Volcanoes are natural openings in the Earth’s surface that allow molten rock, gases, and ash to escape from beneath the crust. They form primarily at tectonic plate boundaries, where plates either collide, move apart, or slide past each other, creating pathways for magma to rise. Hotspots, areas of intense heat in the mantle, can also produce vol

Recycling is the process of converting waste materials into new products, reducing the need for raw resources and minimizing environmental impact.

Sound is a type of energy created by vibrations that travel through a medium, such as air, water, or solids, and can be detected by the human ear. The study of sound, or acoustics, examines how these vibrations produce waves, how they propagate, and how they are perceived. Factors like frequency, amplitude, and wavelength determine pitch, volume, a
