why are branches all at same level along shoreline of lake?

It is what is called a browse line. It's produced by deer or other large animals. The deer eat any branches that hang down low enough for them to reach and as a result the branches all grow at the same minimum height.

First spelling... W H A T\n\nNext, your answer.  They are areas of deposition at the outlet or leveling area of a river called the flood plain.

The water in the Great Lakes came from the end of the last major ice age. That entire regions was covered in thick, deep glaciers and when they all melted the Great Lakes were formed. Glacial ice was obviously frozen fresh water. I imagine rain keeps the water levels up.

Most of the boundaries are natural like rivers and other natural features.  After that it was based on trying to separate by the populations involved.

Because they are like creeks that have lots of branches that all end of at the big river.\nLike my money flowing faster and faster away all the time!\nAnd then there is those times when the floods just wipe me out!

In East Anglia in England, the land level has effectively been  falling; this is due to better drainage of the land. Land + water creates bogs and fens, but land without the water doesn't take up the same volume therefore the land falls.\n\nSomewhere in the fens there is an iron post called Holme Post. As the land has been drained so more and more of this spike is revealed. Its top is now fourteen foot about the level of the land. When it was first driven into the ground its top was flush with the ground surface. Hope this makes sense.

Because the sea level in the pacific is different than the sea level in the atlantic. Rather than having fast rapids flowing from one side to the other (more erosion and harder for ships to navigate), they have level sections of water separated by locks.

It comes from the fact that the "hypotenuse" of the two "triangles" is not a straight line segment.  It is actually two segments of similar, but not equal, slope.

Because of the pressure of water is more at the bottom of the dam. Think of the tonnes of water the dam is holding at the base. \n\nHope this helps...

The Pacific and Atlantic Oceans have different heights with the highest sea surface in the Western Pacific. But don't worry about all that Pacific water rushing into the Atlantic and flooding the Texas coast.\n\nAs far as equalizing levels, this has occurred but introduces an idea that many people find hard to imagine. The difference in heights is a result of a "dynamic equilibrium". Dynamic means changing, but equilibrium means balance, which we usually think of as no change. How can this be? Think of an unchanging balance as one like you can find on a scale where you place the same weight on both sides and it will balance -- always and forever. There is no new weight added or removed, no energy added or removed. This is Static equilibrium, an unchanging balance. A dynamic equilibrium involves the balance of changes. Imagine on your scale that you have cups instead of weights. Each cup the same size and is being dripped into and overflows but it will still balance if the fluid dripping in and out balances on both sides. Here there is a dynamic equilibrium with changes in mass or weight. If we want to imagine an equilibrium that also includes energy, let's have one side of the scale have a smaller cup than the other. Water drips in and overflows, but the two sides can never balance because the two cups can never hold the same amount of water. This gets a little complicated, so hang in there. The cups can't balance each other with weight alone. The lighter cup will go up and the heavy cup will go down. You can make a dynamic equilibrium by pushing down on the lighter cup. Now you have two cups with different amounts of water that balance. Hmmm? This can only happen with the addition of energy.\n\nThis is similar to how the sea surface heights can be different -- there is a dynamic equilibrium. It is indeed affected by the rotation of the Earth which is where some of the energy used to maintain the balance comes from. More comes from the Sun and its heat. The energy acts through winds on the sea surface and currents which tend to cause water to "pile up" where currents are swift. Imagine the surface of your morning juice in its cup. If you swirl that juice, the surface is no longer 'level' but slanted (and the slant rotates with the swirl). This slant is maintained as long as you continue to swirl the cup. You have an equilibrium that requires energy. The moment you stop adding energy by swirling, the surface of the juice levels out. It is now a static system with a static equilibrium that is simple to understand.\n\nThere is a huge science project (yes, scientists do science projects too) called TOPEX/Poseidon that looks at the sea surface (and other ocean information) from orbiting satellites. And there are oceanographers who specialize in studying the sea surface and what causes it to be different from flat. Some of this information is available on the Internet including really cool pictures made from satellite information.

I think it has to do with when lightening hits the surface of the water it dis purses, and weakens!!  The lightening stays on the surface!!  Have a Great Day!  MB

The seas, ocaena, rivers, and lakes of the world are all composed of similar material to different degrees. For example the Atlantic, Pacific and Indian Ocean all have different amounts of salt in them. When the Panama canal was built a division between the regions was seen. Not so much with eyes but with equipment. True, those who named regions of water may not have had any idea that they were slightly different but they are. On a ship it'll be pretty hard to tell which ocean you're in if you awoke from a concussion and just stared out at sea. Maritime borders are only used as a political tool. Every second some of teh ATlantic mixes with the Pacific and vice versa.

B) FALL. The reason is that while the stone is in the boat (or otherwise floating or being supported by a floating object), it is displacing water equal to its WEIGHT, but when fully immersed, it displaces water equal to its VOLUME. This is less water (since if a volume of water equal to the volume of the stone weighed as much or more than the stone, then the stone's density would be less than that of water, which it isn't), and therefore the total water level in the lake will go DOWN.\n\nTo the other answerers: shame on you for not thinking through the problem carefully enough.

Maybe you have a large ore deposit beneath your location. This could generate a strong field that the polarized molecules would be attracted to. If it's closer to the upper part of the hill and big enough, it could also provide a small amount of gravitational attraction that could be pulling the water uphill.\n\nThe gravitational field of the Earth varies from place to place at the surface. We see this all the time when we take very sensitive readings. It is possible that a gravitational anomalies can be enough to cause odd effects at the surface.

Deltas and Estuaries are created at the mouths of rivers.\nAnother landform that is created close to the mouth of a river is an ox bow lake.

Planar topology requires that all lines start and end in nodes and no two lines cross,as with polygonal objects. However, polygon information is not maintained. Withthe exception of polygon filling, planar and polygonal objects appear the same. Pla-nar topology may be appropriate for hydrology if no lakes are present. Planar topol-ogy may also be appropriate for road systems that lack underpasses and overpassesor other features that require network topology for correct representation. Note thepresence of nodes (red) at every position where lines would otherwise cross, as wellas at the dangling ends, in the roads at the left
