Why the center of pressure is below the center of gravity for an inclined surface?
I'm going to guess it's for easier guidance. If center of pressure were above CG, you'd blast your rocket so that's out, we're not pulling here, we're pushing. If CP is below but too close to CG, you would have a balancing issue. Try to balance a tall object such as a broom on your hand. It's much easier to do than balancing a short object such as a pen. Easier to correct and stay under CG, with more distance.

What is the center of gravity of truck when its on inclined position?
The position of an object has no effect on the location of its center of gravity. It may have an effect on the truck's center of gravity, however, if the truck's load shifts on the incline. But that's the result of an actual shift in the center of gravity, not the result of the incline.
What is the difference between the 'center of gravity' and the 'center of pressure'?
None
Does gravity act on marbles?
Yes, gravity acts on marbles just like it does on all objects with mass. The force of gravity pulls the marble towards the center of the Earth, causing it to fall when dropped or roll downwards on an inclined surface.
Where should the center of pressure be located in relationship to the center of gravity?
"The Center of Pressure must be behind the center of gravity to have a stable rocket."

Do the center of mass and the center of gravity coincide?
Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
Applications of center of pressure?
As the intensity of pressure increases with depth so for an inclined surface CP is bellow CG. Center of gravity : a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass.
How does the pressure change as you go from the surface towards the center of the Earth's?
the pressure changes by how deep you are below see level because of gravity?
What has more pressure the center or surface of the earth?
The center, because that is where all the gravity of Earth pulls you down(this is why when you jump you come down) create lots of friction and pressure
Center of pressure on an inclined plane is?
below the centroid
Why center of pressure is below center of gravity?
I assume you are talking about a model rocket. Center of pressure needs to be below center of gravity in order for the rocket to fly straight. Mathematically, the rocket will tilt around the center of gravity but appear to be pushed from the center of pressure, hence the need for the center of pressure to be below the center of gravity, otherwise the rocket will just corkscrew off the pad. The fins move the center of pressure down.

How does pressure changes as you go from the surface to the center of the earth?
As you travel from the surface to the center of the Earth, pressure will increase enormously, because of the increasing weight of what is above you.

Is earth's gravity the same on the surface as it is in the center of the earth?
No. At the centre of the earth the acceleration due to gravity is ZERO
