Answer» Correct Answer - Option 1 : lagoon
The correct answer is lagoon. - A lagoon is a shallow body of water that may have an opening to a larger body of water but is also protected from it by a sandbar or coral reef.
- Examples: Hilton Lagoon, Hawaii. The Venetian Lagoon. Lake Nokoue, Ganvie, Benin. Lake Piso, Liberia. Lycian Lagoon.
- The Venetian Lagoon is home to the "Queen of the Adriatic", the city of Venice, Italy.
- There are two types of lagoons: atoll and coastal.
- Atoll lagoons form when an island completely subsides beneath the water, leaving a ring of coral that continues to grow upwards.
- Coastal lagoons form along gently sloping coasts. They are generally shallower than atoll lagoons and tend to be separated from the ocean by an island, reef, or sandbank.
- Most coastal lagoons are connected to the ocean by an inlet.
| Glacier | - A glacier is a huge mass of ice that moves slowly over land.
- They are made up of fallen snow that, over many years, compresses into large, thickened ice masses. Glaciers form when snow remains in one location long enough to transform into ice.
- Presently, glaciers occupy about 10% of the world's total land area, with most located in polar regions like Antarctica, Greenland, and the Canadian Arctic.
| | Lake | - A lake is a body of water that is surrounded by land.
- Glacial lakes are common in North America as in other regions formerly traversed by the many glaciers of the last ice age.
- Another significant lake-forming force is the movement of the tectonic plates that form the Earth’s crust.
- Many lakes result from river movements of sediments that slowly create lakes over time.
| | Estuary | - Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea.
- Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of freshwater draining from the land and salty seawater.
