Final answer:
Two events that must happen at the same time to cause a solar eclipse are: 1) The Sun, Earth, and Moon need to be on the same straight line, and 2) the Moon must be in the plane of the ecliptic.
Step-by-step explanation:
A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light and casting a shadow on Earth. This phenomenon can result in a total or partial obscuration of the Sun. Solar eclipses are rare events and can captivate observers with their celestial beauty.
A solar eclipse occurs when the Moon moves between the Sun and Earth, casting its shadow on a part of Earth's surface. For a solar eclipse to happen, two events must occur at the same time: (1) The Sun, Earth, and Moon need to be on the same straight line, and (2) the Moon must be in the plane of the ecliptic, which is the plane where the Sun and Earth are. When these conditions are met, a solar eclipse can take place.
