Lift is the upward force that opposes the force of gravity.
Since gravity causes objects to fall downward, rather than upward, I would describe the upward force of g, at the surface of the Earth, as -9.8 meters/second2.
'Lift' is an upward force on a plane. Upward force on a bird's wings is also called 'Lift'.
It is called Lift. The difference in pressure above and below the wigs as a bird moves through the air produces an upward force that causes the bird to rise.

The force that causes warm molten rock to move upward to the mantle is called convection. Convection happens when parts of the tectonic plate break off and melt.

It said that a softball is harder to hit because of the force it comes in at is greater in the highest levels of softball then is baseball, also the underhand motion causes the ball to have an upward movement which is hard to master then the downward movement of a baseball.
Decrease and become closer to the dewpoint. :-)
