A groyne is a type of breakwater or jetty, which projects from the shore of a coast or river to block the movement of sediment. In rivers, they are called "wing dams" or spur dykes, and channel water into a faster-moving channel, usually in the center of the river.
Groynes are used along beaches to prevent the removal of sand, or conversely to prevent the deposition of sandbars along shore.
Which bay has the longest coastline in the world?
That depends on how you define bay. Probably the Bay of Bengal.
Are Ecuador's ocean waters warmer than Florida's?
No, not usually. Even though Ecuador is on the equator, the current next to the country brings in colder water from the Arctic. On the east coast of Florida, the Gulf Stream brings in much warmer waters from the tropics. It takes a long time for water to change temperature, so it usually reflects wherever it just came from.
Why are the white cliffs so white?
Erosion causes it to stay white as white. The Cliffs are made of chalk.
What are the stages of old harry rocks?
Old Harry Rocks located on the Jurassic Coast in England were originally a part of a chalk formation. Over time, erosion has worn away at the softer rock layers, creating three distinct formations: Old Harry, the lower Formation, and the Wave Cut Platform. These stages represent different periods of erosion and geological processes that have shaped the landscape over millions of years.
The word Indus is from the ancient Greek word "Indos", which is borrowed from the old Persian word "Hindus", and in turn derived from the Sanskrit word "Sindhu" . The "dhu" means a body of trembling water.
What are the warnings for a tsunami?
You can't really predict a tsunami, but If you hear about any underwater earthquakes or volcanic eruptions, that can sometimes mean there will be a tsunami.
Water has a much higher heat capacity than land, meaning that the ocean will retain the heat leftover from the summer and release it very slowly, even when it is very cold in the winter. Land, however, heats and cools very quickly, so land will always be quite cold in the winter. So if you live near the ocean, the relatively warm water will moderate air that flows over it, and this modified air will blow over coastal regions, making them milder than they otherwise would be.
What are disadvantages of atolls?
Fishing may not be that good because of the shallow water
The fact that there IS shallow water and isn't that great for swimming
Underpopulated so not much community
Rising sea levels put atolls in danger
During storms waves break off pieces of coral
What really causes whirlpools on the coast of Sicily?
The interaction of rising and falling tides can cause large rotating currents in the Coast of Sicily. The currents can reach 7 mph due to tide changes.
Do countries have population concentrated near coastlines or more inland?
Countries typically have populations concentrated near coastlines due to the accessibility of trade routes, resources, and favorable climates. Coastal areas often provide better economic opportunities, including fishing, tourism, and shipping industries. In contrast, inland regions may have lower population densities due to harsher environments and limited access to resources. However, this pattern can vary based on a country's specific geography, economic development, and historical factors.
How is the coastline of this volcanic island best described?
The coastline of a volcanic island is typically characterized by rugged cliffs, rocky shores, and unique geological formations such as lava tubes and sea stacks. Erosion from waves can create dramatic landscapes, including black sand beaches or steep, jagged coastlines. Additionally, volcanic activity may lead to the formation of new land, altering the coastline over time. Overall, the coastline reflects the island's dynamic geological history and natural beauty.
Do rainforests have coastlines?
Yes, rainforests can have coastlines, particularly tropical rainforests that are situated near the ocean. These coastal rainforests, such as those found in parts of Brazil, Indonesia, and Madagascar, often feature unique ecosystems that blend terrestrial and marine environments. The proximity to the ocean influences the climate and biodiversity, contributing to the rich variety of species found in these regions.
What industries are supported by the water surrounding SE Asia and coastlines?
The waters surrounding Southeast Asia support several key industries, including fishing, aquaculture, and tourism. The region is known for its rich marine biodiversity, making fishing and seafood production vital for local economies and food security. Additionally, coastal tourism thrives due to the area's beautiful beaches and vibrant marine ecosystems, attracting millions of visitors annually. Furthermore, shipping and maritime trade are crucial for economic connectivity, given Southeast Asia's strategic position in global trade routes.
