Final answer:
The terms 'umbra' and 'penumbra' refer to the darkest and lighter shadows during an eclipse, respectively. An 'eclipse' means to vanish, while 'corona' is the visible ring of light during an annular solar eclipse.
Step-by-step explanation:
To match the words with the correct definitions for the phenomena related to solar and lunar eclipses, we can use the provided descriptions. Here's how each term matches with the given definitions:
- Umbra: the inner, darkest, cone-shaped shadow (4)
- Penumbra: The outer, larger, lighter shadow (1)
- Eclipse: to vanish (3)
- Corona: During a solar eclipse, the moon covers the sun, a small ring of fire is visible around the edge (2)
It's important to note that during a total solar eclipse, viewers within the umbra will witness the Sun completely hidden by the Moon. Those in the penumbra will experience a partial solar eclipse. Additionally, if the Moon is far enough away that it does not completely cover the Sun's disk, an annular eclipse occurs, characterized by a bright ring—often referred to as the 'ring of fire'—that is the corona visible around the Moon's silhouette.
