In a conventional oven it's mostly conduction,
with a bit of air convection thrown in.
There are "ovens" (as seen on TV ... mostly at 3AM) that use hot air and forced convection as the main heat transfer technique.
It is electrical or chemical energy into thermal energy.

Either a reduction of the ambient pressure or an increase in thermal energy (temperature).

Heat is a transfer of thermal energy.
There is no particular difference between heat and thermal energy. Heat is a form of thermal energy. Since thermal energy is energy from heat, heat and thermal energy are basically the same thing.
Most things have thermal energy. Thermal energy is comes from heat and therefore anything that can generate heat has thermal energy. All living things have thermal energy.
Either a reduction of the ambient pressure or an increase in thermal energy (temperature).
Thermal energy is the energy store within the bonds of atoms. It is heat.
The two types of thermal energy sources are Geothermal and Thermal Energy
