Observe carefully the location of the sun, earth and moon in the given diagram and tell what it depicts (Sun ← Earth, with Moon positioned above Earth, indicating Earth is between Sun and Moon):

When the Earth is positioned between the Sun and the Moon (Sun—Earth—Moon alignment), a lunar eclipse occurs. The Earth's shadow falls on the Moon, blocking sunlight from reaching it. In contrast, a solar eclipse occurs when the Moon is between the Sun and Earth. Spring tides occur during full and new moons when Sun, Earth, and Moon are aligned, but the specific Sun-Earth-Moon (with Earth in middle) configuration here specifically depicts a lunar eclipse setup.
