Anything that has mass exerts a gravitational field, so yes, earth exerts one.
According to Newton's Third Law of Motion, when you exert a force on an object, the object exerts an equal and opposite force back on you. This means that for every action, there is an equal and opposite reaction.
The same reason bricks exert downward pressure. Gravity.
Yes, water exerts pressure on the hull of the submarine.
The force that the machine exerts is the out put force. This is the science definition.
