What occurs when one celestial body obscures another?

Ebb Tide
Echo
Eclipse
Ecology

The correct answer is: Eclipse

When one celestial body obscures another, it is referred to as an eclipse. This phenomenon happens when the Earth, Moon, and Sun align in such a way that one body casts a shadow on another, blocking its light. For example, a solar eclipse occurs when the Moon passes between the Earth and the Sun, leading to a temporary darkening of the day. Conversely, a lunar eclipse occurs when the Earth comes between the Sun and the Moon, causing the Earth’s shadow to cover the Moon. The other options do not pertain to this specific astronomical event. An ebb tide relates to the flow of ocean water, echo refers to a sound reflection, and ecology is the study of organisms and their interactions with the environment. These terms pertain to different scientific concepts not associated with the obscuring of celestial bodies.
