228 Questions

Why are tides highest when the sun moon and earth are alinged?

When the sun, moon, and Earth are aligned, their gravitational forces combine to create higher high tides and lower low tides, a phenomenon known as spring tides. The gravitational pull of the sun and the moon reinforce each other, leading to more extreme tidal movements.

Does glaciers contain the highest percentage of fresh water on earth?

Yes, glaciers contain the largest percentage of fresh water on Earth, with around 69% of the freshwater stored in glaciers. This frozen water is vital for maintaining freshwater availability in rivers and lakes.

Would the tides be higher when the moon is on the same side of the earth as New Brunswick or on the opposite side?

The tides are higher when the moon is on the same side of the Earth as New Brunswick due to the moon's gravitational pull on the water, which causes a bulge in the ocean facing the moon. This is known as the force of attraction.

How is the fresh water replenished on earth?

In nature, "freshwater" is produced by the "water cycle" through the evaporation of "fresh or clean" water molecules from the contaminated surface water, and then the condensation of that water within the atmosphere, resulting in rain.

What place on earth has the highest tides in the world?

The Bay of Fundy in Canada is known to have the highest tides in the world, with tidal ranges reaching up to 53 feet (16 meters). The unique shape of the bay amplifies the tidal forces, resulting in these extreme tides.

What percent of earth hydrosphere is fresh water?

About 2.5% of Earth's hydrosphere is fresh water, with the majority of it found in glaciers and ice caps. Only a small fraction of this fresh water is readily accessible for human use in surface water bodies and groundwater.

What is the percentage of earth fresh water in the aquifer?

Approximately 30.1% of Earth's fresh water is stored in aquifers. These underground reservoirs are crucial for supplying water to wells and springs, as well as supporting ecosystems and human water needs.

How many fresh water seas are there on Earth?

There are five freshwater seas on Earth: the Caspian Sea, Lake Superior, Lake Victoria, Lake Huron, and Lake Michigan.

How much fresh water makes up the earth?

Ninety-eight percent of the water on the planet is in the oceans, and therefore is unusable for drinking because of the salt. About 2 percent of the planet's water is fresh, but 1.6 percent of the planet's water is locked up in the polar ice caps and glaciers. Another 0.36 percent is found underground in aquifers and wells. Only about 0.036 percent of the planet's total water supply is found in lakes and rivers. That's still thousands of trillions of gallons, but it's a very small amount compared to all the water available

Does Earth also causes tides on the Moon?

Yes, Earth does cause tides on the Moon. The gravitational pull of Earth causes the Moon's surface to bulge and create tides, although they are not as pronounced as the tides on Earth due to the Moon's composition and lack of large bodies of water.

What are the tides on earth mainly caused by?

Tides on Earth are mainly caused by the gravitational forces exerted by the Moon and the Sun. The gravitational pull of these celestial bodies creates bulges of water on Earth's surface, resulting in the regular rise and fall of the ocean levels.

How does fresh water cycle on earth?

The Earth makes sure that we get water because we can get it from lakes. Also we can get it form wells on the ground. All of these go right through your faucet all the time. It also is used again

How does the spin of the Earth create tides?

The moon's gravity pulls the water away from the earth on the side closest to it. Also the earth is pulled away from the water on the far side. These are the high tides. The sides that are perpendicular from the moon are the low tides. Because the earth spins once in a day whereas the moon takes a month to orbit this means there are 2 high and 2 low tides each day.

How would tides on earth be different if the moon revolved around earth in 15 days instead of 30 days?

If the moon revolved around Earth in 15 days instead of 30 days, tides would be more frequent, with high and low tides occurring twice a day rather than once. This faster orbit would lead to stronger tidal forces, resulting in more extreme tides. The tidal patterns would be more dynamic, potentially affecting coastal ecosystems and marine life differently.

What is the researched in each field astronomy hydrology meteorolgy geology?

In astronomy, researchers study celestial objects such as stars, galaxies, and planets to understand their properties and evolution. In hydrology, researchers investigate the distribution and movement of water on Earth, including its effects on ecosystems and human activities. In meteorology, researchers focus on the study of weather patterns, climate, and atmospheric conditions to improve forecasting accuracy and understand climate change. In geology, researchers study the Earth's history, structure, and processes, such as plate tectonics and rock formation, to comprehend its evolution and natural resources.

What percentage is earth fresh water?

Of all the water on Earth, around 2.75% of it is fresh drinking water.

What phase of the moon the highest and lowest tides on earth?

New and full moons produce the highest and lowest tides. These are called spring tides

What effect does this organization does Sun Earth and Moon and on Earth's tides?

The gravitational pull of the Sun and Moon on Earth creates tidal forces, leading to the rising and falling of ocean water levels known as tides. The Sun and Moon's alignment determines the intensity and timing of tides, with the gravitational influence of the Moon being stronger due to its proximity to Earth.

What is flood response in hydrology?

Flood response in hydrology is the process of managing and mitigating the impacts of flooding events. This involves monitoring and predicting flood events, issuing warnings to the public, implementing emergency response measures, and assessing flood damages. The goal of flood response is to protect lives, property, and the environment during and after a flood event.

How does industrialization affect hydrology?

Industrialization can lead to increased water pollution through the release of harmful chemicals and waste into water bodies. It can also increase water demand for manufacturing processes, leading to over-extraction of water resources. This can result in altered hydrological cycles, affecting water availability, quality, and ecosystem health.

How much of Earth does fresh water cover?

Fresh water covers approximately 0.7% of the Earth's surface, found in locations such as rivers, lakes, and groundwater. Most of Earth's water is found in oceans and seas, which are composed of saltwater.

What are The effects of the moon on the earth and tides?

The gravitational pull of the moon causes tides on Earth. When the moon is aligned with the Sun and Earth, we experience higher high tides (spring tides), while when the moon is at a right angle to the Sun and Earth, we experience lower high tides (neap tides). This gravitational force also creates tidal bulges on Earth, causing the oceans to rise and fall throughout the day.

How does position of the moon cause high and low tides on earth?

The gravitational pull of the moon affects the water on Earth, creating high tides on the side of the Earth facing the moon and on the opposite side. This is due to the difference in gravitational force across the Earth, resulting in areas experiencing high and low tides depending on the position of the moon relative to Earth.

How the oceans which are salty in nature are the source of fresh water on earth?

Oceans are not the source of fresh water on Earth. Drinking water primarily comes from 4 sources. Lakes, rivers, groundwater, and glaciers. (Of course, all of it is purified before it reaches you.)

ADDED: The oceans are fundamentally the source, because the water falling as rain and snow has been evaporated from the sea, and the evaporation leaves the salt behind.
