 c)abyssal plain

The section of the ocean floor that makes up half of the surface of earth is abyssal plain.  

Explanation:

At a depth between 3000 meters and 6000 meters in the ocean the dominating land form is the abyssal plain.

Abyssal plains are formed as a result of sea floor spreading and melting of lower oceanic crust. The deposition of silt and sediments on oceanic crust causes the formation of abyssal plains.  

The abyssal plains exert considerable influence in ocean carbon recycling as well as calcium carbonate dissolution.                            

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
