The upward thrust which the surrounding fluid exerts on an object is referred to as the force of buoyancy. This thrust acts through the centroid of the displaced volume, referred to as the centre of buoyancy. The centre of buoyancy is not the same as the centre of gravity which relates to the distribution of weight within the object. If the object is a solid with a uniform density exactly the same as water and the body is immersed in water the force of buoyancy will be exactly equal to the weight and the centre of buoyancy will be the same as the centre of gravity. The object will be in equilibrium with the surrounding fluid.

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 relationship between the center of buoyancy and the center of gravity in an object's stability in water?
The relationship between the center of buoyancy and the center of gravity in an object's stability in water is that for an object to be stable, the center of gravity must be located below the center of buoyancy. This ensures that the object will remain upright and not tip over in the water.
What is a metacentric diagram?
A metacentric diagram is a vessel (ship) stability diagram that shows the relative positions above and below the metacenter of the center of buoyancy and the center of gravity, respectively. Use the link to the Wikipedia article to view one and see how it looks. Follow along and see how it works. When a vessel floats in water, its center of gravity is below its center of buoyancy. That allows gravity to pull down on buoyancy from below the bouyancy to pull up on gravity from above (if it is permitted to say it that way). If the center of buoyancy slips below the center of gravity, the vessel will roll over. Visualize that. And the closer the two centers are, the less stable the vessel. That is, the more prone to rollover it is. The "sweet spot" between the centers of buoyancy and gravity is the metacenter. It's important in evaluating a ship's stability.
How do we know wheater abody is in a stable or unstable equilbrium due to position of its centre of gravity?
If the center of gravity of an object falls below its support base, it is in stable equilibrium. If the center of gravity falls outside the support base, it is in unstable equilibrium. You can determine the stability by assessing the relationship between the object's center of gravity and its base of support.
How does gravity cause air pressure?
Gravity causes air pressure by pulling air molecules towards the Earth's surface. The weight of the air above creates pressure on the air below it. The higher you go, the lesser the air pressure due to less weight above pushing down.
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 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?
Why center of pressure is always below cg?
It's not. By your use of the term "center of pressure" I'll make a guess that you're talking about model rocketry. In that case, the center of pressure can be above or below the center of gravity, but you must make it lower in order to make your rocket stable.When a rocket in flight is tipped - say by a gust of wind or some such - it rotates about its center of gravity. (This actually is true of any object in mid air or space, not supported by an outside force.) When the rocket is moving straight along its central axis the fins are not really doing anything. But when the rocket is tipped and its velocity vector is not along its axis, then the fins generate a lateral force, which acts through the center of pressure. (That's what "center of pressure" means.) Now, if the center of pressure is above the center of gravity then the force that the fins apply will make the rocket tip further, and the rocket is unstable. If the center of pressure is below the center of gravity then the force from the fins straightens the rocket out, and the rocket is stable.This is much easier to explain with pictures. See the related link for a fully illustrated explanation.

Supposing the center of the earth was safe and you could cut a hole down to the center if you got down there would the force of gravity keep you there or would it squish you?
As you go down below the surface, the force of gravity would decrease, because now part of the Earth is attracting you from above, and less from below. At the center of the Earth, gravity would be zero.
What is a metacentric diagram?
A metacentric diagram is a vessel (ship) stability diagram that shows the relative positions above and below the metacenter of the center of buoyancy and the center of gravity, respectively. Use the link to the Wikipedia article to view one and see how it looks. Follow along and see how it works. When a vessel floats in water, its center of gravity is below its center of buoyancy. That allows gravity to pull down on buoyancy from below the bouyancy to pull up on gravity from above (if it is permitted to say it that way). If the center of buoyancy slips below the center of gravity, the vessel will roll over. Visualize that. And the closer the two centers are, the less stable the vessel. That is, the more prone to rollover it is. The "sweet spot" between the centers of buoyancy and gravity is the metacenter. It's important in evaluating a ship's stability.
What cause air pressure?
Air pressure is caused by the weight of the air above us pressing down on the air below. This pressure is a result of Earth's gravity pulling the air molecules towards the surface. Temperature changes and weather systems can also affect air pressure.
