Which is the most abundant state of matter on earth ?
Show answer Hide answer
Answer: C. Solid
Explanation
Solids maintain fixed shapes and volumes due to strong intermolecular holding forces. The Earth's immense crust and mantle consist almost entirely of rocky solid matter. This geological composition makes the solid state the most abundant phase on Earth. States of matter on Earth include solids, liquids, gases, and high-energy plasma forms. Silicate minerals and metallic iron comprise the vast majority of the planet's internal mass. Solid matter exhibits high density compared to atmospheric gases and surface water oceans.
Geologists study solid mineral structures to understand the tectonic history of our planet. Civil engineering relies on the stability of solid geological foundations for construction. Mining industries extract valuable metals from solid mineral ores embedded in Earth's crust. Gas makes up the atmosphere, but Earth's mass is overwhelmingly composed of solid rock. Liquid forms vast oceans, but water covers only the surface layer above the solid mantle. Plasma is abundant in stars, but rare naturally on Earth outside of lightning discharges.
