SBCC ERTH101 EXAM 3 Questions With 100% Correct Answers

Plasma - electrically charged gas Thermonuclear fusion - The transformation of lighter atomic particles into heavier ones, requiring high temperatures. Hydrostatic equilibrium - the condition in which gravity and gas pressure are balanced Differential rotation - Rotation of different regions of an object (different latitudes or depths) at different rates Core - the central region of a star where high temperatures and high densities allow thermonuclear fusion reactions to occur, releasing energy Radiative Zone - the region of the sun above the core, where energy is transported outward by means of electromagnetic radiation (photons scattering off of particles of mass) Convective Zone - The region of the sun above the radiative zone, where energy is transported outward by the means of the motion of gas Photosphere - the thin "surface" of the sun, from which radiation escapes into space Chromosphere - the lower layer of the suns atmosphere Corona - the extended region of the extremely hot, low density gas surrounding the sun Strong nuclear force - One of the four fundamental forces in nature, it binds particles together the nucleus of an atom Proton-proton (P-P) chain - the sequence of reactions required to convert hydrogen nuclei into helium nucleiAntimatter - A form of matter that annihilates on contact with normal matter. Particles and antiparticles of the same type have the same mass but opposite charge Positron - the antimatter version of the electron, having the mass of the electron but a positive charge
