Question

how do people live on a plateau

Answer 1

PLATEAUS ARE SCULPTED by geologic forces that lift them up and the wind and rain that wear them down into mesas, buttes, and canyons. Monument Valley and the Grand Canyon, both icons of the American Southwest, were chiseled from the Colorado Plateau.

Plateaus are built over millions of years as pieces of Earth's crust smash into each other, melt, and gurgle back toward the surface. Some owe their creation to a single process; others have been subjected to more than one during different epochs of Earth's history.

The highest and biggest plateau on Earth, the Tibetan Plateau in East Asia, resulted from a collision between two tectonic plates about 55 million years ago. The land buckled up along the seam of the collision and formed the Himalaya mountain range. Farther away, the crust uplifted but didn't crumple and wrinkle, creating instead a raised, flat, and wide open

Formation From Under the Earth's Surface

Many plateaus form as magma deep inside the Earth pushes toward the surface but fails to break through the crust. Instead, the magma lifts up the large, flat, impenetrable rock above it. Geologists believe a cushion of magma may have given the Colorado Plateau its final lift beginning about ten million years ago.



Repeated lava flows that spill out from cracks in the ground and spread out over hundreds of square miles can also slowly build up massive plateaus. The Columbia Plateau in the U.S. Pacific Northwest and the Deccan Plateau of west-central India were formed by these runny lava flows.

Plateaus also form in the ocean, such as the Mascarene Plateau in the Indian Ocean, one of the few underwater features clearly visible from space. It extends approximately 770 square miles (2,000 square kilometers) between the Seychelles and Mauritius Islands.

The Power of Wind and Water

Other plateaus are created over time as wind and rain wear away the side of an uplifted region, giving it geographic distinction from the surrounding terrain. Wind and rain eventually wear plateaus down to mesas and buttes and sculpt odd landforms like the arches and hoodoos found in southern Utah's famed national parks.

Water is the greatest erosive force on plateaus. As they course along, rivers carve valleys into the rock, washing the sediment toward the sea. Over time, these valleys become giant, majestic chasms like the Grand Canyon, which is continually carved by the Colorado River

Answer 2

they live by eating food and enjoying the weather as so cool by wearing sweaters as the temperature is very less there
