Class 6 Social Science Locating Places on the Earth
If you are looking for Class 6 Social Science Locating Places on the Earth , then you are at the right place.
Answer the following Questions
Why is it 5:30 pm in India when it is 12 pm or noon in London?
This is because Indian Standard Time (IST) is 5 hours and 30 minutes ahead of Greenwich Mean Time (GMT). London uses GMT (or a variation of it), so when it’s noon in London, it’s 5:30 pm in India.
Why do we need symbols and colours in the map?
Symbols and colours are used in maps to represent various features and details in a limited space. They allow maps to show numerous details that would be impossible to draw realistically given the scale of most maps. Symbols can represent different types of buildings, roads, natural features, etc., while colours can be used to distinguish between different areas or types of terrain.
What is the difference between local time and standard time?
Local time is based on the exact longitude of a specific location and changes continuously as you move east or west. Standard time is a fixed time adopted by a country or region, usually based on a specific meridian passing through that area. Standard time is used for practical purposes within a country or time zone, while local time would vary even within short distances.
Delhi’s and Bengaluru’s latitudes are 29°N and 13°N; their longitudes are almost the same, 77°E. How much will be the difference in local time between the two cities?
Since Delhi and Bengaluru are on almost the same longitude (77°E), there would be virtually no difference in their local times. The difference in latitude doesn’t affect the local time. Both cities would experience local noon at approximately the same moment, despite being at different latitudes.
State True or False.
Â
All parallels of latitude have the same length.
False. The Equator is the longest parallel of latitude, and the circles get smaller as you move towards the poles. The poles themselves are just points.
The length of a meridian of longitude is half of that of the Equator.
True. Meridians of longitude are half-circles that run from pole to pole, while the Equator is a full circle around the Earth’s circumference.
The South Pole has a latitude of 90°S.
True. The South Pole is the southernmost point on Earth, located at 90 degrees South latitude.
In Assam, the local time and the IST are identical.
False. Assam is located in the eastern part of India, so its local time would be ahead of Indian Standard Time, which is based on a meridian passing through central India.
Lines separating the time zones are identical with meridians of longitude.
False. While time zones are based on meridians of longitude, the actual boundaries often follow national or regional borders for practical reasons, resulting in irregular lines.
The Equator is also a parallel of latitude.
True. The Equator is the 0° parallel of latitude, dividing the Earth into Northern and Southern Hemispheres.
