The major type of weathering that takes place in a desert in Physical Weathering.

Explanation:  

Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.

In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.
