Does the full moon affect tides?

Does the full moon affect tides?

When the earth, moon, and Sun line up—which happens at times of full moon or new moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides. When lunar and solar tides act against each other, the result is unusually small tides, called neap tides.

What does OTEC stand for *?

Ocean Thermal Energy Conversion (OTEC) is a unique source of renewable energy that provides stable power, 24 hours a day, 365 days a year, and does not require energy storage systems.

What is the basic principle of OTEC?

Working principle OTEC uses the ocean’s warm surface water with a temperature of around 25°C to vaporize a working fluid, which has a low-boiling point, such as ammonia. The vapor expands and spins a turbine coupled to a generator to produce electricity.

How efficient is OTEC?

The maximum possible Carnot thermal efficiency of an Ocean Thermal Energy Conversion (OTEC) power system is about 7% as it exploits the water temperature gradient between the surface and the deep ocean, which is only slightly over 20 degree C in tropical waters.

What is open cycle OTEC?

An OTEC system in which warm, surface seawater is the working fluid. In open-cycle ocean thermal energy conversion, warm, surface seawater is placed in a low-pressure container that causes the water to boil, turning a turbine as the steam expands.

Does India have a tidal power plant?

According to the estimates of the Indian government, the country has a potential of 8,000 MW of tidal energy. This includes about 7,000 MW in the Gulf of Cambay in Gujarat, 1,200 MW in the Gulf of Kutch and 100 MW in the Gangetic delta in the Sunderbans region of West Bengal.

Why are there 2 tidal bulges?

Gravity and inertia act in opposition on the Earth’s oceans, creating tidal bulges on opposite sites of the planet. Because water is fluid, the two bulges stay aligned with the moon as the Earth rotates (Ross, D.A., 1995). The sun also plays a major role, affecting the size and position of the two tidal bulges.

What will happen if the Earth stops rotating?

If the Earth were to stop spinning on its axis, gradually the oceans would migrate towards the poles from the equator. You could travel around the Earth on the equator and stay entirely on dry land—ignoring the freezing cold on the night side, and the searing heat on the day side.

How long can Earth last?

One billion years from now, Earth’s atmosphere will contain very little oxygen, making it uninhabitable for complex aerobic life. Today, oxygen makes up around 21 per cent of Earth’s atmosphere.

How much longer will Earth be habitable for humans?

This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet’s habitability.

Will the earth ever run out of drinkable water?

While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.

Do we drink same water as dinosaurs?

As water on the surface of lakes, oceans, and rivers warms up, it travels into the atmosphere as vapour. Because of the way this water cycle has always circulated our planet, there is indeed a chance that the water in your glass is the same water that thirsty dinosaurs were drinking about 65 million years ago.

Who created water on Earth?

Key points: Water is abundant in space but it was thought that Earth was dry when it formed. A new study shows that meteorite rocks of the type that built the Earth contain the building blocks of water. This means that water formed on Earth from day one rather than being a later addition.

How old is the water in the ocean?

4 billion years
