These are cross-bedding, which is common in fluvial or eolian deposits, and graded bedding, which reflects transport by density (or turbidity) currents or, in certain cases, varved deposits. Second, layers can happen in sedimentary rock when layers of sediment are laid down and these layers of Earth are cemented together because of great pressure. Register free for online tutoring session to clear your doubts. Later, these form layers on top of each other. This division into more or less parallel layers is called stratification, and the extent to which the division is carried varies according to circumstances.

Stratification is also seen in Earth's atmosphere, where the layers of the atmosphere are arranged by density. Layers form in all three situations because of density. According to the law of superposition, the oldest fossils are found. Stratified rock is made of visible layers of sediment, while the lake contains a warm upper layer and a cold bottom layer. By the law of original horizontality, each layer is younger than all the layers beneath it. Our editors will review what youve submitted and determine whether to revise the article.
