Why is the pressure at a given point in a fluid equal from all directions ie surely the vertical forces and the horizontal force forces can be different so long as they balance separately?

OK, then consider a diagonal direction, and the forces in that direction.
If the horizontal COMPONENT of force in that direction were not equal to
the horizontal component of force in the opposite direction, then some fluid
would move horizontally until those components were equal. Likewise, if the
vertical component of force in that direction were not equal to the vertical
component of force in the opposite direction, then some fluid would move
vertically until those components were equal. Eventually, once things settle
down, every component of force at that point in the fluid must be equal,
so the pressure on a tiny element of area at that point doesn't depend on
what direction the area is facing. qed
Pretty good for the spur of the moment, eh !

Air pressure exerted equally on an object from different directions is what?
balanced pressure
What Air pressure exerted equally on an object from different directions is what type of pressure?
constant pressure
Why is air pressure different in the different layers of the atmosphere?
The different "layers" are classifications of horizontal sections of the atmosphere, volumes which exhibit different attributes. The high and low pressure regions are areas where the atmosphere is thicker or thinner.
What are rocks that move in opposite horizontal directions?
Convergent plate boundary.
How do you know wind speed and directions?
Jet Streams, air pressure, oceanography, climatology, different factors working together
What are the Laws of liquid pressure?
1) Pressure increases with depth 2) Pressure is the same on the same horizontal plane of the liquid 3) Pressure varies with different liquids on the same horizontal plane 4) Pressure is the same in all directions about a point 5) A liquid seeks its own level

Why is there no horizontal buoyant force on an submerged object?
Because the buoyant force is the result of different pressure at different depths, and there is no difference in pressure horizontally.

1. balanced pressure

Convergent plate boundary.
How does pressure exerted by a solid object on a surface differ from pressure exerted within a liquid or gas?
In a liquid or gas the pressure at any given point is the same in all directions. In a solid the pressure can vary depending on direction. So, for example, the vertical pressure can be greater or less than the horizontal pressure.
How do you know wind speed and directions?
Jet Streams, air pressure, oceanography, climatology, different factors working together
What causes foliation on a metamorphic rock under what cirumstances would you expect this to happen?
Foliation is created when pressure pushes different parts of the rock in different directions.
What determines the direction of diffusion of gases in plants?
Partial pressure (the pressure of each gas separately).
