Understanding Solar Eclipses

What makes solar eclipses possible on Earth?

• The moon orbits the Earth once a year.

• The sun and moon appear the same size in the sky due to their relative sizes and distances from Earth.

• The moon is 400 times larger than the sun.

• The Earth's shadow covers the moon.

Why are solar eclipses rare events at any given location on Earth?

• Because the Earth is moving away from the sun.

• Because solar eclipses happen every month.

• Because the moon's orbit is tilted relative to Earth's orbital plane.

• Because the moon is getting larger over time.

What is the path of totality?

• The area on Earth where the moon's shadow completely covers the sun during an eclipse.

• The trajectory of the Earth around the sun.

• The path the moon takes around the Earth.

• The orbit of the sun around the galaxy.

What historical figure came close to accurately predicting a solar eclipse?

• Isaac Newton

• Albert Einstein

• Edmund Halley

• Galileo Galilei

What is the significance of using eclipse glasses?

• To look more fashionable during the eclipse.

• To protect your eyes from harmful solar radiation during the eclipse.

• To see the eclipse in different colors.

• To magnify the view of the eclipse.

What are Baily's Beads?

• The name of a famous astronomer.

• The stars visible during a total solar eclipse.

• Bright spots of light that appear as the moon moves over the sun.

• A type of eclipse glasses.

What phenomenon creates the 'diamond ring' effect during a solar eclipse?

• The last bit of sunlight shining through the valleys on the moon's surface.

• The appearance of stars during totality.

• The appearance of solar flares.

• The full illumination of the moon.

What discovery was made during a solar eclipse in 1868?

• The structure of the sun's corona.

• The element helium.

• The first photograph of an eclipse.

• The existence of the asteroid belt.

What did the 1919 solar eclipse help to prove?

• The existence of black holes.

• The process of nuclear fusion in the sun.

• The theory of relativity.

• The discovery of helium.

Why won't we always have total solar eclipses on Earth?

• Because the Earth's orbit is changing.

• Because solar eclipses are a man-made phenomenon.

• Because the moon is slowly drifting farther from Earth.

• Because the sun is slowly moving away from Earth.
