(a current in a fluid that results from convection.)

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.

3. Inheritance of acquired characteristics are the characteristic acquird by the ancestors and transmitted that gradually acquired characteristic to their progeny. Hence, the rats acquire the charactieristics and transfered it to the next generations.

4. Catastrophism means the regular occurrence of meteorological and geological disturbances to explain the existence the fossil record. Hence, teh mass exticiton due to asteroid impact is an example of Catastrophism.

So, the correct options in sequential order is natural selection, uniformitarianism, inheritance of acquired characteristics, and catastrophism.
