What determines the properties of a mineral? a. the size of the specimen and the arrangement of its atoms b. the size and shape of a specific sample. c. the elements that compose it and its age. d. the elements that compose it and the arrangement of its atoms

The properties of a mineral are determined by the "elements that compose it and the arrangement of its atoms".

Explanation:

Every mineral possesses its own unique "physical and chemical properties". To determine these properties, a small sample of the mineral is collected from a naturally occurring deposit of the mineral. The size of this sample collected has nothing to do with the physical and chemical properties of the mineral. The elements that form the mineral and the size of atoms of these minerals is what ultimately matters in the determination of the properties of the given mineral.

Air pollution: “combustion results in gases such as nitrogen oxides, nitrogen dioxide and particulates. the main causes of air pollution include transport, domestic combustion and industrial processes. pollutants from these sources can cause problems in the immediate vicinity and a distance away.”

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
