The correct option is this: ENERGY IS EMITTED.

An atom, which is in an excited state is an atom that has moved away from the ground level as a result of gaining energy. This type of atom has more energy compare to those in the ground state and it is also unstable. To return to the ground state, the atom has to emit the energy which it gained in the first instance. Thus, when an excited atom returns to the ground state, energy is always emitted.

lana66690 [7]

changes in density

Explanation:

The global thermohaline (conveyor belt) circulation is caused by changes in global ocean density.

The ocean water density is determined by the temperature and salt content of the ocean (thermo - heat and haline - salt).

  • Surface current drives warm and less water away for the equator towards the poles.
  • At the poles they become cold  and very dense sinking to the bottom and moving towards the equator back.
  • It is also called the ocean conveyor belt
