Why are deserts located at he Western Parts of the continentscouyntries?

earth rotates from west to east. so first the sun rays will fall on the eastern side of earth. as a result of high temperature , low pressure is created . low pressure will result in rainfall. as these moisture laden clouds will move ,there will be many obstructs on the way . so the western part will remain dry and hence we will find most deserts on the western sides of the continents.this is also because the winds blow from east and become dry by the time they reach in the western side. or

The largest hot desert in the world is the Sahara, and that's located on the north of a continent. The second largest is the Gobi, and that's in central Asia. The deserts of Australia are also central. Some deserts are on the western sides of continents, but it's not typical.
