True. Coastal regions are affected if it is warm currents over the ocean it make for a higher temperature over the land, if it's a colder current over the ocean it makes for temperatures to drop over land. This happens when the wind blows in from the sea.
The magnetic field is believed to be generated by electric currents in the conductive material of its core, created by convection currents due to heat escaping from the core. So your answer is A
Covalent bonds would be formed when a non-metal bonds with another non-metal
