Think a little!

Question 1.
A game of reading the meridians on the world map is going on. Shaheen and Sanket are asking each other to locate places on specific meridians and are making notes of the same. Shaheen asks Sanket to locate Wrangel Island on 180° meridians. Sanket could locate the island in the map but both are confused while making a note of it. They are puzzled whether to write 180° E or 180° W? What would be the precise answer? Please help them. Can we use a similar logic with reference to 0° meridian as well?
Answer:
The 0° and the 180° meridians lie opposite to each other and form a circle around the earth. This circle divides the earth in the eastern and western hemisphere. Shaheen and Sanket can write the Wrangled island to be loacted on 180° meridian.

Give geographical reasons for the following statements:

Question 1.
The ocean water is saltier than drinking water.
Answer:

(i) In drinking water, the proportion of salts is quite low. Water from oceans and seas has a greater amount of salt. Hence it tastes salty.

(ii) Volcanic eruptions leads to increase in the level of salts and minerals in ocean water.

(iii) Volcanic eruptions takes place in the oceans. During volcanic eruptions different minerals, ashes, salts and gases are added to the water. This increases the level of salts and minerals in ocean water.

(iv) Due to continuous evaporation of oceanic water, the proportion of salt increase.

Question 2.
The temperature in coastal areas remains equable.
Answer:

(i) In regions close to the oceans, seas or large reservoirs, there is not much of a difference in the temperature throughout the day.

(ii) The main reason for this is the mixing of vapour released through evaporation of water from these water bodies into air.

(iii) This vapour in the air absorbs and stores the heat released from the land.

(iv) Hence, the temperature in coastal regions remain equable.

Question 3.
It is economic to carry out transport by water ways.
Answer:

• Waterways is a cost-effective, fuel efficient and relatively more environment friendly means of transportation.
• Large scale transport of goods can be carried out with the help of ships, trawlers, boats, etc. at a low cost.
• So it is economic to carry out transport by waterway.

Question 4.
There is a difference in the climate of regions close to the oceans and regions far away from the oceans.
Answer:
(i) The oceans influence the climatic condition of a place. Coastal areas are cooler and wetter than regions away from the ocean.

(ii) There is a difference in the maximum and minimum temperature with the difference being less in coastal region (nearness to the sea) while it is more in the region far away from the sea (continentality).

(iii) The temperature in coastal areas remains equable due to the mixing of vapour released through evaporation of water from these water bodies into air. This vapour absorbs and stores the heat released from the land.

Question 5.
Oceans act as the controller of global temperature.
Answer:

(i) Winds move the oceanic water in the form of currents.

(ii) Ocean currents move from the equatorial region to polar regions and from polar regions to the equatorial region.

(iii) This leads to the redistribution of heat on the earth.

(iv) The cold currents moving towards the equatorial region making the temperature of coastal areas in that zone milder whereas the warm currents coming in the colder region cause the temperature in coastal areas to rise. Hence, the oceans act as the controller of global temperature.

Answer the following questions in brief:

Question 1.
What are planetary winds?
Answer:

• Equatorial regions receives perpendicular sunrays.
• As a result these areas get more heat whereas the polar regions receive highly slant rays.
• This differential heating creates imbalance in the temperature of air in different parts leading to formation of belts of high and low pressure on earth.
• Winds blow1 due to the pressure differences in these belts. These winds are called Planetary Winds.

Question 2.
Write in brief about oceanic transport.
Answer:

• Oceans have provided us the most economic option of transportation.
• Large scale transportation of goods is carried out with the help of ships, trawlers, boats, etc.
• International trade is carried out on a large scale using waterways.
• Countries like Spain, Norway, Japan have a good coastline due to which goods are transported by ocean routes, making these countries important.

Question 3.
How do ocean currents aid water transport?
Answer:

• Ocean currents are quite important in water transport.
• As far as possible water transport is carried out along ocean currents.
• They accelerate the speed of the ships and also save fuel to a considerable extent.

