What is the most important line of longitude?
the prime meridian Running in the opposite direction, north-south, the prime meridian is one of the most important lines of longitude on Earth.
What are the advantages from longitudes?
There are many advantages one of it is, that we can find the time and location. for example: Latitude and longitude are imaginary lines that help us label every place on the surface of the earth. The most important line of latitude is the equator, which runs horizontally around the fattest part of the earth.
Why is most important of latitude?
To avoid confusion and chaos in all activities to be caused by having a different local time for different places. The central Meridian 820 30' E is taken as the Indian Standard Time.
How does the longitude affect the time?
Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun.
What is the purpose for the lines of latitude and longitude?
The Earth is divided into degrees of longitude and latitude which helps us measure location and time using a single standard. When used together, longitude and latitude define a specific location through geographical coordinates.
What are two important longitudes?
Some Important Longitudes include: 1. Prime Meridian = Longitude 0o (Greenwich Meridian). 2. International Date Line (Longitude 180o).
How does latitude and longitude help find places on Earth?
The combination of meridians of longitude and parallels of latitude establishes a framework or grid by means of which exact positions can be determined in reference to the prime meridian and the Equator: a point described as 40° N, 30° W, for example, is located 40° of arc north of the Equator and 30° of arc west of …
What are lines of longitude and why are they important?
Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude.
Which is the most important latitude and longitude of the country give reasons?
The Tropic Of Cancer(23.5 degree North) is the most important latitude of our country because it divides our country in almost two equal parts and also effects the climate of our country.
How do longitudes help us in calculating time?
Each degree is divided into minutes and minutes into seconds. The Earth takes 24 hours to complete one rotation or to cover 360° of longitudes. This means that the Earth covers 15° of longitudes every hour. One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).

This means that the Earth covers 15° of longitudes every hour. One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).
How many important longitudes are there?
There is a total of 360 longitudes. The Prime meridian, 179 east, the longitude of 180 degrees, and also the 179 west. The western longitude is at 180W and the eastern longitude is at 180E. Both the longitudes are identical.
Why it is important to give both latitude and longitude when giving coordinate?
Why is it important to give both latitude and longitude when giving coordinates? They are used to locate places on the earth. Describe how the difference of a degree of longitude varies from the equator to the poles. Latitude is the degrees from the equator.
What are the important latitudes and longitudes?
Besides the equator (0°), the North Pole (90°N) and the South Pole (90° S), there are four important parallels of latitudes– (i) Tropic of Cancer (23½° N) in the Northern Hemisphere. (ii) Tropic of Capricorn (23½° S) in the Southern Hemisphere. (iii) Arctic Circle at 66½° north of the equator.
Which is the most important longitude and why?
The most important longitude of our country India is 82 ½ degree because it is the Indian Standard Meridian which passes through Allahabad and Chennai. It is very important because the time in India is determined ONLY by this particular meridian.
How do longitude and latitude help you locate places on earth?
Any point on earth can be located by specifying its latitude and longitude, including Washington, DC, which is pictured here. Lines of latitude and longitude form an imaginary global grid system, shown in Fig. 1.17. Any point on the globe can be located exactly by specifying its latitude and longitude.
What is the purpose of longitude and latitude?
Latitude and longitude make up the grid system that helps us identify absolute, or exact, locations on the Earth's surface. You can use latitude and longitude to identify specific locations. Latitude and longitude are also helpful in identifying landmarks.
How does longitude affect in determining date and time?
It may further be noted that the time decreases when we move from west to east and increases with our westward movement. The rate of the time at which the sun traverses over certain degrees of longitudes is used to determine the local time of an area with respect to the time at the Prime Meridian (0°Longitude).
What are the two important longitudes?
Some Important Longitudes include: 1. Prime Meridian = Longitude 0o (Greenwich Meridian). 2. International Date Line (Longitude 180o).
What longitudes are important?
The two main longitudes are the Prime Meridian and the 180° meridian. The two longitudes divide the earth into two equal halves, the Eastern Hemisphere and the Western Hemisphere.
Why is it important to use longitude and latitude in locating different countries in the world?
Latitude and longitude make up the grid system that helps us identify absolute, or exact, locations on the Earth's surface. You can use latitude and longitude to identify specific locations. Latitude and longitude are also helpful in identifying landmarks.
Why is the knowledge of latitude and longitude important?
The lines of longitude and latitude help us in measuring the distance from the Earth's Equator. Latitudes help us to find out the distance of any place from the Equator, which is base on its degree of latitude. Longitude and latitude help us to find the location of any place on earth.
How are longitudes useful in calculating time?
ANS Every gain or loss of 1° longitude stands for 4 minutes. 360° implies one complete rotation of earth. on every longitudinal degree increase towards west, substract 4 min. After the hours is calculated add(if east) or substract( if west) it with time of GMT.

Latitude and longitude make up the grid system that helps humans identify absolute, or exact, locations on the Earth's surface. There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles.
What would happen if there were no latitudes and longitudes?
Answer. if there were no latitudes and longitudes we can't find the locations of continents and places in the globe.
What is impact of longitude?
How do lines of longitude affect our daily lives? It measures how East or West a place is from the Prime Merdian. With the help of Latitude the 2 can tell us the exact location of a place. It determines the time zone a particular place is in since one Meridian passes through Greenwich in UK.
