Q about moon and sun tides, energy related to comet strikes and the mass water?

In summary, the moon and sun have gravitational pulls on Earth that create tides. The moon's pull is stronger due to its proximity to Earth, causing high tides when aligned and low tides when not. The sun also has an impact, especially during spring tides. Comet strikes can indirectly affect tides by altering the ocean floor or Earth's orbit. Tides can be harnessed as a source of energy, but can have negative impacts on marine life. The mass of water does not directly affect tides, but can impact the height of tides in certain areas. The shape of the coastline and ocean floor also play a role in tides.

rearth is the radius of Earth without tides. It has a potential, given by the gravitational field of earth. If you add the potential contribution from the moon, the potential will change. Try to determine the height h where the (new) potential is equivalent to the old potential at rearth.
 

Related to Q about moon and sun tides, energy related to comet strikes and the mass water?

1. How do the moon and sun affect tides on Earth?

The moon and sun both have gravitational pulls on the Earth, which creates tides. The moon's pull is stronger because it is closer to Earth. As the Earth rotates, the moon's pull causes the oceans to bulge, creating high tides. When the moon's pull is not directly in line with the Earth, the water is pulled away, creating low tides. The sun also has a smaller impact on tides, but it is mostly seen during spring tides and neap tides.

2. Is there a difference between tides caused by the moon and tides caused by the sun?

Yes, there are two types of tides: lunar tides and solar tides. Lunar tides are caused by the moon's gravitational pull, while solar tides are caused by the sun's gravitational pull. Lunar tides are stronger because the moon's pull is stronger and closer to Earth. However, the sun's pull also has an impact, especially during spring tides when the sun, moon, and Earth are aligned.

3. How does energy from comet strikes affect Earth's tides?

Comet strikes do not directly affect Earth's tides. However, they can indirectly cause changes in tides by altering the shape of the ocean floor or the Earth's orbit. These changes can impact the strength and frequency of tides. Additionally, comet strikes can also release large amounts of energy, which can cause tsunamis that can disrupt tides.

4. Can tides be used as a source of energy?

Yes, tides can be harnessed as a source of renewable energy. This is done by building tidal power plants that use the movement of the tides to generate electricity. Tides are predictable, making them a reliable source of energy. However, tidal power plants can have negative impacts on marine life and can be costly to build and maintain.

5. How does the mass of water affect tides?

The mass of water does not directly affect tides. The gravitational pull of the moon and sun are the main factors that determine tides. However, the amount of water in a specific area can impact the height of tides. For example, if there is more water in a bay or inlet, tides will be higher in that area compared to open ocean areas. Additionally, the shape of the coastline and ocean floor can also affect tides.
