It is well known terrain influences climate conditions, and erosive processes slowly but surely modify terrain along with tectonic causes, but all encompassing studies have been lacking on a global scale to understand how these 63:
Terrigenous sediments are responsible for a significant amount of the salt in today's oceans. Over time rivers continue to carry minerals to the ocean but when water evaporates, it leaves the minerals behind. Since chlorine and sodium are not consumed by biological processes, these two elements

Wind born sediment also transports billions of tons annually, most prominent in 306: 280: 60:
Sources of terrigenous sediments include volcanoes, weathering of rocks, wind-blown dust, grinding by glaciers, and sediment carried by rivers or icebergs.
