The Large Reservoir of Sulphur on the Earth Surface: A Comprehensive Overview
Sulphur, a vital resource, is found in abundance in various facets of the earth. The largest repository of this essential element on the earth’s surface is nestled in the lithosphere and marine sediments. They form an immense base housing enormous amounts of sulphur, decidedly influencing the global sulphur cycle.
The earth’s core and mantle also hold an unspecified amount of sulphur, essentially cut off from the earth’s surface. Despite this isolation, it remains relevant due to its consistent involvement with the surface reservoir over extensive periods.

Interplay between the Surface and Core
In the long course of the earth’s history, the surface sulphur reservoir has been in constant contact with the mantle. This contact over a substantial period has affected the size of the surface reservoir and possibly, its isotopic composition. This interplay between the surface and the core makes the large reservoir of sulphur on the earth surface far more dynamic and critical than it initially appears.

Sulphur in the Ocean
Arguably one of the most significant reservoirs of sulphur on the earth surface is the ocean. It holds enormous quantities of sulphur, majorly in the form of dissolved sulphate and sedimentary minerals. This sulphur content contributes significantly to the overall reserves of sulphur on the earth’s surface.
Stability of Sulphate
Indeed, sulphate, found profusely in oceans, is the most stable form of sulphur on earth. The weathering and leaching of rocks and sediments primarily provide this sulphate to the ocean. The stability of sulphate makes it a prime component of the large reservoir of sulphur on the earth surface.
Influential Factors on Surface Reservoir
In addition to the ocean and lithosphere, there are other factors at play. The earth’s core and mantle, with their sequestered sulphur, impact the surface reservoir size. Over long time scales, the exchange between the mantle and the surface has influenced the surface reservoir’s size and possibly, its isotopic composition.
1. What is the primary reservoir of sulphur on earth’s surface?
The primary reservoirs of sulphur on earth’s surface are the lithosphere and marine sediments.
2. Is there any sulphur in the earth’s core and mantle?
Yes, the earth’s core and mantle contain an unspecified amount of sulphur, which is sequestered and hence, not part of the global sulphur cycle.
3. How does the ocean contribute to the sulphur content on earth’s surface?
The ocean holds large quantities of sulphur, mainly as dissolved sulphate and sedimentary minerals.
4. What is the most stable form of sulphur on earth?
Sulphate, found largely in the ocean, is the most stable form of sulphur on earth.
