Understanding Solar Eclipses

What causes a solar eclipse?

• The sun moves behind the Earth, causing darkness.

• The sun and moon switch places in the sky.

• The moon passes between the Earth and the sun, blocking the sun's rays.

• The Earth passes between the sun and the moon, casting a shadow on the moon.

Why do the sun and the moon appear to be the same size in the sky?

• Because the sun is 400 times wider than the moon but also 400 times farther away.

• Because the sun and moon are actually the same size.

• Because the moon is much larger than previously thought.

• Because the sun is much closer to the Earth than the moon.

What is the path of totality?

• The imaginary line created by the moon's umbral shadow across Earth.

• The trajectory of the sun during an eclipse.

• The area on Earth where a partial eclipse can be seen.

• The path the moon takes around the Earth.

How can you safely watch a solar eclipse?

• Looking directly at the sun.

• Using regular sunglasses.

• Using certified eclipse-watching glasses.

• With a telescope.

Why will we not always be able to see total solar eclipses?

• Because solar eclipses are becoming less frequent.

• Because the sun is getting smaller.

• Because the Earth is moving away from the sun.

• Because the moon is moving away from the Earth.
