Which regions are thought to be the most level places on earth? abyssal plains deep-ocean trenches continental slopes mid-ocean ridges

Abyssal plains

Explanation:

It is an underwater plain that is formed by the deepest floor of the oea and is about 3000 meters in depth and this plain area is thus one of the most levelled land surface as its located naet to the mod oceanic ridges it forms the area where the area is spreaded and smoothened out of the geologic processes of the earth and thus is more flat and less rugged.The abyssal plain covers more than 50% of the earth oceanic surface area.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
