TERMINOLOGY FOR STRATIFICATION AND CROSS-STRATIFICATION IN SEDIMENTARY ROCKS, 16.1: Stratification and Cross Stratification. Q. Sedimentary rock, also called stratified rock, is formed over time by wind, rain and glacial formations. Stratification, the layering that occurs in most sedimentary rocks and in those igneous rocks formed at the Earth's surface, as from lava flows and volcanic fragmental deposits. During the formation of sedimentary rocks the sediments are deposited in waterbodies and get sorted out according to their size. This sedimentary rock has many layers. Soils can also be stratified into various horizons (which is really just another term for layers), ice cores can show stratification patterns, and even the atmosphere that surrounds Earth is stratified. Stratification in volcanic rocks and sedimentary rocks differs in certain respects. Necessary cookies are absolutely essential for the website to function properly.
