What are positives and negatives on tidal?
the positives are no pollutionn woo the negatives are....you need water:(
Why do tidal energy stations depond on large differences in water height between high tide and low tide?
Because you need a change of height to make the water run downhill and power a turbine. But of course you only get the power when there is a height difference, so the aim is usually to build a barrage across the mouth of an inlet and let it fill as the water rises, then you can let it out gradually over a period.
Why do people that want to go deep underwater need a submarine or dive bell?
The pressure of the water that deep would crush a person.
What is the minimum tidal energy required for a practical tidal plant?
That depends on the kind of plant. There are two major types:1. Tidal turbines2. tidal barrages1. Tidal turbines are like wind-turbines but underwater. They need a current speed of at least 1m/s to start producing energy but current models are not economically viable for anything below 2m/s2. Tidal barrages are like dams across a bay or an estuary. Theyutilizethe difference in water level between high and low tide. They open their gates as the tide comes in to allow the water to collect behind the dam. at the highest point of the tide the gates close until low tide is reached. the water is then release via turbines until the water level behind the dam is equal to the sea level. When the tide comes in again the cycle repeats. These kind of tidal plants need a difference between high and low tide of at least 5-7 meters although the bigger the difference the better.
Why do people need tidal power?
Because a vast amount of water is lifted up as the moon passes and its gravitational influence is felt. Trap this water, wait for the surrounding water to fall and you have the basis for a hydroelectric plant.
Why draft tube is used in francis and kaplan turbine and not in pelton turbine?
The Kaplan turbine is a newer, more revolutionary version of the Francis turbine, which came before it. The draft tube is used so that the turbine does not need to be where the water flow is lowest.
How deep does a water Toby need to be?
As deep as it needs to be.

What is a deep water harbor?
This is deep water so ships can sail through. Becouse ships need deep water to sail through places
Can you do water aerobics in deep water?
Yes, but you need an aquabelt.
Does tidal mills make as much energy as tidal waves?
It's difficult to say. A tidal wave, or a tsunami, has an amazing amount of power, but it is all over in a hour or two. Tidal mills can capture the tidal water twice a day and use it to generate clean electricity. This will continue for ever (or until the turbines need to be replaced).

Why can't photosynthetic organisms grow in the deep water zone?
Photosynthetic organisms need light in order to survive. In very deep water there is no light.
Do we need tidal volume?
Yes.
Do wolffish live in shallow water or deep water?
I do not know and I need help finding the answerr
What two factors determine the density of water in deep currents?
I NEED THE ANSWER
When driving through deep water you need to?
Stop and back out. Find another route around the water.
