Question

kya hota yadi dharti pe registan na hota

Answer 1

Because of the Earth's climate and landforms (especially mountains and basins) as they are today, it is not possible at this time for the Earth to not have any deserts. However, there were most likely time periods throughout the Earth's 4.56 billion year lifespan where there were no deserts.

The presence or absence of deserts do not really impact the Earth that much - the Earth is constantly changing (just at a rate far too slow for us to notice, except when an earthquake happens or a volcano erupts). If there were no deserts, all of the life (plants and animals) that are adapted to a desert environment would either 1) die, or 2) adapt to a different environment in order to survival


Deserts form because of the location of mountains and because of the way air circulates around the planet. There have been periods in the Earth's history in which there have been many fewer deserts than today, although the interiors of continents have essentially always been dry.

Asking what would happen if there were no deserts isn't really a meaningful question: deserts exist, always have, and always will. It's just how the atmosphere behaves.
