Answer:
cross bedding
Step-by-step explanation:
Cross bedding is a sedimentary structure commonly found in wind-blown sandstones. It refers to inclined layers or sets of layers within the rock that are deposited at an angle to the main bedding plane. These inclined layers are formed as wind transports and deposits sediment in a specific direction, creating distinct cross-cutting patterns in the rock. Cross bedding is indicative of ancient sand dunes and provides valuable information about the direction of wind or water currents during the time of sediment deposition. It is an important feature used by geologists to understand the geological history and environmental conditions of an area.
