Answer:
Explanation:
1- Kanyakumari =8.0780° N, 77.5410° E
2- Imphal=24.8200° N, 93.9500° E
3-Jaisalmer=26.9200° N, 70.9000° E
4-Pune=18.5203° N, 73.8567° E
5-Patna=25.6000° N, 85.1000° E
a) we see Paris is in GMT +1 timezone and India is in GMT +5.5 timezone
So there will be difference of 4.5 hours when you travel from Delhi to Paris
Paris will be 4.5 hours behind IST
b) Tokyo is in GMT+9 time zone and India is in GMT +5.5 timezone So there will be difference of 3.5 hours when you travel from Delhi to Tokyo
Tokyo will be 3.5 hours ahead IST
4) It is difficult to study the structure of the Earth because the crust is too thick to drill all the way through. scientists need to study seismic waves made by earthquakes or man-made explosions
5)The earth is still active because of some nature's activities still are on run. Example volcano eruption, earthquake, land sliding, raining, rise in the level of the mountains. Explanation: The earth is the part of destruction and construction for billion of years.
6)It is an effective design which is generally to find a particular location of a place on the globe or map. A grid helps us to locate or find out the "exact location" of a place with detailed description of the latitudinal and the longitudinal extent of the place, on a globe or a flat map
7-(a)- The local time of a particular place refers to the time determined under the basis of the sun's apparent movement. On the other hand, the standard time refers to the fixed time of several places in a given region that fall under the same standard meridian
7 b)The Equator separates the Northern and Southern Hemispheres. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England and is at 0° longitude.
8)The problems are as follows1>There would have been great confusion in railways and other time -based communications are concerned. 2>Suppose you have to enter your school at 11:00 am. With your school following your own local time...the time will alter andcause great problems. 3>TV shows would hinder
9)1. 82 degrees 30 min east is the standard meridian of Nepal.
2. The standard meridian of Pakistan is UTC/GMT+05:00 hours ahead of Greenwich time.
3. The standard meridian of Bangladesh is calculated on the basis of the 90.00° E longitude which is six hours ahead of CUT.
4. The standard meridian of England is Longitude 0 degree, which passes over Greenwich.
5. The standard meridian of Malaysia is longitude 105 degree.
6. The standard meridian of Japan is longitude 135 degrees east
