Ice Formation Process Glaciers form as snow accumulates and compresses over years, transforming into dense glacial ice. Each layer of snow compacts under its own weight, expelling air and creating a crystalline structure. This process, called firnification, gradually turns loose snow into solid ice. The weight of accumulated ice eventually cause

Classification by Height Clouds form at three main atmospheric levels. Low-level clouds (0-6,500 feet) include stratus and cumulus, often appearing dark and dense. Mid-level clouds (6,500-23,000 feet) like altocumulus and altostratus appear as gray or white sheets. High-level clouds (above 23,000 feet) such as cirrus consist mainly of ice crysta

Formation Process Desert sand dunes form when wind transports loose sand particles and deposits them in sheltered areas or where obstacles interrupt airflow. The process begins with saltation, where wind lifts sand grains that bounce along the surface, dislodging more particles. Dune shape depends on wind direction consistency, sand supply, and

Basic Light Properties Light travels as electromagnetic waves, with different wavelengths producing various colors visible to the human eye. The visible spectrum ranges from approximately 380 nanometers (violet) to 700 nanometers (red). White light contains all visible wavelengths, while objects appear colored by reflecting specific wavelengths
