Asea arch is formed through wave erosion.
a. true
b. false

Answer : The given statement is true.

Explanation:

Sea arch is a natural opening formed in the cliff by the action of pounding power of crashing waves. In this erosive action of water plays an important role in formation of sea arches.

A part of cliff which doesn't comes in contact of waves remains intact results in formation of an arch upon the eroded portion of the cliff.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
