Question

Долготу каких двух точек Земли нельзя определить? Почему?

Answer 1

это Северный и Южный полюсы.

они не имеют никакой долготы и мы с полным правом можем написать любое число.

 

Answer 2

The Inability to Determine the Longitude of Two Points on Earth

The longitude of two points on Earth cannot be determined precisely due to several reasons. One of the main reasons is the lack of a universally agreed-upon reference point for measuring longitude. While latitude is measured from the equator, there is no equivalent fixed reference point for longitude. The prime meridian, which passes through Greenwich, London, is commonly used as a reference point, but it is a human-made convention and not an inherent feature of the Earth's geography.

Another reason is the irregular shape of the Earth. The Earth is not a perfect sphere but rather an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. This irregular shape makes it challenging to define a consistent and accurate system for measuring longitude.

Additionally, the Earth's rotation is not perfectly regular. It experiences variations in its rotation speed due to factors such as tidal forces, atmospheric conditions, and geological events. These variations, known as irregularities in the Earth's rotation, can affect the accuracy of longitude measurements.

Furthermore, the measurement of longitude requires precise timekeeping. The Earth rotates 360 degrees in approximately 24 hours, which means that each degree of longitude corresponds to about four minutes of time. To determine the longitude accurately, one needs to know the exact time at both the reference point and the point of interest. However, maintaining synchronized time across different locations can be challenging due to factors such as time zone differences and the need for accurate and reliable timekeeping devices.

In summary, the inability to determine the longitude of two points on Earth precisely is due to the lack of a universally agreed-upon reference point, the irregular shape of the Earth, variations in its rotation speed, and the need for precise timekeeping.
