Answer:
The movement of carbon from the atmosphere to the lithosphere ( rocks ) begins with rain. Atmospheric carbon combines with water to form a weak acid ( carbonic acid ) that falls to the surface in rain. The acid dissolves rocks - a process called chemical weathering and releases calcium, magnesium, potassium, or sodium ions.

-subtraction
Explanation:
Elevation is the altitude of a place above a reference frame.
To find the difference between the elevation between two or places on a map, we perform a subtraction operation.
The differences in elevation is the subtraction of the two elevation values from one another.
For example if point A on a map is at 60m above sea level and point B is at 100m, the change in elevation is;
Change in elevation = Elevation of B - Elevation of A = 100m - 60m = 40m
A spit could form from a rocky headland where prevailing winds would blow at an angle to the rocky headland, gradually depositing sand and shingle at that place.
A spit is a permanent landform resulting from marine deposition and wind deposition. It is usually a long and narrow accumulation of sand or shingle with one joined to the land and the other end projecting at a narrow angle out into the sea.
Salt marshes sometimes form on the sheltered side of a spit.
