Increases with depth:
The pressure exerted by a liquid increases with depth. This can be explained by considering the concept of pressure and the properties of liquids.
Pressure:
Pressure is defined as the force exerted per unit area. In the case of a liquid, the pressure is exerted in all directions. This is because liquids are considered to be incompressible, meaning they cannot be easily compressed or squeezed into a smaller volume.
Properties of Liquids:
Liquids have the property of transmitting pressure equally in all directions. This property is known as Pascal's principle. According to Pascal's principle, any change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.
Explanation:
When we consider a liquid at a certain depth, there is a column of liquid above it. The weight of this column of liquid exerts a force on the liquid below it.
As we go deeper into the liquid, the height of the column of liquid above the point of interest increases. This means that the weight of the column of liquid also increases. Since pressure is directly proportional to the force exerted and inversely proportional to the area over which the force is distributed, an increase in the weight of the column of liquid leads to an increase in pressure.
Therefore, as the depth increases, the pressure exerted by the liquid also increases. This can be observed in various real-life examples, such as the increased pressure felt by divers as they go deeper into the water.
Conclusion:
In conclusion, the pressure exerted by a liquid increases with depth. This is due to the weight of the column of liquid above the point of interest, which leads to an increase in the force exerted and, consequently, an increase in pressure.

The pressure exerted by a liquid increases with depth.
As we go we deeper in a liquid the pressure of liquid increases. As the depth of liquid increases the weight of liquid column pushing down from above increases and hence the pressure also increases.
