Headland

Last updated

A headland is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape. [1] Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff.

Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the headlands, coastlines eventually straighten out then start the same process all over again.

Geography of Mozambique

The geography of Mozambique consists mostly of coastal lowlands with uplands in its center and high plateaus in the northwest. There are also mountains in the western portion. The country is located on the east coast of southern Africa, directly west of the island of Madagascar. Mozambique has a tropical climate with two seasons, a wet season from October to March and a dry season from April to September.

Geography of South Africa geography of South Africa

South Africa occupies the southern tip of Africa, its coastline stretching more than 2,850 kilometres from the desert border with Namibia on the Atlantic (western) coast southwards around the tip of Africa and then northeast to the border with Mozambique on the Indian Ocean. The low-lying coastal zone is narrow for much of that distance, soon giving way to a mountainous escarpment that separates the coast from the high inland plateau. In some places, notably the province of KwaZulu-Natal in the east, a greater distance separates the coast from the escarpment. Although most of the country is classified as semi-arid, it has considerable variation in climate as well as topography. The total land area is 1,220,813 km2 (471,359 sq mi). It has the 23rd largest Exclusive Economic Zone of 1,535,538 km2 (592,875 sq mi).

Cape (geography) A large headland extending into a body of water, usually the sea

In geography, a cape is a headland or a promontory of large size extending into a body of water, usually the sea. A cape usually represents a marked change in trend of the coastline which makes them prone to natural forms of erosion, mainly tidal actions. This results in capes having a relatively short geological lifespan. Capes can be formed by glaciers, volcanoes, and changes in sea level. Erosion plays a large role in each of these methods of formation.

The Canadian territory of Nunavut covers about 1.9 million square kilometres of land and water including part of the mainland, most of the Arctic Islands, and all of the islands in Hudson Bay, James Bay, and Ungava Bay which belonged to the Northwest Territories. This makes it the fifth largest country subdivision in the world. If Nunavut were a country, it would rank 13th in area, after the Democratic Republic of the Congo. Nunavut has land borders with Manitoba, the Northwest Territories on several islands as well as the mainland, and a tiny land border with Newfoundland and Labrador on Killiniq Island. Nunavut also has small land borders with Ontario and Quebec.

Killiniq Island small, remote island in northeastern Canada

Killiniq Island is a small, remote island in northeastern Canada. Located at the extreme northern tip of Labrador between Ungava Bay and the Labrador Sea, it is notable in that it contains the only land border between Nunavut territory and the province of Newfoundland and Labrador. Most other islands off the northern coast of Quebec and Labrador belong exclusively to Nunavut. Some cartographic sources do not correctly show the island's geopolitical boundaries, for instance the Commission de toponymie du Québec seems to show it belonging to Quebec.

Mistaken Point Ecological Reserve protected area in Newfoundland and Labrador, Canada

Mistaken Point Ecological Reserve is a wilderness area and a UNESCO World Heritage Site located at the southeastern tip of Newfoundland's Avalon Peninsula in the Canadian province of Newfoundland and Labrador. The reserve is home to the namesake Mistaken Point Formation, which contains one of the most diverse and well-preserved collections of Precambrian fossils in the world. Ediacaran fossils discovered at the site constitute the oldest known remnants of multicellular life on Earth.

Ponta do Sinó

Ponta do Sinó is the southernmost point of the island of Sal in Cape Verde. It lies 2 km southwest of Santa Maria city centre. The area north of the headland is a protected area: nature reserve Ponta do Sinó, at the edge of a large tourism development zone. There is a lighthouse on the headland, Farol da Ponta do Sinó, built in 1892.

Ponta do Sol (Santo Antão promontory)

Ponta do Sol is the northernmost point of both Cape Verde and the Island of Santo Antão. It is located 300 meters north of the city center of Ponta do Sol. The former Agostinho Neto Airport was located on the headland.
