Q. No. 1
Q. No. 2 Why is
it 5:30 pm in India when it is 12 pm or noon in London?
Ans. The time difference between India and
London is 5 hours and 30 minutes because they are in different time zones.
India follows Indian Standard Time (IST), which is 5 hours and 30 minutes ahead
of Greenwich Mean Time (GMT), the standard time in London. When it is 12 pm or
noon in London, it is 5:30 pm in India.
Q. No. 3
Why do we need
symbols and colours in the map?
Ans. Maps use symbols and colours to
represent different features, which makes them easier to understand. Symbols
help to include a lot of detail in the limited space on a map. For example, a
small picture of a train station can represent an actual train station. Colours
can be used to represent features such as water bodies or elevation changes.
Q. No. 4
Find out what
you have in the eight directions from your home or school.
Ans. This question asks what is located in
the eight directions from your home or school. Find it with Friends.
Q. No. 5
What is the
difference between local time and standard time? Discuss it in groups, with
each group writing an answer in 100 to 150 words. Compare the answers.
Ans. Local time is the specific time
for a particular location, which is determined by its longitude. Standard
time is a uniform time adopted by a country or region, usually based on a
specific meridian passing through it. While many places within a country might
have different local times, the entire country follows the same standard time.
In India, for example, the entire country follows IST, even though different
locations within India have different local times.
Q. No. 6
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?
Ans. Although Delhi and Bengaluru have
different latitudes (29°N and 13°N), their longitudes are almost the same
(77°E). Since longitude determines local time, the difference in local time
between Delhi and Bengaluru would be negligible.
Q. No. 7
Mark the
following statements as true or false; explain your answers with a sentence or
two.
Ø All parallels of latitude have the same
length.
Ø The length of a meridian of longitude
is half of that of the Equator.
Ø The South Pole has a latitude of 90°S.
Ø In Assam, the local time and the IST
are identical.
Ø Lines separating the time zones are
identical with meridians of longitude.
Ø The Equator is also a parallel of
latitude
Ans. Here are the answers, marked as true
or false, with explanations:
- False. All parallels of latitude do not
have the same length. The Equator is the longest parallel, and the circles
get smaller as you move towards the poles. - True. A meridian of longitude runs from
one pole to the other, forming a half-circle. The Equator is a full circle
around the Earth, so a meridian’s length is half of the Equator’s length. - True. The South Pole is located at 90°
South latitude. - False. While India follows a single
standard time (IST), Assam would have a different local time due to its
longitudinal position within India. - False. Time zone lines are not always
identical to meridians of longitude. They are adjusted to follow
international borders and political considerations. - True. The Equator is a parallel of
latitude, specifically the one marking 0° latitude.
Q. No. 8
Solve the
crossword below.
Ans.
Across
- SCALE – A map scale allows you to
represent a large area on a smaller surface, like a sheet of paper. - GLOBE – A globe is a spherical
representation of the Earth. - EQUATOR – The Equator is the longest
parallel of latitude, circling the Earth at 0° latitude. - GREENWICH – The Prime Meridian, designated
at 0° longitude, passes through Greenwich, England. - MAP – Maps are diagrams used to
represent geographical areas and features. - LATITUDE – Latitude measures the distance
north or south of the Equator.
Down
- LONGITUDE – Longitude measures the distance
east or west of the Prime Meridian. - COORDINATES – Latitude and longitude are
coordinates used together to define any location on Earth. - GRID – Latitudes and longitudes
together form a grid system on the globe, allowing for precise location
identification. - IST – IST stands for Indian Standard
Time, the standard time observed throughout India. - POLES – The North and South Poles are
located at the extreme ends of the Earth’s axis of rotation. - DATELINE – The International Date Line,
located around 180° longitude, marks the transition point for changing
dates when travelling east or west.
