An obscuring of the light from one celestial body by the passage of another between it and the observer is called:
An eclipse occurs when one celestial body blocks the light of another.
When one heavenly body moves into the shadow of another heavenly body, it is called:
An eclipse happens when one body passes into the shadow of another.
How many types of eclipses occur on Earth?
There are two main eclipses on Earth: solar and lunar.
The first type of eclipse is:
The first type of eclipse is the lunar eclipse when Earth’s shadow falls on the Moon.
The second type of eclipse is:
The second type of eclipse is solar eclipse as the first type is lunar eclipse.
When Earth blocks the sunlight and casts its shadow on the Moon, it is called:
A lunar eclipse happens when Earth comes between the Sun and the Moon, blocking sunlight.
A lunar eclipse occurs only when there is:
Lunar eclipses occur during a full moon because the Earth, Sun, and Moon align.
Why does a lunar eclipse not happen on every full moon?
Because the Moon’s orbit is tilted about 5° to Earth’s orbit, eclipses don’t occur every full moon.
The shadow of Earth cast on the Moon, making it lose sunlight, is called:
In a lunar eclipse, the Moon moves into Earth’s shadow and loses direct sunlight.
A lunar eclipse occurs when:
The Earth must be positioned between the Sun and Moon for a lunar eclipse to occur.
The darkest part of Earth’s shadow, where light is completely blocked, is called:
Umbra is the darkest region of the shadow where no sunlight reaches.
The lighter outer part of Earth’s shadow, where light is partially blocked, is called:
Penumbra is the faint shadow around the umbra where sunlight is only partially blocked.
How many types of lunar eclipses are there?
There are three types of lunar eclipses: penumbral, partial, and total.
When the Moon only passes through Earth’s penumbra, it is called:
A penumbral lunar eclipse occurs when the Moon moves only through Earth’s penumbra.
When part of the Moon passes through Earth’s umbra, it is called:
A partial lunar eclipse occurs when only a portion of the Moon enters the umbra.
When the entire Moon passes through Earth’s umbra, it is called:
A total lunar eclipse happens when the whole Moon moves into Earth’s umbral shadow.
When the Moon comes between the Earth and the Sun, blocking sunlight fully or partly, it is called:
A solar eclipse happens when the Moon blocks sunlight reaching Earth.
During a solar eclipse, the Moon casts a shadow on Earth, consisting of:
The Moon’s shadow on Earth has two parts—umbra (dark) and penumbra (light).
The darkest part of the Moon’s shadow, where the Sun is completely blocked, is:
Umbra is the region where the Sun is totally hidden during a solar eclipse.
The lighter part of the Moon’s shadow, where the Sun is partly blocked, is:
Penumbra is the faint shadow where the Sun is only partially blocked.
