The lines running North to South are called “Meridians” or “lines of longitude” (Figure 2), while the lines running East to West are called “Parallels” or “lines of latitude” (Figure 3). Figure 2. Meridians or “Lines of Longitude” and degree readings for longitudes in increments of 30 degrees.
Why are longitudes called parallels?
Circles of latitude are often called parallels because they are parallel to each other ; that is, planes that contain any of these circles never intersect each other. A location's position along a circle of latitude is given by its longitude. ... A circle of latitude is perpendicular to all meridians.
Why is longitude not parallel?
The lines of longitudes are not parallel to each other because they come closer to each other as they approach the North and the South pole . At the poles, the meridians of longitudes meet each other.
What are Latitudes also known as?
Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels .
Where is the distance between meridians the largest?
The maximum distance between any two meridians is at the Equator . The distance between any two meridians decreases as we move away from the Equator. Meridians cut the parallels at night angles (90o). Meridians are used to measure distances in the east- west direction.
What is another name of longitude?
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 .
What are latitudes Class 6?
Latitudes are imaginary lines that run from west to east , ranging from zero to 90 degrees. Another imaginary line on the globe that divides it into two equal parts at zero degree latitude is called the equator. The equator divides the earth into the Northern Hemisphere and the Southern Hemisphere.
How many latitudes are there in total?
Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers).
What are called parallels?
Circles of latitude are often called parallels because they are parallel to each other; that is, planes that contain any of these circles never intersect each other. ... The latitude of the circle is approximately the angle between the Equator and the circle, with the angle's vertex at Earth's centre.
What are the 2 main lines of longitude?
1. Prime Meridian = Longitude 0 o (Greenwich Meridian). 2. International Date Line (Longitude 180 o ) .
What are the 12 meridians?
- Lung Meridian. The lung meridian controls how energy is consumed and impacts the respiratory system.
- Large Intestine Meridian. ...
- Stomach Meridian. ...
- Heart Meridian. ...
- Small Intestine Meridian. ...
- Bladder Meridian. ...
- Kidney Meridian. ...
- Pericardium Meridian.
What is called distance between two longitudes?
The distance between longitudes at the equator is the same as latitude , roughly 69 miles.
What is 0 longitude called?
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere.
What do we call each half of Earth?
Powered by. Any circle drawn around the Earth divides it into two equal halves called hemispheres . There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. ... The Earth can also be divided into hemispheres along meridians, or lines of longitude.
Why there are 180 latitudes and 360 longitudes?
Longitude lines runs from North to south pole means a complete circles and hence covers 360 degrees and that is why there are 360 longitudes. ... Each section from equator to pole is 90 degrees and two poles have 2 quarters of circle/globe hence 90X2 180 lattitudes. adding the Equator it becomes 181 latitudes.
What is an axis Class 6?
Axis: The imaginary line around which the earth rotates
