From the statements mentioned about Convergent Boudaries we can select the following as true.

- Convergent boundaries are where two plates move toward each other. By definition this statement is true.

-  New oceanic plate (oceanic lithosphere) is created at convergent boundaries. True, a new oceanic plate can form from the action of convergent boundaries at midocean, lava and million of years do the remaining job.

- Convergent boundaries that have subduction occurring provide a "pull" force that contributes to plate motion. False, Subducting melt and ascend trough the rock creating a volcanic eruption cone and producing an island chain.

- Oceanic plates can be destroyed at convergent boundaries due to subduction. False, The older plate will subduct due to its density and it is forced deep into the mantle, it will melt once the deepth is reached.

Most of the time in the atmosphere, the upward-directed pressure gradient force is exceeded by the downward pull of gravity.
Lisa [10]

Answer:

Ture

Explanation:

  • The pressure gradient is the force that is produced due to the rotation of earth pressure cells that creates lighter air to move upwards and heavier to move downwards due to the difference in densities of air.
  • As the air above consists of lighter elements the oceanic air mostly consist of diatomic molecules of oxygen and nitrogen thus containing a large amount of water vapor, all these molecules have a mass that are pulled down by the gravity and this pull of gravity on columns of gas applies a force what we see an atmospheric pressure.
  • The gas particles and molecules of heavy and denser matter get stuck at the ground, similarly, as the air cools is descends and warm air rises. Thus upwards and downward motion of air causes convergence and divergence of molecules.
