When a horizontal pressure is applied to rocks, the earth's surface will form lines that are perpendicular to the direction of the pressure. This can be compared to folds in a wrinkled rug lying on a floor.

What happens to air pressure as distance from earth's surface increases?
the air pressure increases
When is pressure more?
Pressure is generally higher when the force applied to a surface is greater or when the area over which the force is applied is smaller. For example, stepping on a sharp object exerts more pressure than standing on a flat surface because the force is concentrated on a smaller area. Additionally, pressure increases with depth in a fluid due to the weight of the fluid above.
What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
The amount of horizontal force required to start in motion an object sitting on a horizontal surface must be greater than the force of static friction acting on the object. This is because the force of static friction opposes the applied force until the object starts moving.
Describe what happens to rock during pressure release?
Rock deep within the Earth is under great pressure from the rocks around it. As the rock above it is weathered and eroded, it moves closer to the surface, and the pressure from above is lessened. What happens to the uplifting rock that was once under great pressure depends on the rock type, but can vary from simple exfoliation of its surface to widespread cracking and faulting of the rock body from the release of pressure.
What is divided by surface area to calculate pressure?
That is the force F. p = F / Awhere:p is the pressure,F is the normal force,A is the area (surface).
What happens to earth's surface when horizontal pressure is applied to rocks?
When a horizontal pressure is applied to rocks, the earth's surface will form lines that are perpendicular to the direction of the pressure. This can be compared to folds in a wrinkled rug lying on a floor.
What happens when three blocks are placed on a frictionless horizontal surface?
When three blocks are placed on a frictionless horizontal surface, they will remain stationary unless an external force is applied to them. If a force is applied to one of the blocks, it will move in the direction of the force, while the other blocks will remain stationary due to the absence of friction.
What does the pressure on a surface depend on?
The pressure on a surface depends on the force applied perpendicular to the surface and the area over which the force is distributed. It is calculated as the force divided by the area. The pressure increases with increasing force or decreasing area.
How does horizontal convergence and divergence affect surface pressure?
Horizontal convergence leads to rising motion and lower surface pressure, as air piles up at the surface. Conversely, horizontal divergence results in sinking motion and higher surface pressure, as air spreads out and departs from the surface. These patterns are key components of atmospheric circulation and can influence weather systems and patterns.
What is a force applied to a confined fluid?

How is pressure related to the thrust exerted on a surface?
Pressure is the force exerted per unit area of a surface. The greater the pressure applied on a surface, the greater the thrust exerted on that surface. This relationship is described by the equation: Pressure = Force/Area.
What happens when three blocks are placed on a horizontal frictionless surface?
When three blocks are placed on a horizontal frictionless surface, they will remain stationary and not move because there is no force acting on them to cause them to move.
What happens when force is applied to a flat surface?
When force is applied to a flat surface, it can result in the surface deforming or breaking depending on the magnitude of the force. The surface may also experience frictional forces depending on the material and the amount of force applied.
What happens to surface area of a tire when pressure is increased?
the surface area decreases.
Horizontal movement of air in relation to the earth's surface?
Horizontal movement of air in relation to the Earth's surface is called wind. Wind is caused by the uneven heating of the Earth's surface, creating differences in air pressure that lead to air moving from high pressure areas to low pressure areas. The speed and direction of wind are influenced by factors like temperature, pressure, and the Earth's rotation.
How does surface area and force affect pressure?
Pressure is force per area, so P = F/A where pressure is P, force is F and A is area. So Pressure is directly proportional to the force exerted on a surface. So increasing a force by a factor of 2, say, increases the pressure on the surface by 2 also.
How can the pressure acting on the surface be increased by the force acting on the surface?
Simply pressure is the force per unit area. So Pressure is directly proportional to the force applied. Hence by increasing the force we can increase the pressure.
