Overview
Sedimentary structures are essential features in geology that provide valuable information about the conditions under which sediments were deposited. They include various forms such as stratification, ripple marks, and mud cracks, each indicating different environmental conditions. Understanding the...
Key Terms
Example: Stratification can be seen in river deposits.
Example: Ripple marks indicate the direction of water flow.
Example: Mud cracks are common in arid environments.
Example: Worms burrowing through sediment cause bioturbation.
Example: Rivers, lakes, and oceans are different depositional environments.
Example: Sand and silt are types of sediment.
