5) What is true of geochemical cycles?
a) There is a variable amount of each element on Earth.
b) A reservoir is where elements remain through time.
c) Only external energy sources drive movement of elements.
d) Geochemical cycles are characterized by the movement of elements.
D
Geochemical cycles like carbon cycle, nitrogen cycles etc are pathways through which an element moves possessing several processes. Movement of elements is the primary character of all geochemical cycles
