Understanding Lunar Eclipses

The video explains lunar eclipses, which occur when the Earth casts a shadow on the moon, blocking sunlight. It covers historical beliefs, the mechanism behind eclipses, and the types of eclipses: total and partial. The video also explains why lunar eclipses don't happen every full moon due to the moon's tilted orbit. During a total eclipse, the moon appears red due to sunlight bending through Earth's atmosphere.

What did the Incas believe caused a lunar eclipse?

• A giant jaguar ate the moon

• The moon fell into the ocean

• The moon turned into a star

• The sun blocked the moon

What is the meaning of the word 'eclipse' in Greek?

• To leave

• To appear

• To shine

• To hide

What is the primary reason we can see the moon?

• It generates its own light

• It reflects sunlight

• It glows due to Earth's atmosphere

• It absorbs light from stars

During a total lunar eclipse, why does the moon appear reddish-orange?

• Sunlight bends through Earth's atmosphere

• Earth's shadow is red

• The moon's surface changes color

• The moon is closer to the sun

What happens during a partial lunar eclipse?

• The moon is completely covered by Earth's shadow

• The moon is partially covered by Earth's shadow

• The moon disappears completely

• The moon becomes invisible

What is the main difference between total and partial lunar eclipses?

• Partial eclipses make the moon disappear

• Total eclipses occur during the day

• Partial eclipses are visible only from space

• Total eclipses cover the moon completely with Earth's shadow

What role does Earth's atmosphere play during a total lunar eclipse?

• It causes the moon to glow blue

• It bends sunlight, allowing some to reach the moon

• It makes the moon invisible

• It blocks all sunlight from reaching the moon

Why don't lunar eclipses occur every full moon?

• The moon's orbit is tilted relative to Earth's orbit

• Earth's shadow is too small

• The sun is not always aligned with the moon

• The moon is too far away

What must align for a total lunar eclipse to occur?

• The sun, Earth, and moon must be in a straight line

• The moon must be at its highest point in the sky

• The moon must be closest to Earth

• The sun must be directly above the moon

What is required for a lunar eclipse to be visible from Earth?

• The moon must be new

• The moon must be full

• The moon must be half

• The moon must be crescent
