Picture 1 depicts convergent boundary.
Picture 2 depicts divergent boundary.
Picture 3 depicts transform boundary.
<h3>What is a Divergent boundary?</h3>
This occurs when two tectonic plates move away from each other while convergent boundary occurs when the plates collide with each other.
Transform boundary is a fault along a plate boundary where the motion is mostly horizontal.

Answer:
A diving regulator is a pressure regulator that reduces the pressure of gas in the tank and deliver it to the diver so that he/she can breathe easily. It must pass the controlled laboratory testing and must have a second adjustment knob to ensure ease of breathing. Modern regulators are precision made and designed to work under demanding conditions. 1st stage and 2nd stage, diaphragm and piston, exhaust valve and purge button are types of diving regulators.
