Consider the following statements: Assertion (A): The eastern coasts ...
Assertion (A): The eastern coasts of continents within the tropics have much heavier rainfall than the interiors of the west coasts.
Reason (R): All western coasts fall in the rain shadow zone.
The correct answer is option 'C', which states that Assertion (A) is correct, but Reason (R) is incorrect.
Explanation:
Eastern Coasts of Continents within the Tropics have Heavier Rainfall:
- The eastern coasts of continents within the tropics, such as the eastern coast of India or the eastern coast of Africa, receive heavier rainfall compared to the interiors of the west coasts.
- This is due to the prevailing wind patterns in the tropics, specifically the trade winds.
- The trade winds blow from east to west in the tropics, carrying moist air from the oceans towards the western coasts of continents.
- As the moist air encounters the landmass, it is forced to rise, leading to the formation of clouds and subsequent rainfall along the western coasts.
- This phenomenon is known as orographic rainfall, where the moist air is lifted over a mountain or elevated terrain, resulting in enhanced precipitation.
- As a result, the western coasts of continents within the tropics receive significant rainfall.
Rain Shadow Zone:
- The rain shadow zone refers to the area that lies on the leeward side of a mountain range or elevated terrain.
- When moist air is lifted over a mountain range, it cools and condenses, leading to rainfall on the windward side of the mountain.
- However, as the air descends on the leeward side, it warms and dries up, resulting in reduced rainfall and arid conditions.
- This creates a rain shadow zone, which is characterized by low precipitation and dry climate.
- The rain shadow effect is prominent on the leeward side of mountain ranges, where the prevailing winds are blocked by the mountains, preventing the moist air from reaching the area.
Reason (R) is Incorrect:
- While it is true that western coasts often experience the rain shadow effect, it is not true that all western coasts fall in the rain shadow zone.
- There are several factors that determine the occurrence of the rain shadow effect, including the direction of prevailing winds, the height and orientation of the mountain range, and the distance from the coast.
- In some cases, the western coasts may not be affected by the rain shadow effect and may receive significant rainfall due to other atmospheric factors or geographical features.
Conclusion:
- The assertion that the eastern coasts of continents within the tropics have heavier rainfall than the interiors of the west coasts is correct.
- However, the reason that all western coasts fall in the rain shadow zone is incorrect, as it does not consider the various factors that determine the occurrence of the rain shadow effect.
Reason (R): All western coasts fall in the rain shadow zone.
The correct answer is option 'C', which states that Assertion (A) is correct, but Reason (R) is incorrect.

Consider the following statements: Assertion (A): The eastern coasts ...
- Islands and coastal areas 10° to 20° north or south of the equator usually have a tropical marine climate. The ocean is the mam's influence in creating the tropical marine climate.
- The temperature ranges from 25 °C to 35°C. The trade winds blow all year round. The trade winds are moist, as they have passed over warm seas. Since they are easterlies, they cause greater precipitation on the eastern coasts and run dry on the western coasts and interiors.
