What is oxide capacitance?

It is the ratio of e permittivity of the silicon dioxide which is 3.45×10^-11 F/m and thickness of the oxide. It is much more convenient to express Cox per micron squared.

Explain the whole process of the channel region of the MOSFET forming a parallel-plate capacitor.

The gate and the channel region of the MOSFET form a parallel-plate capacitor, with the oxide layer acting as the capacitor dielectric. The positive gate voltage causes a positive charge to accumulate on the top plate of the capacitor (the gate electrode). The corresponding negative charge on the bottom plate is formed by the electrons in the induced channel. An electric field thus develops in the vertical direction. It is this field that controls the amount of charge in the channel, and thus it determines the channel conductivity and, in turn, the current that will flow through the channel when a voltage is applied.
