Answer 2

Answer:

basic rock noun, pl. basic rocks;ecology term,Substrate term– (1) mineralogical: a rock with a low content of acidic minerals, i. e., containing only small amounts or entirely lacking SiO2 (2) chemical a rock with a high pH. Note: an ambiguous term; sometimes imprecisely used to refer only to the pH of a rock substrate; the mineralogical definition should be preferred because it includes the chemical composition of a rock; if the pH reaction needs to be emphasized it should be referred to as "a rock with a high pH" not as a "basic rock"; the two definitions are often not identical, ex , the mineralogy of a basalt is basic because it has a low content of SiO2-minerals
