Question 3. Give an account of the humid Pampas and the dry Pampas.
Answer:

Humid Pampas And The Dry Pampas:-

The word ‘Pampas’ has originated from the Spanish word Pampa, meaning ‘uninterrupted extensive plainland’. The vast grassland that surrounds the capital of Argentina, Buenos Aires, in a half-moon shape, is called the Pampas.

The eastern part of the Pampas receives a comparatively higher amount of rainfall which helps in the growth of tall grasses. Therefore, this region is referred to as the humid Pampas.

The western part of the grassland is situated in the interior part of the continent, away from the sea. So, it receives less amount of rainfall, which leads to the growth of short grasses.

Hence, the western part is referred to as the dry Pampas. The Pampas grassland is famous for cattle rearing and the system of cattle-rearing followed in this region is the best in South America.
