Longitude and Latitude angle at 12M

In summary, the conversation discusses the angle that is made at longitude = 0 and latitude = 0 at midnight, as well as the location of longitude = 0 in Greenwich, England. The point of longitude = 0, latitude = 0 is in the Atlantic Ocean near Ghana and Gabon. It is important to clarify that "12M" refers to midnight and not an altitude measurement.

At longitude = 0 and latitude = 0 what angle does it make at midnight? And where is long=0 located, Greenwich, England?

This sounds like homework.

1] What angle do you think it is?
2] What does midnight have to do with anything?
3] Correct.

What does it refer to?

The "longitude= 0" meridian passes through Greenwich, England (which is part of London). "Latitude= 0" is, of course the equator.

The point of "long= 0, lat= 0" is in the Atlantic Ocean, about 380 miles (611 kilometers) south of Ghana and 670 miles (1078 km) west of Gabon.

Also, if it is homework, make sure that "12M" is referring to midnight, and not an altitude (12 Meters or 12 miles).
 

1. What is the significance of the longitude and latitude angle at 12M?

The longitude and latitude angle at 12M is significant because it represents the exact location on the Earth's surface where the sun is directly overhead at noon. This is known as the solar noon and can be used to determine the time and location on Earth.

2. How is the longitude and latitude angle at 12M measured?

The longitude and latitude angle at 12M is measured using a device called a sextant. This instrument measures the angle between the horizon and a celestial body, such as the sun, at the exact moment of solar noon at a specific location.

3. What is the difference between longitude and latitude angle at 12M and the standard longitude and latitude lines?

The standard longitude and latitude lines represent the coordinates of a specific location on Earth's surface, while the longitude and latitude angle at 12M represents the angle at which the sun is directly overhead at that location. This angle is not constant and changes throughout the year due to the Earth's tilt and orbit around the sun.

4. How does the longitude and latitude angle at 12M affect the length of a day?

The longitude and latitude angle at 12M can affect the length of a day because it determines the time of solar noon, which can vary depending on the location. As the Earth rotates, the longitude and latitude angle at 12M changes, which can affect the duration of daylight hours at a specific location.

5. What other factors can affect the longitude and latitude angle at 12M?

The longitude and latitude angle at 12M can be affected by factors such as the Earth's tilt, the location's distance from the equator, and the time of year. These factors can cause the angle to vary and can also affect the duration of daylight hours at a specific location.
