The Tuwaiq Mountains are a prominent mountain range located in central Saudi Arabia. Stretching approximately 1,000 kilometers, they are characterized by steep cliffs and rugged terrain. The mountains are primarily composed of limestone and are known for their unique geological formations, which include deep canyons and plateaus. These mountains play a significant role in the region's ecology and climate. They create a natural barrier that influences weather patterns, leading to varying rainfall levels on either side. The Tuwaiq Mountains are also home to diverse flora and fauna, making them an important area for biodiversity in the Arabian Peninsula.