Question 4.
List the causes that lead to large scale pollution of oceanic water.
Answer:
The causes that lead to large scale pollution of oceanic water are:

• Oil spills.
• Releasing the waste produced in the coastal cities into the seas.
• Materials thrown out from ships.

Give geographical reasons for the following statements:

Question 1.
There is unequal distribution of heat received from the Sun.
Answer:
The unequal distribution of heat received from the Sun is because:

• The earth is spherical in shape.
• The rays which fall on the equator are straight, occupy less area and give more heat.
• The rays which fall on the curvature i.e., on the polar regions are slant rays which occupy large area and give less heat.

Question 2.
The temperature near the sea level is higher and it decreases in the mountainous region.
Answer:

• Firstly, the sea water gets heated by the rays of the sun.
• The absorbed heat is later radiated into the atmosphere.
• So, the layer of air close to the surface gets heated.
• This heat gets transferred vertically to the adjacent upper layers of air.
• Therefore, the temperature near the sea level is higher and it decreases at the mountainous region.

Question 3.
In the coastal areas, as compared to continental areas, the temperature of air is lower during the day but warmer at night.
Answer:

• There is difference in the heating and cooling of land and water.
• The air over the land gets heated faster and also cools rapidly.
• The air over the water gets heated slowly and also loses the heat in a slower manner.
• The temperature of air is lower during the day but warmer at night, in the coastal areas when compared to continental areas.

Question 4.
Greenhouse gases lead to increasing temperature of the earth.
Answer:

• Some gases in the atmosphere like carbon dioxide and water vapour can hold the heat within themselves for a long period of time.
• Due to the gases, the temperature of air in the atmosphere increases.
• Thus, greenhouse gases lead to increasing temperature of the earth.

Question 5.
Regions, where warm and cold currents converge, are favourable for the growth of fisheries.
Answer:

• Regions, where warm and cold currents converge, are favourable for the growth of planktons.
• Planktons are the food for fishes.
• Fishes travel here in large numbers.
• They breed in warm waters and increase the number of fishes.
• Therefore, regions where warm and cold currents converge favour the growth of fisheries.

Answer the following questions in short:

Question 1.
Explain the movement of ocean currents from equator to the polar region.
Answer:
Due to temperature differences, both upward and horizontal currents develop in the ocean. Besides temperature differences, factors like winds and differences in the density of water also give rise to horizontal currents. These ocean currents flow from the equator to the polar region and from the polar region to the equator.

Question 2.
Explain the effect of the ocean current flows from the frigid to the torrid zone.
Answer:
When an ocean current flows from the frigid to the torrid zone, it reduces the temperature of the coasts in the torrid zone. When a current flows from the torrid to the frigid zone, it increases the temperature of the coasts in the frigid zone.

I can do this!

Question 1.
Identify the temperature zones.
Answer:
There are three temperature zones namely torrid, temperate and frigid zones.

Question 2.
Tell the factors influencing temperature.
Answer:
Factors influencing temperature are latitude, winds, nearness to the sea, continentality, vegetation cover, cloud cover, physical set up, height above sea level and industrialisation.

Question 3.
Describe the global distribution of temperature with its characteristics.
Answer:
The isotherms in the southern hemisphere are fairly parallel to the latitudinal lines. From South Pole to the Tropic of Capricorn the distance between these lines is almost equal. As the proportion of land in the southern hemisphere is limited, temperatures in these parts are largely influenced by latitude.

In the northern hemisphere, the distance between these lines varies. In this hemisphere, the proportion of land is comparatively greater. This affects the distribution of temperature. These effects are seen in the form of variations in the distance between the isotherms and curved nature of these lines.

Question 4.
Describe the structure of a thermometer.
Answer:
A vacuum glass tube is filled with mercury or alcohol is mounted on a wooden board. There are two temperature scales showing Celsius and Fahrenheit.
