Explanation

An eclipse occurs when one celestial body moves into the shadow of another. A lunar eclipse takes place when the Earth comes directly between the Sun and the Moon, causing the Earth's shadow to fall on the Moon [c2][t6]. This phenomenon can only occur during a full moon phase [c1][c5]. Conversely, a solar eclipse happens when the Moon comes directly between the Sun and the Earth, casting the Moon's shadow onto the Earth's surface [t1][t5]. This alignment occurs only during a new moon phase [c1][t5]. Statements 3 and 4 are incorrect because the Sun never comes between the Earth and the Moon, and the Earth being between the Sun and Moon defines a lunar, not solar, eclipse. Therefore, only statements 1 and 2 are scientifically accurate descriptions of these astronomical alignments [t4][t6].
