It can be either.
You can keep a balloon from rising or falling by adjusting its internal pressure to match the external air pressure. If the internal pressure is the same as the external air pressure, the balloon will stay at the same altitude. Additionally, you can attach a weight to the balloon to counteract its natural tendency to rise.
Pressure is the force applied over a specific area, while stress is the internal force created within a material in response to an applied load. Pressure is usually external and uniform, while stress is internal and can vary depending on the material's properties.
External pressure is the force exerted by the surroundings on a system. It can affect the behavior and properties of the system, such as in chemical reactions or phase changes. External pressure can influence the equilibrium position of reactions and the physical state of substances.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
External forces act on an object from outside its system, while internal forces arise from interactions within the system itself. External forces can change the state of motion of an object, while internal forces contribute to the object's stability, structure, and internal interactions. The overall behavior of an object is determined by the net effect of both external and internal forces acting upon it.

The possible internal and external influences on your food choices include; External: advertising peer pressure aroma ease of access Internal: general hunger perceived deficiency (yearning for a particular food or flavor)
Is a salmon internal or external?
In the sea, the external water pressure is greater than the ear's internal air pressure, so it implodes. In space, the external vacuum is less pressure than the ear's internal air pressure, so it explodes (or is 'sucked' into space.)
Our bodies have an internal pressure equal to that of the atmosphere (101000 pascals). Once the external pressure on you body exceeds this internal pressure enough your body will implode. This external pressure can be provided by water. Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet.
Octopus internal pressure equals external pressure and there is no crushing.
