Which of the following is true for all types of fronts (warm, cold , stationary, and occluded)?

Can't see any choices but isn't it something to do with different air masses "meeting" each other such as hot air and cold air, with maybe a spot of water vapour and a few winds thrown in for good stormy weather ?

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.
