A solar eclipse occurs when the Moon passes directly between the Earth and the Sun, blocking the Sun's light either partially or completely. For a total solar eclipse to happen, the Sun, Moon, and Earth must be aligned in a straight line, with the Moon in the new moon phase. This alignment typically occurs about two to five times a year, but total eclipses are less frequent at any given location on Earth.

Convection is utilized in everyday life through various means, such as cooking and heating. For instance, when boiling water, heat from the stove warms the pot, causing the water at the bottom to rise and cooler water to sink, creating a circulation that evenly heats the entire pot. Similarly, in homes, convection currents help distribute warm air from heaters or cool air from air conditioners, maintaining a comfortable temperature throughout the space. Additionally, convection ovens use this principle to cook food evenly by circulating hot air around it.

A corner on a 3D shape is called a "vertex." In geometry, a vertex is a point where two or more edges meet. For example, a cube has eight vertices.
