Yes, SiO2 is used for isolation and it can be grown easily when compared to other materials. The process is also simple as it only required oxidation of the already existing Si layer

MOSFET is an acronym standing for Metal Oxide Semiconductor Field Effect Transistor.

MOSFET has high input impedance and offer input signal isolation from the circuit
Since the logic operations of depletion MOSFET is the opposite to the enhancement MOSFET, the depletion MOSFET produces positive logic circuits, such as, buffer, AND, and OR. The most significant advantage of the positive logic circuits is that it can produce positive feedback easily so that a single depletion MOSFET can become a memory cell. In contrast, you will need at least two enhancement MOSFET transistor to produce the positive feedback to build a memory cell. The other advantages of depletion MOSFET are that it is free from sub-threshold leakage current and gate-oxide leakage current. Since there is always a potential difference of Vdd between the gate terminal and channel for an enhancement MOSFET to cause the gate-oxide leakage current, the gate oxide leakage current is unavoidable when the transistor shrinks in size and oxide layer becomes thinner. The depletion MOSFET does not have this problem because there is no potential difference between the gate and channel. As a enhancement MOSFET shrinking in size, there is no way to stop the subthreshold leakage current diffused across from source to drain because the drain and source terminals are closer physically. This is not a problem for depletion MOSFET because a pinched channel will stop the diffusion current completely. The depletion MOSFET is the ideal, perfect transistor. The only disadvantage of depletion MOSFET is its inability to produce negative logic operations.
The SiO2 layer acts as an insulator and also it provides high input impedance to the MOSFET. This insulation is needed so that a circuit with high EMI or loads which generate back emf (motors) can be driven by applying gate current from a common circuit.

It depends. A depletion MOSFET can be used as an ehancemnet MOSFET when it is operated as an analog amplifier. However, a depletion MOSFET can't replace an enhancement MOSFET when it is operated as a digital switch. When a depletion MOSFET is used as a digital switch, since the junction between source terminal and substrate must be reverse biased, the voltage of the source terminal of an N typde transistor must be tied to Vdd, and it is completely opposite to an enhancement MOSFET. When a depletion MOSFET is used as an analog amplifer, the source terminal and the substrate are both at the same potential, just like an enhancement MOSFET.

Of course it is possible to make an inverter with a p-MOSFET!
Use a mosfet driver instead of a simple resistor. Using a resistor to control the mosfet is a bad idea anyways because you will have terrible control (mosfets are voltage controlled. Take a look at the response curve for your mosfet). If your mosfet is fully on, its ratings may be too low for continuous operation or the power dissipation is too low for the transition between off an on an that is killing your mosfet.
