Hong Kong has a total area of 1,108 km2 (428 sq mi), of which 3.16% is water. 60 islands are dispersed around Hong Kong, the largest of which by area is Lantau Island, located southwest of the main peninsula. Lantau Island and the majority of the remaining islands are parts of the New Territories, an area that also encompasses the hilly terrain north of Kowloon. Hong Kong Island is separated from Kowloon by Victoria Harbour, a natural harbour. The Kowloon Peninsula to the south of Boundary Street, and New Kowloon and the New Territories to the north of Boundary Street were added to British Hong Kong in 1860 and 1898, respectively.
Further from Victoria Harbour and the coast, the landscape of Hong Kong is fairly hilly to mountainous with steep slopes. The highest point in the territory is Tai Mo Shan, at a height of 958 metres in the New Territories.[1] Lowlands exist in the northwestern part of the New Territories. Portions of land on Hong Kong Island and the New Territories are reserved as country parks and nature reserves.
With the fourth-highest population density in the world at 6,300 people per square kilometre, Hong Kong is known for its shortage of residential space. Hong Kong has undergone several land reclamation projects to provide more space for residential and economic purposes, increasing its land area. This has caused the distance between Hong Kong Island and Kowloon to decrease. Hong Kong International Airport is the sole public airport in the territory, and is mostly located on reclaimed land on the island of Chek Lap Kok.
Politically, Hong Kong is divided into 18 districts, each having a district council. Nevertheless, most public services operate across the territory, and travel between the districts is not restricted. Sha Tin is the most populous district as of 2019.
The name "Hong Kong", literally meaning "fragrant harbour", is derived from the area around present-day Aberdeen on Hong Kong Island, where fragrant wood products and incense were once traded.[2] The narrow body of water separating Hong Kong Island and Kowloon Peninsula, Victoria Harbour, is one of the deepest natural maritime ports in the world.
Hong Kong's climate is subtropical and monsoonal (Köppen: Cwa), with cool dry winters and hot and wet summers. As of 2006, its annual average rainfall is 2,214 mm (87.2 in), though about 80% of the rain falls between May and September. It is occasionally affected by tropical cyclones between May and November, most often from July to September. The mean temperature of Hong Kong ranges from 17 °C (62.6 °F) in January and February to 29 °C (84.2 °F) in July and August.[3]
January and February are cloudier, with occasional cold fronts followed by dry northerly winds. It is not uncommon for temperatures to drop below 10 °C (50 °F) in urban areas. Sub-zero temperatures and frost occur at times on high ground and in the New Territories. March and April can be pleasant although there are occasional spells of high humidity. Fog and drizzle are common on high ground which is exposed to the southeast. May to August are hot and humid with occasional showers and thunderstorms. Afternoon temperatures often exceed 31 °C (87.8 °F) whereas at night, temperatures generally remain around 26 °C (78.8 °F) with high humidity. In November and December there are pleasant breezes, plenty of sunshine and comfortable temperatures.[4]

Hong Kong is on China's southern coast, 60 km (37 mi) east of Macau, on the east side of the mouth of the Pearl River estuary. It is surrounded by the South China Sea on all sides except the north, which neighbours the Guangdong city of Shenzhen along the Sham Chun River. The territory's 2,755 km2 (1,064 sq mi) area consists of Hong Kong Island, the Kowloon Peninsula, the New Territories, Lantau Island, and over 200 other islands. Of the total area, 1,073 km2 (414 sq mi) is land and 35 km2 (14 sq mi) is water.[5] The territory's highest point is Tai Mo Shan, 957 metres (3,140 feet) above sea level.[6] Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout the New Territories.[7] Much of this is built on reclaimed land, due to the lack of developable flat land; 70 km2 (27 sq mi) (six per cent of the total land or about 25 per cent of developed space in the territory) is reclaimed from the sea.[8]
Undeveloped terrain is hilly to mountainous, with very little flat land, and consists mostly of grassland, woodland, shrubland, or farmland.[9][10] About 40 per cent of the remaining land area is country parks and nature reserves.[11] The territory has a diverse ecosystem; over 3,000 species of vascular plants occur in the region (300 of which are native to Hong Kong), and thousands of insect, avian, and marine species.[12][13]

Hong Kong's terrain is hilly and mountainous with steep slopes. There are lowlands in the northern part of Hong Kong. A significant amount of land in Hong Kong, especially on the Hong Kong Island and the Kowloon peninsula, is reclaimed.
The lowest elevation in Hong Kong is in the South China Sea (0 m)[dubious – discuss] while the highest elevation is at Tai Mo Shan (957 m (3,140 ft)) in Tsuen Wan, the New Territories.
The natural resources of Hong Kong can be divided into three main categories:
Metalliferous minerals and non-metalliferous industrial minerals in the onshore area;
Quarried rock and building stone;
Offshore sand deposits.
Despite its small size, Hong Kong has a relatively large number of mineral occurrences. Some mineral deposits have been exploited commercially. Metalliferous mineral occurrences are grouped into four broad categories: tin-tungsten-molybdenum mineralisation, copper-lead-zinc mineralisation, iron mineralisation and placer deposits of tin and gold. Mesozoic igneous activity is largely responsible for this diversity of mineral deposits and the mineral concentrations have been variably enhanced by hydrothermal activity associated with faulting. Concentrations of non-metalliferous minerals that have been commercially exploited include kaolin clay, feldspar, quartz, beryl and graphite.[15]
For many years, granite and volcanic rocks have been quarried locally for road base metal, riprap, armour stone and asphalt, although the main purpose now is for concrete aggregates. At present, there are three quarries operating in Hong Kong. These are principally in granite and are located at Lam Tei, Shek O and Anderson Road. All the quarries are in the process of rehabilitation and have a life expectancy of between two and eight years.[15]
Offshore sand bodies have been dredged for aggregate sand and reclamation fill in Hong Kong as the rate of urban development has increased.[16]
Additional natural resources include forest and wildlife.

Natural hazards
Tropical cyclones are frequent in Hong Kong during the summer months between June and August. Landslides are common after rainstorms.
