Solar Eclipse:
Solar Eclipse occurs when the moon comes in between the sun and the earth. As a result, the moon blocks the light of the sun from reaching the earth’s surface and casts a shadow on it. This occurs on a new moon phase. Depending on the distance of the moon from the earth during the event, different types of solar concealment can be observed. They can be categorized as:
Partial: When the moon does not align completely with the sun and so only a portion of the sunlight is blocked from reaching earth.
Annular: When the moon covers the sun but the sun can be seen around the edges of the moon giving an impression of the sun is a bright ring surrounding the dark disc of the moon.
Total: When the sun is completely covered by the moon. The sky becomes so dark that it appears to be night. Only a small area on the earth can witness it.
Lunar Eclipse:
Also known as the eclipse of the moon, it occurs when the earth comes in between the sun and the moon. As a result, the earth blocks the light of the sun from reaching the moon’s surface and casts its shadow on the moon. It occurs on a full moon day. We can observe up to 3 lunar eclipses per year.Depending on how the sun, the moon, and the earth line up, lunar eclipse too can be categorized as:
Partial: When only a part of the moon moves into the shadow of the earth.
Total: When the earth passes directly in front of the moon and casts its shadow on the full moon.

It rains because there is a low pressure passing. Frontal lows have usually a warm front passing first. That is associated with very moist and saturated air masses; haze, drizzle, then lower clouds and steady rain.
But after that, comes often a cold front. Because now cold air comes from under, the air masses are very unstable and the weather more turbulent. That cold and dry air makes the visibility much better....

Hybridization happens when atomic orbitals mix to form a new atomic orbital. The new orbital can hold the same total number of electrons as the old ones. The properties and energy of the new, hybridized orbital are an 'average' of the original unhybridized orbitals.
The concept of hybridization was introduced because it was the best explanation for the fact that all the C - H bonds in molecules like methane are identical.
