The magma that comes out of the mid atlantic ridge is at a temperature of roughly 1200 degrees Celsius while the atlantic ocean has an average temperature of 5 degrees celsius. How much would the magma coming up
through the ridge change the temperature of the Atlantic ocean?

The rearrangement of particles in a physical change. hope this

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
