Which of the following is NOT involved in recording climate data?
A. Investigating air bubbles trapped in ice cores.
B. Analyzing species of pollen.
C. Identifying phosphorus levels in fossils.
D. Studying tree rings.

B

Explanation:

Air bubbles in glaciers (i believe) contain certain gases, which can be used to identify the climate of the time it was frozen. Scientists use the phosporus levels in fossils to identify the climate, as well as a trees' rings, since trees gain more as the years go by

hope this helps

for points guys

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
