The total number of parallels across the globe is
If parallels of latitude are drawn at an interval of one degree, there will be 89 parallels in the northern and the southern hemispheres each.
So the total number of parallels thus drawn, including the equator, will be 179.
The total number of meridians across the globe is
The western most longitude is 180W and the eastern most longitude is 180E; incidentally, 180W and 180E are the same longitude. This is called the 180th meridian and also the international date line. Therefore, the total number of latitudes are 181; and the total number of longitudes are 360.
Northern half of the earth is known as the _____ and the southern half is known as the
The equator is an imaginary circle that divides Earth into two halves. The northern half is called the Northern Hemisphere. The southern half is called the Southern Hemisphere. The northernmost point on Earth is called the North Pole. The southernmost point on Earth is called the South Pole.
The Standard Meridian of India is
The standard meridian of India is the 82.5º east longitude which passes through Allahabad. This is five and a half hours ahead of 0º meridian (Greenwich).
The frigid zone lies near
The Frigid Zone lies near the Poles. The climate in the Polar Regions is very cold that is why the area is known as the Frigid Zone. It includes the area around the North Pole and the South Pole.
The Prime Meridian passes through
The International Meridian Conference took place in October 1884 in Washington DC. Twenty-five nations were represented at the conference by 41 delegates. The Greenwich Meridian was chosen to become the Prime Meridian of the World. There were several reasons for this; the main one being that nearly two thirds of the World's ships were already using charts based on it.
The voting was 22:1 in favour of Greenwich (San Domingo, now the Dominican Republic, voted against); France and Brazil abstained. The French did not adopt the Greenwich meridian until 1911.
What is a globe?
The word globe comes from the Latin word globus which means round mass or sphere. A terrestrial globe is a three dimensional scaled model of Earth. The fact that earth resembles a sphere was established by Greek astronomy in the third century BC and the earliest globes came from that period. Unlike maps, the globe is a representation which is free from distortions (distortion in shape, area).
What are meridian of longitude?
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. The distance around the Earth measures 360º.
Why does the Torrid Zone receive maximum amount of heat?
The area between the Tropic of Cancer and the Tropic of Capricorn is known as the Torrid Zone. The mid-day Sun is exactly overhead at least once a year on all the latitudes in this area; hence, this area receives maximum amount of heat.
The value of the prime meridian is
A prime meridian is a meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°.
