This in turn helps in interpreting the mode of formation and the depositional environment of sedimentary rocks.
Thus the discipline of geomorphology is fundamental to the uniformitarian approach to the Earth sciences according to which the present is the key to the past.

A wall painting in the tomb of Djehutihotep clearly shows a person standing on the front of the pulled sledge and pouring water over the sand just in front of it.
Geochemistry is the study of the composition of these different types of rocks.
During mountain building, rocks became highly deformed, and the primary objective of structural geology is to elucidate the mechanism of formation of the many types of structures (e.g., folds and faults) that arise from such deformation.
Source: Al-Ahram Weekly, 5-11 August 2004, issue 702.Geomorphology is concerned with the surface processes that create the landscapes of the world—namely, weathering and erosion.Weathering is the alteration and breakdown of rocks at the Earth’s surface caused by local atmospheric conditions, while erosion is the process by which the weathering products are removed by water, ice, and wind.They determined both the required pulling force and the stiffness of the sand as a function of the quantity of water in the sand.To determine the stiffness they used a rheometer, which shows how much force is needed to deform a certain volume of sand.
