Answer:
C. Rocks rich in calcium, potassium, and sodium, weather into fertile soil.
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Hence, the statement which is true is that, rocks rich in calcium, potassium, and sodium, weather into fertile soil because these nutrients (chemical elements) are responsible for determining the level of fertility of a soil.

The spheres interacting when a volcano erupts and releases gases into
the air can be described as the lithosphere and the atmosphere. The
lithosphere is the outer part of the earth, where volcanoes are located,
which is made up of the crust and mantle. The atmosphere can be
described as the gases surrounding the earth.
