When pressure is put on the sides of a plate, an earthquake might form!

Yes. Decompression melting occurs at divergent plate boundaries as pressure on the mantle material decreases due to the withdrawal of oceanic crust at spreading centers.
Because it relies on the back pressure through a known orifice which its differential pressure across the plate relates to flow.
An orifice plate is a plat eused to measure flow. Pressure sensors are placed upstream and downstream of the the plate and hepressure differential is used with Bernoullis Equation t compute flow (including some experimental factors). A retriction plate is similar to an orifice plate but is much thicker. It is used to drop pressure upstream of a system. The convergence, throttlnig through thick section and divergece works the fluid and reduces total energy (transformed in firction, heat etc). This leads to an overall pressure reduction.
A restriction orifice (RO) is used to limit the flow through the pipe to a set flow by choking the flow at its sonic velocity. A flow orifice (FO) is usually used to determine the flow through the pipe from the pressure drop over the plate. There a normally two pressure taps (one on each side of the plate) and a pressure transmitter which determines the pressure drop over the plate. A formula is then used to convert this pressure drop to a flowrate for the specific fluid passing through the orifice. A FO usually has a temperature element to determine the gas temperature for use is the formula.
the orifice plate creates a restriction in the pipeline which creates a pressure drop across the plate. commonly found in high pressure relief systems or drain points (as this would usually be a HP/LP interface) and can also be used to measure flow, by measuring the pressure drop across the plate.
The phrase Orifice Plate is actually a device that measures either volume or mass flow rate. An Orifice Plate is a thin plate like device that has a hole in the middle.
Bleed or Weep Holes are located at the elevational top or bottom of the Orifice Plate. The Weep Hole is tangent to a circle equal to 98% of the line I.D. DRAIN HOLES are located at the bottom of the Orifice Plate to prevent liquids in a gas or condensate in a steam flow from damming up behind the Orifice Plate. VENT HOLES are located at the top of the Orifice Plate to allow gases in a liquid flow to vent pass the Orifice Plate.

An orifice flow meter is one of the simplest forms of flow meters. It is just a flat piece of metal installed in a pipe between flanges with a specific sized hole bored in the middle used to create pressure that can be detected by pressure taps on either side of the plate.
generally vena contracta is formed at distance of d/2 from orifice where d is diameter of orifice.
