if a river continual flows into the sea, how does the sea never overflow?

Answer 1

The seas are constantly evaporating, forming clouds which rise, cool and produce rain, hail and snow that falls onto the land (and back into the seas). On the land, rivers form and return water to the seas. A global balance between evaporation and condensation takes place. Unfortunately, some areas of land get too little rain and others too much.

The total amount of water in the form of liquid, solid and vapour in and on the earth never changes.
However, due to global warming, the icecaps (North and South) are apparently diminishing and sea levels are rising somewhat but still, the amount of water remains the same.

Answer 2

The heat of the sun evaporates the sea water, forming clouds which the wind blows over the land. When the clouds cool, they condense, and fall as rain, which runs into the rivers.

Ecclesiastes wondered about this too, nearly 3000 years ago, but he knew the answer. In chapter 1, verse 7, he says:

"All the rivers run into the sea, yet the sea is not full; unto the place from whence the rivers come, thither they return again."

Answer 3

Hmm sounds like you never took a geography class !
River flows into the sea and where do you think river water comes from: (hint: the stuff that falls from the Clouds-RAIN !)
Where do the Clouds come from? From evaporation of the ocean and lakes, or moist ground. So it is an endless cycle ! Ocean->Clouds->Rain->River->Ocean.

Answer 4

Because the sun warms up the sea which then evaporates and turns in to clouds which then turn into rain which falls into rivers which flow into the sea which is warmed up by the sun....etc.

Answer 5

Evaporation.
Someone said that sea levels are rising but the Mediterranean Sea is actually falling because the amount of water that is being used on land before it gets to the sea.

Answer 6

it all collects in a big lump at one side of the ocean, until the weight is too great to support, then it goes rushing round the world in a big tidal wave. This is known to earth scientists as 'the great spin cycle'. The earth recovers quickly, but its rotation is erratic, causing the water to flatten, allowing land areas to drain. This is known as 'tumble drying'. The cycle is due again on August 15th. Anyone care to help build an ark?

Answer 7

Umm.... It's called the water cycle. The water evaporates into the air and forms clouds. This is not a new thing, it has been happening since water started existing.

Answer 8

The water cycle:

Sea water evaporates.
It rains over land.
The water collects into rivers.
The rivers empty into the sea.
The cycle starts again.

Answer 9

Where do you think the river came from in the first place.?

Answer 10

Fish drink it

we are fishing a lot so there are less fish in the sea

thats why the sea is rising..
