Answer: Evaporation and soil infiltration.
Step-by-step explanation:
Most of the water in the desert are evaporated due to the high temperature. The water is evaporated due to the heat which is generated from the sun.
The temperature is so high and there is no such cooling factor there which leads to the drying of the water bodies there.
Soil infiltration can be defined as the ability of the soil to store water in it. The soil there absorbs and does not allows it to move further into the ocean.
