Solar Eclipse And Lunar Eclipse

As we all know that both the Earth and the Moon get light, ie energy, from the Sun. Due to the same rotation speed of both the Earth and the Moon, only one part of the Moon is visible from the Earth.

When the Sun, the Moon and the Earth are in a straight line, then a solar eclipse or a lunar eclipse occurs. Total solar eclipses are often seen but total lunar eclipses are not often seen. There can be a maximum of seven eclipses (solar eclipse and lunar eclipse) in a year. Out of which solar eclipse can happen at least twice and maximum five times.

Full Moon ( पूर्णिमा )

When the entire illuminated part of the moon is visible from the earth, it is called a full moon. This phenomenon happens only once in a month. That is, on this day the entire illuminated part of the moon is in front of the earth.

New Moon ( अमावस्या  )

Unlike the full moon, when the entire unlit part of the moon is visible from the earth, it is called Amavasya. This phenomenon also happens only once in a month. That is, on this day the entire unlit part of the moon is in front of the earth.

1. Solar Eclipse : How and when?

In this state of solar eclipse, the Moon comes between the Sun and the Earth during the day, due to which the light of the Sun does not fall on the Earth, but the shadow of the Moon falls on the Earth. Solar eclipse takes place on Amavasya. Total solar eclipses are often seen but total lunar eclipses are not often seen.

Partial Solar Eclipse 

When the Moon covers only some part of the Sun, this situation is called Partial Solar Eclipse.

Diamond Ring

When the Moon covers the Sun completely, at that time only the peripheral part of the Sun shines like a diamond. This bright peripheral part of the Sun is called the diamond ring. This state is formed only at the time of total solar eclipse.

2. Lunar Eclipse : How and when?

In this state of lunar eclipse, the Earth comes between the Moon and the Sun, due to which the light of the Sun does not fall on the Moon, but the shadow of the Earth falls on the Moon. Lunar eclipse always happens on full moon night. Total solar eclipses are often seen but total lunar eclipses are not often seen.

Few Questions and Answers

  1. Question: According to the above description, there should be a lunar eclipse on every full moon and a solar eclipse on every new moon, but this does not happen. Why ?
    • Answer : The rotation speed and orbital path of the Moon and the Earth are the same, but the Moon is inclined to its axis by 5 degrees, due to which when the Moon and the Earth reach the same point of rotation, at that time the Moon moves a little further due to its axial tilt. goes For this reason, lunar eclipse and solar eclipse do not occur on every full moon and new moon.
  2. Question: Total solar eclipses are observed but total lunar eclipses are not observed, why?
    • Answer : Due to the substantial difference in the size of the Sun, Moon and Earth, total solar eclipses are observed, but total lunar eclipses are not observed.
  3. Question : Solar eclipse should not be seen with bare or naked eyes, why?
    • Answer : At the time of a solar eclipse, the Moon comes between the Sun and the Earth. In this state, ultraviolet rays emerge from the peripheral regions of the Sun, which are harmful to the eyes. During a total solar eclipse, a diamond ring is formed around the Sun. This emits a large amount of ultraviolet rays.

Fault – Endogenous Force

Fault – Endogenous Force The relief of our earth is full of variations and contrasts. Due to fault-endogenous force on the upper surface of the earth, some fault valley, ramp valley have been formed. Somewhere there are deep trenches, and somewhere there is sea. In some places there are snow-filled glaciers and mountain ranges, where there is no trace of vegetation, then there are also marshy places, which are full of oddities and mysteries. Have we ever thought, what is the reason for all these differences? The answer is –  Internal Structure Of The Earth  Mainly two types of forces work on the earth, which are as follows – Endogenous forces – By these, disparities are created on the earth. Like – Earthquake, Tsunami, Long term force etc. Exogenous Forces – These are the plane stabilizing forces of the earth. Like – flowing water, sea water, glacier, wind etc. Genetic Terminology - Genetics 1. Endogenous Force As we said above, inequalities are created on the earth by endoge...

Different Branches and Sub-Branches of Science and Their Fields of Study

Science Science is a very wide field. There are various branches and sub-branches of science. It is mainly divided into two parts Natural Science and Social Science. Natural Science is again divided into two parts Physical Science and Biological Science, which are further divided into various branches and sub-branches. While various subjects of Arts Group have been kept under Social Science. Indian Classical Dance Form Different Branches of Science and Their Fields of Study  Animal Science or Zoology - Zoology: Detailed study of different types of living and dead animals Botany - Study of different types of plants and their activities. Paleontology -  Palaeobiology or Palaeontology: Study of different types of fossils (animals or plants). Paleobotany – Palaeobotany: Study of plant fossils.

Bt Toxin

Bt Crop Containing Bt Toxin Gene Bt refers to Bacillus thuringiensis i.e. Bt crop contains the amount of toxin obtained from the above bacterium or rather Bt toxin is formed in these crops which is active only when the crop is eaten by insects. In this way, after eating the crop, this toxin becomes active by going into the intestine of the insect and the insect dies. Pongal : A South Indian Festival Now the question arises that how did this poison reach inside the plants. Bt bacteria store many toxin proteins inside their spores and this toxin protein is made by the Bt toxin gene present inside the bacterium, that is, this toxin is produced by the Bt toxin gene. By biotechnology, this toxin gene is isolated from the bacterium and put in the gene of crop plants, due to which this toxin starts forming inside the crop plants as well. Exogenous Forces - Weathering and Erosion When Bt toxin is in the cell of bacteria or crop plants, then it is in dormant state and at this time it is called...
