Buoyancy
Gravity pulls "down" and the opposite force is provided by whatever is beneath the object.
This is called a "bouyant" force. It is due to the difference in water pressure between the top of the object and the bottom of the object. Water pressure increases with depth.
Water is denser than air, and thus has a buoyancy effect that supports your weight more. You feel lighter because you are lighter. A scale under you would reflect the difference. Bear in mind, there is a difference between "weight" and "mass". Your mass would still be the same.

bouyant force
When you are underwater, buoyancy is the force that pushes you up. This force is created by the displacement of water as your body takes up space in the water, causing an upward force that counteracts the downward force of gravity.
The force from water that pushes things up is called buoyancy. It is caused by the pressure difference between the top and bottom of an object submerged in water, resulting in an upward force that opposes the force of gravity. Buoyancy is why objects float in water.
It is a force which acts in the upward direction.
The force that pushes heated rock upward is typically convection currents in the mantle. As rock near the Earth's core heats up, it becomes less dense and rises towards the surface. This movement creates pressure that pushes the rock upward.

It is one of the forces it lifts it up
Upthrust, also known as buoyancy force, acts opposite to the direction of gravity. It pushes objects upward when they are submerged in a fluid, such as water.
No. Upward means... well, upward. "Normal" in this context means "perpendicular" or "at a right angle" - i.e., at a right angle to some surface you are considering. This may happen to be upward as well, but it can be just about any direction.
buoyancy is the upward force that water exerts on an object. :)
The buoyant force is an upward force exerted on an object immersed in a fluid, such as water or air. It is considered a push force because it pushes the object upwards, opposing the force of gravity pulling the object down.
The force that pushes us up is buoyancy, which is the upward force exerted by a fluid on an object immersed in it. This force is a result of the difference in pressure between the top and bottom of the object.
The upward force of water on air is called buoyancy. It is a result of the difference in density between water and air, causing objects submerged in water to experience an upward force.
