FAQs on Eclipses Video Lecture - Science (Curiosity) Class 7 - New NCERT
| 1. What is an eclipse? |  |
Ans. An eclipse occurs when one celestial body moves into the shadow of another body, blocking the light from one to the other. There are two main types of eclipses: solar eclipses, where the Moon moves between the Earth and the Sun, and lunar eclipses, where the Earth comes between the Sun and the Moon.
| 2. How often do eclipses occur? | |
Ans. Eclipses occur several times a year, but not every eclipse is visible from every location on Earth. On average, there are about 2 to 5 solar and lunar eclipses each year, but total solar eclipses, which are visible from specific areas, are rarer.
| 3. What is the difference between a solar eclipse and a lunar eclipse? | |
Ans. A solar eclipse happens when the Moon passes between the Earth and the Sun, blocking the Sun's light either partially or totally. A lunar eclipse occurs when the Earth is positioned directly between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.
| 4. Can eclipses be predicted? | |
Ans. Yes, eclipses can be predicted with a high degree of accuracy. Astronomers use mathematical calculations based on the orbits of the Earth and Moon to determine when and where eclipses will happen, sometimes hundreds of years in advance.
| 5. Is it safe to look at an eclipse? | |
Ans. It is not safe to look directly at a solar eclipse without proper eye protection, such as eclipse glasses, because the Sun's rays can cause serious damage to your eyes. However, lunar eclipses are safe to view with the naked eye as they do not involve direct sunlight.
