Question

question 4: explain why no place on earth can see a total eclipse of the sun under these circumstances.

Explanation:

A total solar eclipse occurs when the Moon completely blocks the Sun as seen from Earth. If no place on Earth can see a total eclipse of the Sun under certain circumstances, it could be because the alignment of the Sun, Moon, and Earth is not perfect enough for the Moon's umbra (the region of total shadow) to reach the Earth's surface. The relative distances and positions of these celestial bodies determine whether the umbra intersects Earth. If it doesn't, no - one on Earth will experience a total solar eclipse.

Answer:

The alignment of the Sun, Moon, and Earth is such that the Moon's umbra does not reach the Earth's surface.
