Dubai is located on the Persian Gulf coast of the United Arab Emirates and is approximately at sea level (16 m or 52 ft above). The emirate of Dubai shares borders with Abu Dhabi in the south, Sharjah in the northeast, and the Sultanate of Oman in the southeast. Hatta, a minor exclave of the emirate, is encompassed on three sides by Oman and by the emirates of Ajman (in the west) and Ras Al Khaimah (in the north). The Persian Gulf borders the western coast of the emirate. Dubai is positioned at 25.2697°N 55.3095°E and covers 1,588 sq mi (4,110 km2), representing a notable expansion beyond its initial 1,500 sq mi (3,900 km2) designation due to land reclamation from the sea.
Dubai lies directly within the Arabian Desert. However, Dubai’s topography is significantly different from that of the southern portion of the UAE. Many of Dubai’s scenery is highlighted by sandy desert patterns, while gravel deserts dominate much of its south region. The sand consists chiefly of crushed shell and coral and is accurate, clean and white. East of the city, the salt-crusted coastal plains, known as sabkha, give way to a north-south running line of dunes. Farther east, the dunes grow larger and are tinged red with iron oxide.
