Question

Place	Country	Mean Max. Temp. °C	Mean Min. Temp. °C	Range of Temperature
Beijing	China	18.4	08.4
Istanbul	Turkey	18.0	10.0
Madrid	Spain	19.0	09.0
New York	United States	16.3	08.3
Denver	United States	16.2	02.2
Kabul	Afghanistan	14.7	05.2
Baghdad	Iraq	30.4	14.7

The above table records the maximum and minimum temperatures from some places located between 30∘ and 40∘ north parallels. Study the table and do as directed.

• Calculate the difference between the mean maximum and minimum temperatures and write it in the last column.
• Highlight the rows for the places having a range of temperature over 10°C with red colour.
• Colour other rows in blue.
• Find the locations of these places from an atlas.
• Which places are closer to the oceans? Tell whether the range of temperature at these places is less or more.
• What might be the main reason leading to differences in the temperature range of different places?
• In which thermal zone are all these places located?
• Which places are far away from the oceans? Do those places have a greater or smaller temperature range?
• Mention the places having the smallest and greatest temperature ranges.
• Draw a graph for the above data. Use a proper colour scheme.

Answer 1

Place	Country	Mean Max. Temp. °C	Mean Min. Temp. °C	Range of Temperature
🔵Beijing	China	18.4	8.4	10.0°C
🔵Istanbul	Turkey	18.0	10.0	8.0°C
🔵Madrid	Spain	19.0	9.0	10.0°C
🔵New York	United States	16.3	8.3	8.0°C
🔴Denver	United States	16.2	2.2	14.0°C
🔵Kabul	Afghanistan	14.7	5.2	9.5°C
🔴Baghdad	Iraq	30.4	14.7	15.7°C

🔴 Range over 10°C
🔵 Range 10°C or less

• Beijing, Istanbul, Madrid, New York and Kabul should be coloured blue.
• Locations of these places from an atlas
  1. Beijing – China
  2. Istanbul – Turkey
  3. Madrid – Spain
  4. New York – United States
  5. Denver – United States
  6. Kabul – Afghanistan
  7. Baghdad – Iraq
• Istanbul, Madrid and New York are closer to seas or oceans. Their temperature range is generally smaller because the sea moderates the temperature.
• The main reason is the distance from the sea or ocean. Coastal places have a smaller temperature range, while inland places usually have a larger range.
• All these places lie between 30° N and 40° N, so they are in the North Temperate Zone.
• Denver and Kabul are far from the oceans. Such inland places generally have a greater temperature range.
• Smallest and greatest temperature ranges.
  • Smallest range: Istanbul and New York — 8°C
  • Greatest range: Baghdad — 15.7°C
