Which one would have more gravitational mass? one kilogram of iron dropped from 200 meters height or one kilogram of paper on the ground?

The piece of paper because gravitational forces between 2 objects depend on the distance between their centre points and the mass, so since they are both the same mass, then the only factor which would determine the force is the distance. The distance between the centre of the earth and the paper is smaller than the iron, so the force would be greaater 

Which principle states: "geologic processes taking place on earth today operated similarly in the past and can be used to explain past geologic events"? a. lateral continuity

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.
