Why Summer Daylight is Longger than Winter Daylight
In the summer, the amount of daylight that we get is more than we get in winter. This is not because as much people think we are closer to the sun but because of the tilt of the earth.
The earth is actually closer to the sun in winter than it is in summer but you would be forgiven for thinking that this can not be true after looking out of your window on a cold and frosty morning.
It seems strange that as the earth get closer to the sun during its orbit then the amount of daylight that we get decrease. But that is the case. It is the tilt of the earth that determine the amount of daylight that we get and so the length of time that for us the sun is above the horizon.

How Day and Night Happen
The sun seems to rise in the morning, crosses the sky during the day and sets at night. However the sun does not actually move around the earth. Earth's turning on its axis makes it look as if the sun is moves.
The earth makes a complete turn on its axis for 24 hours. It is called as rotation. It causes day and night. The earth also moves around the sun. It takes 365 days or a year. This process is called revolution. The revolution process causes the changes of the season.


The term of “tsunami” comes from the Japanese which means harbour ("tsu") and wave ("nami"). A tsunamigk is a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale.

A tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Such large vertical movements of the earth's crust can occur at plate boundaries.

Subduction of earthquakes are particularly effective in generating tsunamis, and occur where denser oceanic plates slip under continental plates.

As the displaced water mass moves under the influence of gravity to regain its equilibrium, it radiates across the ocean like ripples on a pond.

Tsunami always bring great damage. Most of the damage is caused by the huge mass of water behind the initial wave front, as the height of the sea keeps rising fast and floods powerfully into the coastal area.
