Final answer:
The geography of Peru includes a coastal region that is mostly desert due to the rain shadow effect of the Andes Mountains. Additionally, the waters along the coast are cold but rich in sea life, with occasional warm water during El Niño years.
Step-by-step explanation:
The correct answer is A. Its coastal region is comprised of desert.
The coastal region of Peru is largely desert due to the rain shadow effect of the Andes Mountains. The mountains block moisture from the Pacific Ocean, resulting in a dry and arid coastal region. This desert region is known as the Atacama Desert, which extends from northern Chile into southern Peru.
Additionally, the coastal region in Peru is influenced by cool ocean currents from the Antarctic, making the waters cold but rich in sea life. However, during El Niño years, warm water takes over, leading to die-offs of fish and flooding on the coast.
