Understanding these processes is essential for interpreting Earth history, management in natural hazards, and locating economic deposits such aparendwater aquirs, petrolem incirs, and miners.

Types of Sedimentary Processes

Te sedimentary cycle can be divided into five main stages: weathering, erosion, transport, deposition, and lithification. Although presented sequentially, these processes often overlap and d interact in complex ways across different different distal and temporal scales.

Transport

Wind transports sediment as bedload (salting sand grains) or suspended load (fine dutt). Sand dunes form where wind velocity drops, such as behind obstacles or in topographic lows. Duszt can travel thinkands of kilometers, as seen wheren Saharan duss navuzes the Amazon raindept.
