Water Test - 3

The rhythmic rise and fall of ocean water twice in a day is called a tide. It is high tide when water covers much of the shore by rising to its highest level.

The water cycle is the process by which water continually changes its form and circulates between water bodies, atmosphere and land.

Swimmers float in dead sea because the increased salt content makes it dense.

Pacific ocean is the largest ocean in the world.

Generally, the warm ocean currents originate near the equator and move towards the poles. The cold currents carry water from polar or higher latitudes to tropical or lower latitudes.

Tides are rhythmic rise and fall of ocean water that occurs twice in a day. The strong gravitational pull exerted by the sun and the moon on the earth’s surface causes the tides.

The tsunami of 2004 caused wide spread damage in the coastal areas of India.

The process by which water continually changes its form and circulates between oceans, atmosphere and land is called water cycle.

Amazon river is in Africa.

Rivers, ponds and glaciers are sources of fresh water. But oceans don't have fresh water.

March 22 is celebrated as World Water Day when the need to conserve water is reinforced in different ways.

During a storm , the winds blowing at very high speed form huge waves. These may cause tremendous destruction.

The ocean bodies and the seas contain salty water. The water of the oceans is salty or saline as it contains large amount of dissolved salts.

Dead sea in Israel has salinity of 340 grams per litre of water. Swimmers can float in it because the increased salt content makes it dense.

A terrarium (plural: terraria or terrariums) is usually a sealable glass container containing soil and plants. Terraria are often kept as decorative or ornamental items.

Tsunami is a Japanese word from a double root: tsu, meaning port or harbour, and nami, meaning wave.

Waves,current and tides are different movements of ocean.But not wind.

The largest tsunami ever measured was 150m high.

Indira Point was a village in the Nicobar district at Great Nicobar Island of Andaman and Nicobar Islands, India. It was located in the Great Nicobar tehsil. It was the location of the southernmost point of India's territory.

Tsunami is a Japanese word that means “Harbour waves” as the harbours get destroyed whenever there is tsunami.

Tsunami or the harbor wave struck havoc in the Indian Ocean on the 26 December 2004. The wave was the result of the earthquake that had its epicenter close to the western boundary of Sumatra.

Winds, earthquakes, volcanic eruptions or underwater landslides are the factors affecting the height of the waves. The stronger the wind blows. The bigger the waves become.

97.3% of saline water is available on earth surface.

Falling of moisture in the form of rainfall, snow, fog, sleet and hailstone is termed as precipitation.

22 March is celebrated as World Water Day.

Waves are formed when winds scrape across the ocean surface.

Terrarium is an artificial enclosure for keeping small house plants.

The concentration of dissolved salt in a given volume of water is called salinity. Salinity is either expressed in grams of salt per kilogram of water or 1000 grams of water.

Generally, the warm ocean currents originate near the equator and move towards the poles. The cold currents carry water from polar or higher latitudes to tropical or lower latitudes.

Temperature, winds, gravitational pull of the sun, the moon, the earth and warm and cold currents are the factors that affect the movement of ocean water.
