Do coastlines stay the same?

The line where land meets water is constantly changing and reshaping. The coastline, that narrow strip of land that borders the sea along a continent or an island, is an ideal place to see a constantly-changing landscape. The nonstop wave action there means nothing ever stays the same.

Are all coasts the same?

Most people are surprised to learn that, just as the surface of the Earth is not flat, the surface of the ocean is not flat, and that the surface of the sea changes at different rates around the globe. For instance, the absolute water level height is higher along the West Coast of the United States than the East Coast.

What are the different coastlines?

There are five different coasts of the United States: the Atlantic Coast (East Coast), the Pacific Coast (West Coast), the Gulf Coast, the Arctic Coast, and lake states.

Why are coastlines uneven?

Sediment is moved along the coastline in a process known as longshore drift. ... This results in a zigzag motion as sediment is transported along the coastline. This process means that over time beaches can change shape.

Which country has the longest coastline?

Canada's Coastline: Canada's coastline is the world's longest, measuring 243,042 km (includes the mainland coast and the coasts of offshore islands). This compares with Indonesia (54,716 km), Russia (37,653 km), the United States (19,924 km) and China (14,500 km).

Where do waves begin?

Waves start out in the deep, open ocean as relatively vertical in shape, Presnell said. As a wave travels toward the shore, though, the bottom part of the wave drags along the ocean floor. The upper part of the wave above the water line starts to move faster than the rest of the wave.

How do humans use the coast?

Coastal land is used for human settlement, agriculture, trade, industry and amenity. The coastal sea presents problems related to transport, fishing, dumping, mining, etc., stemming from an intensification and diversification of ocean uses.

What level is sea level?

Mean sea level (MSL) (often shortened to sea level) is an average level of the surface of one or more of Earth's bodies of water from which heights such as elevation may be measured.

What kind of coastline has the same type of rock?

Coastlines where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines. A concordant coastline has the same type of rock along its length.

How many countries have a coastline in the world?

Data marked The World Factbook or TWF covers 198 countries and 55 territories, from the book published by the Central Intelligence Agency. In addition to coastline lengths, this is the source of the land area used to calculate the "coast/area ratio" for both TWF and WRI (see below) coastline measurement.

Is the length of the coastline always infinite?

As the length of a fractal curve always diverges to infinity, if one were to measure a coastline with infinite or near-infinite resolution, the length of the infinitely short kinks in the coastline would add up to infinity.

How to describe the coastal features of a map?

Coastlines where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines. A concordant coastline has the same type of rock along its length. Concordant coastlines tend to have fewer bays and headlands.
