Define -
a) Equator
b) Prime Meridian
2. Draw a diagram to show lines of longitude.
3. Name five important lines of latitude with their latitudinal value.
4. Write four differences between the lines of latitude and lines of longitude.
5. Draw a diagram to show the three heat zones (climatic zones)
6. Describe the heat zone which receives the maximum heat.
7. In Frigid zones sun does not rise much above the horizon. Sun rays are always slanting.
What would be the climatic conditions there?
8. Places to which side of International date line will be ahead in time – East or West?
9. If it is 12:00 Noon at a place on Prime Meridian (0° longitude), find out the time of a place
on –
a) 20° E longitude
b) 20° W longitude
c) 15° E longitude
d) 30° W longitude
e) 82.5° E longitude
Rules –
➢ Time of a place depends upon its meridian.
➢ Places to the East are ahead in time (difference would be added).
➢ Places to the West are behind in time (difference would be subtracted).
➢ Time taken to turn distance of

Answer:
A prime meridian is the meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid into two hemispheres. If one uses directions of East and West from a defined prime meridian, then they can be called the Eastern Hemisphere and the Western Hemisphere.
The equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is the imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles.
The five major lines of latitude, more commonly referred to as the five major circles of latitude, mark specific points on a globe or map of Earth. Four of the lines run parallel to the equator and sit north or south above or below the equator. Visible on a globe or map of the Earth, points on latitudes that cross over longitude lines mark specific locations on the Earth.The Arctic Circle is located at approximately 66.5 degrees north latitude, or 66.5 degrees north of the equator. This circle of latitude stretches through eight countries, including the United States, Canada, Greenland, Iceland, Norway, Sweden, Finland and Russia. The Arctic Circle marks the beginning area where the sun will not rise during winter solstice and will not set during summer solstice.The Antarctic Circle is located at approximately 66.5 degrees south latitude, or 66.5 degrees south of the equator. This line, or circle, of latitude marks the start of the southern area known as the Antarctic. The circle consists of only one continent, Antarctica. There are not any humans within the boundaries of the Antarctic Circle that can be considered permanent residents of the area.Possibly the most well-known circle of latitude is the line sitting at zero degrees latitude, the equator. The equator circles the globe with a circumference of nearly 25,000 miles, dividing the northern and the southern hemispheres. This line of latitude is the starting point when referring to other points of the globe in terms of degrees north and degrees south.The Tropic of Cancer is located at approximately 23.5 degrees north latitude, or 23.5 degrees north of the Equator. This line of latitude is the northern boundary of the area referred to as the tropics. During the summer solstice the sun is located immediately above the Tropic of Cancer. This line is the point farthest to the north at which the sun is hanging directly upward at noon.The Tropic of Capricorn is located at approximately 23.5 degrees south latitude, or 23.5 degrees south of the equator. This line of latitude is the southern boundary of the area referred to as the tropics. This line marks the point farthest to the south at which the sun is hanging directly upward at noon. During the summer solstice of the Southern Hemisphere, the sun is located immediately above the Tropic of Capricorn.
Latitudes Longitudes
1 They run from West to East They run from North to South
2 Lines are parallel to each other Lines are not parallel to each other but converge at the poles
3 The lines are not of same length Lines are of the same length
4 The equator is the only great circle Has many great circles as any opposite pairs of lines make a great circle

6 Lines are used for measuring distance Lines are used for measuring local time
