The greenhouse effect is a natural process that helps regulate the Earth's temperature, making it suitable for life. It occurs when certain gases in Earth's atmosphere, such as carbon dioxide (CO2), methane (CH4), and water vapor, trap heat from the Sun. These gases allow sunlight to enter the atmosphere, but they prevent some of the heat from esca
A water molecule, represented by the chemical formula H₂O, consists of two hydrogen atoms bonded to one oxygen atom. The oxygen atom has a slight negative charge, while the hydrogen atoms carry a slight positive charge, creating a polar molecule. This polarity is what gives water its unique properties, such as its ability to dissolve many substan
The Moon goes through eight distinct phases during its approximately 29.5-day lunar cycle. These phases result from the relative positions of the Moon, Earth, and Sun. The cycle begins with the new moon, when the Moon is positioned between the Earth and the Sun, making it invisible from Earth. As the Moon orbits Earth, more of its sunlit side becom
The internet is a global network that connects millions of computers, servers, and other devices, enabling them to communicate and share information. It was initially developed as a way for government and academic institutions to share research, but it has since evolved into an essential tool for communication, commerce, education, entertainment, a
