Question

The _______ acts as a barrier to the Southeast Trade winds.
A. Great Escarpment of Brazil
B. Brazilian Highlands
C. Brazilian Plains
D. Brazilian Islands

Answer 1

Hint: - The geographical feature that acts as a barrier to the Southeast trade winds lies at the eastern boundary of Brazil. It is an area of the earth where elevation changes abruptly.
-Its elevation is about 790m.

Complete answer:
Let us review the options and discuss the answer.

Option A. The eastern side of the Brazilian Highlands is differentiated by the Great Escarpment having an elevation of 790m. The Escarpment goes about as a boundary toward the Southeast trade winds and causes orographic sort of precipitation in the beachfront locale. Beyond the highlands, the impact of these breezes gets diminished prompting insignificant precipitation. A rain shadow area is formed toward the northeast of the ledge. Thus, it is the correct option.
Option B. Brazilian Highlands is one of the important features of Brazil. It is the source of mineral wealth in the country. It is also known as Brazilian Plateau. It does not act as a barrier to the trade winds. Thus, it is an incorrect option.
Option C. Brazilian plains or the Pampas are the most fertile land in the country. It is the breadbasket of the country. It has no part in acting as a barrier as it is a low lying land. Thus, it is an incorrect option.
Option D. There are various islands surrounding Brazil. They lie to the east of the great escarpment and do not have any mountainous terrain higher than the escarpment. So they do not act as a barrier. Thus, it is an incorrect option.

Additional Information
The Serra do Mar, or "Mountain Range of the Sea" is an extraordinary slope on the eastern edges of the Brazilian Highlands, which slip suddenly to the Atlantic coast. It stretches out for around 1,600 miles (2,600 km) from the Rio Grande do Sul Estado (express) as far as possible toward the north to Bahia state.

Based on the above explanation, the correct answer is Option A.

-Over 60% of Brazil is covered by the plateaus. The Brazilian Highlands cover a large portion of the central, eastern, and southern pieces of the nation.
-Brazil's coast is toward the east and outskirts of the Atlantic Ocean. A significant part of the coast is portrayed by the Great Escarpment which resembles a huge monumental divider.
-Brazil has most of the Amazon Rainforest.
