Final answer:
The Altiplano Region is a high-altitude plateau that encompasses La Paz, El Alto, and Lake Titicaca in Bolivia. Lake Titicaca is the world's highest navigable lake and creates a unique climate for agriculture in the surrounding area. This region has a rich historical significance with ancient civilizations like the Tiwanaku Empire.
Step-by-step explanation:
The high-altitude plateau lying mostly in Bolivia that includes the cities of La Paz and El Alto, as well as Lake Titicaca, is known as the Altiplano Region. This region is a wide basin situated between two main Andean mountain ranges and is famously known for housing Lake Titicaca, the highest-elevation navigable lake in the world.
With a history dating back to ancient civilizations, the Altiplano has supported human habitation for thousands of years, evidenced by sites such as Tiwanaku and its terraced agriculture that surrounds the lake.
Lake Titicaca itself is a remarkable freshwater lake with a surface at an elevation of 12,000 feet above sea level. Despite the high altitude, the lake's ability to absorb solar energy and redistribute it as heat during the night allows for moderate temperatures that are conducive to agricultural practices, making the land around it ideal for farming.
This unique climate, combined with the rich cultural heritage and natural resources, make the Altiplano Region an important area both historically and economically.
