 Solar and Lunar Eclipse

 

Solar and Lunar Eclipse- Science What is an eclipse? The earth revolves around the sun and the moon revolves around the earth. During revolutions sometimes the Sun, the Earth and the Moon come in a straight line. The light from the Sun is obstructed by the Earth or the Moon. As a result the shadow is formed. Such phenomenon is known as eclipse. There are two kinds of eclipse - Lunar Eclipse and Solar Eclipse. First we will learn the concept of solar eclipse. The earth moves in an elliptical path around the sun. The moon revolves around the Earth in an almost perfectly circular path but is inclined about 5 degrees. During revolution when the moon comes between the Earth and the Sun, the source of light from the sun is partially or completely blocked. When the Moon and the Sun are in a perfect line, the shadow of the moon fall on the Earth. This phenomenon is called a total solar eclipse. When the Moon comes between the Sun and the Earth, but they don't align in a perfectly straight line, the Moon only partially covers the Sun. This is known as partial solar eclipse. The solar eclipse is rare phenomenon. It rarely happens the Sun, the moon and the earth comes in a straight line, because the moon revolves around the Earth in an elliptical path which is inclined at an angle of 5 degrees. Now let us learn the concept of Lunar Eclipse During revolution when the Earth comes between the Sun and the moon, the Earth blocks part of the Sun's light from reaching the moon. During a lunar eclipse, the shadow of the Earth falls on the moon and the view of the moon gets blocked. The moon appears reddish in colour during total lunar eclipse. A partial lunar eclipse happens when the Earth moves between the Sun and the Moon, but they are not completely aligned. It occurs when a small part of the Moon's surface is covered by the central part of the Earth's shadow.
