3. Ans. (d) 1, 2, 3, 4 and 5

Explanation: Factors influencing the temperature of a place are

• Latitude: As the Earth’s crust is curved, the vertical ray of the Sun falls on the earth's surface at different angles. At the equator, the vertical rays directly hit the Earth and become slant as we approach poles.

• Altitude: As we go up, air pressure decreases and so does the temperature. We find snowfall at higher altitudes.

• Distance from the sea: The difference in heating of ocean and land affects the temperature of places located near the coast from those located on the mainland continent.

• Air Mass Circulation: Warm and cold air mass affects the temperature and precipitation of a place.

• Presence of warm and cold ocean currents: Ocean currents (warm and cold) are large streams of water flowing in oceans. These not only affect the temperature of a particular place but also rainfall.

4. Ans: (d) 1, 2 and 3

Explanation:

• Carbon dioxide and water vapour are found up to 90 km from the surface of the earth.

• The troposphere is the lowermost layer of the atmosphere. Its average height is 13 km and extends up to a height of 8 km near poles and about 18 km at the equator. After the troposphere, the stratosphere extends up to 50 km. So, Carbon dioxide and water vapour are found in the Stratosphere also.

• Ozone is an important part of the atmosphere found between 10 and 50 km above the earth’s surface and acts as a filter and absorbs the ultraviolet rays radiating from the sun. So, it is found in both the troposphere and stratosphere as the height of the troposphere extends up to 18 km.

5. Ans: (c) 3 only

Explanation:

• Most inscriptions have been found on seals and they contain only a few words. Most of them are pictorial forms as evident from the figure.

• These seals may have been used by the proprietors to mark and identify their private property.

• The Harappans domesticated oxen, dogs, buffaloes, goats, pigs but not horses.
