The meniscus of mercury in a glass capillary tube is convex because of the very high density of mercury as compared with water the low surface tension of mercury the greater attraction of mercury atoms to the glass than to each other the weaker attraction of mercury atoms to the glass than to each other electrostatic repulsion between the glass and the mercury

Yup no bull frogs here man

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
