What is the true shape of earth?
Most Upvoted Answer
What is the true shape of earth?
Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an oblate spheroid. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.

What is the true shape of earth?
The True Shape of Earth
The true shape of the earth is not perfectly round as believed for centuries. It is actually an oblate spheroid, which means it is slightly flattened at the poles and bulging at the equator. This shape is due to the earth's rotation causing centrifugal force, which pushes the equatorial regions outwards, while the polar regions are compressed inwards.
Measuring the Earth's Shape
The first measurements of the earth's shape were made by ancient Greeks who noticed that the earth cast a round shadow during a lunar eclipse. Later, scientists used various methods to calculate the earth's shape, including:
- Measuring the angles of triangles on the earth's surface
- Measuring the length of a degree of latitude or longitude
- Using satellites to measure the earth's gravitational field
Why is the Earth's Shape Important?
The earth's shape is important for many reasons, including:
- Navigational purposes: Accurate knowledge of the earth's shape is essential for accurate navigation by ships, planes, and other vehicles
- Geodesy: The study of the earth's shape and size is important for mapping and surveying, and for understanding the earth's gravitational field
- Understanding the earth's climate: The shape of the earth affects the distribution of solar radiation, which in turn affects the earth's climate
The Earth's Shape in the Future
The earth's shape is constantly changing due to various factors such as tides, earthquakes, and the movement of tectonic plates. However, these changes are very slow and cannot be observed easily. In the future, advances in technology may allow for even more accurate measurements of the earth's shape, which could lead to new discoveries and a better understanding of our planet.
