Psychology

Psychology is an academic and practical field relating the scientific study of mental procedures and conduct. Psychology as well refers to the application of such knowledge to a variety of spheres of human action, with troubles of persons' daily lives and the treatment of mental illness.

Psychology varies from the other social sciences — anthropology, economics, political science, and sociology — in looking for to make clear the mental procedures and conduct of individuals. Psychology differs from biology and neuroscience in that it is mainly concerned with the communication of mental procedures and actions on an entire level, as opposed to learning the biological or neural procedures themselves. Biological psychology is the scientific learning of the biological basis of conduct and mental conditions.

Convection zone

Structure of the SunFrom about 0.7 solar radii to the Sun's visible surface, the material in the Sun is not dense enough or hot enough to transfer the heat energy of the interior outward via radiation. As a result, thermal convection occurs as thermal columns carry hot material to the surface (photosphere) of the Sun. Once the material cools off at the surface, it plunges back downward to the base of the convection zone, to receive more heat from the top of the radiative zone. Convective overshoot is thought to occur at the base of the convection zone, carrying turbulent downflows into the outer layers of the radiative zone.

The thermal columns in the convection zone form an imprint on the surface of the Sun, in the form of the solar granulation and supergranulation. The turbulent convection of this outer part of the solar interior gives rise to a "small-scale" dynamo that produces magnetic north and south poles all over the surface of the Sun.
