HYPOTHESIZE: WHAT CAUSES LUNAR & SOLAR ECLIPSES?

Anatomy of a Lunar Eclipse Umbra – Long, narrow area of total shadow Penumbra – Broader area of partial shadow surrounding umbra

Lunar Eclipses Earth casts a shadow on moon preventing sunlight from reaching it (MOON IS ECLIPSED)

Total lunar eclipse occurs when moon is fully in Earth’s umbra – Occurs only during full moon Partial Lunar Eclipse – Only a portion of moon in Earth’s umbra
