Deposits of old alluvium are commonly referred to as "terraces." These terraces are formed by the accumulation of sediments in river valleys over time, where the river has cut down into its own floodplain. As the river changes course or lowers its base level, older alluvial deposits can become elevated and remain as distinct landforms.

What is the difference between old alluvium and new alluvium?
Alluvium refers to clay, silt, sand, gravel, or similar detrital material deposited by running water. New alluvium are these sediments that are being deposited right now and older alluvium refers to sediments that were deposited a short while before the new alluvium. For example, a 500 years ago some sediments were deposited in a stream bed and last year more sediments were deposited in that same stream bed. The 500 year old sediment would be older alluvium and the 1 year old sediment would be the younger alluvium.

What refers to sediments deposited from streams?

Why deltaic alluvium is more fertile than coastal alluvium?
Deltaic alluvium is more fertile than coastal alluvium because it tends to be rich in nutrients and organic matter brought down by rivers from distant regions. As the river water slows down upon reaching the delta, it deposits these nutrient-rich sediments, providing a fertile environment for plant growth. In contrast, coastal alluvium may have lower fertility due to higher levels of salt and other minerals that can inhibit plant growth.
Where can be alluvial soil found in India?
