What's the biggest Desert in the world?

Question

with some details please

Answer 1

The Sahara Desert

The climate of the Sahara has undergone enormous variation between wet and dry over the last few hundred thousand years.[16] During the last ice age, the Sahara was bigger than it is today, extending south beyond its current boundaries.[17] The end of the ice age brought better times to the Sahara, from about 8000 BC to 6000 BC, perhaps due to low pressure areas over the collapsing ice sheets to the north.[18] Once the ice sheets were gone, the northern part of the Sahara dried out. However, not long after the end of the ice sheets, the monsoon, which currently brings rain only as far as the Sahel, came further north and counteracted the drying trend in the southern Sahara. The monsoon in Africa (and elsewhere) is due to heating during the summer. Air over land becomes warmer and rises, pulling in cool wet air from the ocean, which causes rain. Paradoxically, the Sahara was wetter when it received more solar insolation in the summer. Changes in solar insolation are caused by changes in the Earth's orbital parameters (9,000 years ago the Earth's axis had a stronger tilt than it does presently, and perihelion occurred at the end of July).[19]

Answer 2

sahara

Answer 3

Definition of "desert": a region so arid because of little rainfall that it supports only sparse and widely spaced vegetation or no vegetation at all

Therefore, Antarctica is the largest desert, followed by the Sahara.

Answer 4

The Sahara

The largest  desert in the world is the Sahara, in north Africa, which spans an area measured at roughly 3.5 million square miles.

The United States' contiguous 48 states could easily fit in the desert.

It spans more than 3,000 miles across Africa, stretching from the Atlantic Ocean to the Red Sea. It is bordered by the Mediterranean Sea on the north and it spreads all the way down to central Africa, some 1,200 miles south.
