During a solar eclipse, the umbra is the region where the Moon completely blocks the Sun, while the penumbra is where some sunlight can still be seen. True or False?

True. The umbra is the narrow cone of shadow where the Moon’s disk covers the entire Sun, so no direct sunlight reaches the ground. The penumbra is the outer, wider shadow where the Moon only partially covers the Sun, letting a crescent of light remain visible. During a total solar eclipse, observers in the umbra see a full black sky and a bright corona, while those in the penumbra see a brightened but still sunny sky. For example, when the eclipse path passes over a city, people inside the umbra watch the Sun vanish, while nearby towns in the penumbra still see a glowing sun.
