Eclipses starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Eclipses.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe the alignment of the Sun, Earth, and Moon during a lunar eclipse.
Describe the difference between a partial and a total solar eclipse.
Describe the role of the ecliptic in the occurrence of eclipses.
During a penumbral lunar eclipse, the Moon passes through which part of Earth's shadow?
During a total lunar eclipse, what color does the Moon typically appear and why?
Explain why it is dangerous to look directly at a solar eclipse without proper eye protection.
If the diameter of the Moon is 3,474 km and its distance from Earth during a total solar eclipse is 384,400 km, calculate its angular diameter in arcminutes. (Use the formula: angular diameter (radians) = diameter/distance, then convert to arcminutes.)
If the Earth's shadow at the distance of the Moon is about 9,200 km in diameter, and the Moon's diameter is 3,474 km, will the Moon fit entirely within Earth's umbra during a total lunar eclipse?
Which of the following best describes a solar eclipse?
(1) The Moon passes between the Earth and the Sun
(2) The Earth passes between the Sun and the Moon
(3) The Sun passes between the Earth and the Moon
(4) The Moon passes behind the Earth
Which of the following best describes the frequency of total solar eclipses at a given location on Earth?
(1) Once every year
(2) Once every 18 years
(3) Once every 360 years
(4) Once every 1000 years
Which of the following best explains why annular eclipses occur?
(1) The Moon is at perigee
(2) The Moon is at apogee
(3) The Earth is at perihelion
(4) The Earth is at aphelion
Which of the following is necessary for a total lunar eclipse to occur?
(1) The Moon must be in the Earth's umbra
(2) The Moon must be in the Earth's penumbra
(3) The Moon must be at perigee
(4) The Moon must be at apogee
Fill in the blank: The darkest part of the shadow during an eclipse is called the _______.
Fill in the blank: The line where the plane of the Moon's orbit crosses the plane of Earth's orbit is called the _______.
Fill in the blank: The path on Earth's surface where a total solar eclipse is visible is called the _______.
The region of partial shadow during an eclipse is called the _______.
True or False: A lunar eclipse can only occur during a full moon.
True or False: A partial solar eclipse is visible from a larger area on Earth than a total solar eclipse.
True or False: Eclipses can only occur when the Sun is near one of the nodes of the Moon's orbit.
True or False: The duration of a total solar eclipse at any given location can last up to 2 hours.
