Is the Arabian peninsula more plains hills and low tablelands or mouintainous?

The Arabian Peninsula is primarily characterized by vast desert plains and arid regions, along with some low tablelands. While it does have mountain ranges, such as the Sarawat Mountains in the west and the Hajar Mountains in the east, these areas are not as extensive compared to the overall flat and elevated plains of the region. Thus, the peninsula is more dominated by plains and low tablelands than by mountainous terrain.
