

Is there land under the South Pole?

Although land at the South Pole is only about a hundred meters above sea level, the ice sheet above it is roughly 2,700 meters (9,000 feet) thick. This elevation makes the South Pole much colder than the North Pole, which sits in the middle of the Arctic Ocean.

What is under Antarctica’s ice?

The lakes grow and shrink beneath the ice. Scientists have discovered two new lakes buried deep beneath the Antarctic Ice Sheet. These hidden gems of frigid water are part of a vast network of ever-changing lakes hidden beneath 1.2 to 2.5 miles (2 to 4 kilometers) of ice on the southernmost continent.

Has anyone been to the middle of Antarctica?

In what could go down as one of the great feats in polar history, the American Colin O’Brady, 33, covered the final 77.54 miles of the 921-mile journey across Antarctica in one final sleepless, 32-hour burst, becoming the first person ever to traverse Antarctica from coast to coast solo, unsupported and unaided by wind …

Why is Antarctica so cold?

Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn’t come up at all for months at a time.

Why do airplanes not fly over Antarctica?

What is this? The polar regions interfere with magnetic navigational equipment, making it harder for planes to navigate. It can also be difficult for planes to connect with flight controllers because of the location’s isolation.

Why is Death Valley so hot?

Why so Hot? The depth and shape of Death Valley influence its summer temperatures. The valley is a long, narrow basin 282 feet (86 m) below sea level, yet is walled by high, steep mountain ranges. The clear, dry air and sparse plant cover allow sunlight to heat the desert surface.

Who Discovered Antarctica?

The race to find Antarctica sparked competition to locate the South Pole—and stoked another rivalry. Norwegian explorer Roald Amundsen found it on December 14, 1911. Just over a month later, Robert Falcon Scott found it, too.

What will happen if all the ice in Antarctica melts?

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. But many cities, such as Denver, would survive.

What flag is Antarctica?

There is no official flag of Antarctica since it is not a country nor governed by any authority.

Who was the first woman to foot in Antarctica?

Caroline Mikkelsen

In 1935, Caroline Mikkelsen, wife of a Norwegian whaling captain, became the first known woman to set foot, briefly, in Antarctica—but not the first person. A man had stepped onto the continent more than a hundred years earlier, and men had begun the “heroic era” of Antarctic exploration decades before.

What is the population of Antarctica?

Antarctica is the world’s southernmost continent resting in the Antarctic Circle and surrounded by the Southern Ocean. With 14 million square kilometers (5.4 million square miles) of area, it’s the 5th largest continent.



So, how many people live in Antarctica today?

Do people live in Antarctica?

Antarctica is the only continent with no permanent human habitation. There are, however, permanent human settlements, where scientists and support staff live for part of the year on a rotating basis. The continent of Antarctica makes up most of the Antarctic region.

When did Germany go to Antarctica?

In August 1936, the German Foreign Office found some unclaimed territory in Antarctica between Norwegian and British zones and an expedition to explore and claim the region between 20 degrees east and 10 degrees west—part of an area known as Queen Maud Land—took shape.

Who owns the Antarctic?

Seven countries (Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom) maintain territorial claims in Antarctica, but the United States and most other countries do not recognize those claims. While the United States maintains a basis to claim territory in Antarctica, it has not made a claim.

Is there a US military base in Antarctica?

McMurdo Station is a United States Antarctic research station on the south tip of Ross Island, which is in the New Zealand–claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program, a branch of the National Science Foundation.
