A contour line<span> or isoline </span>connects points<span> on a map that are of </span>equal<span> value. Examples of contour </span>lines<span> or isolines are isobars (pressure) and isotherms (</span>temperature<span>). Perhaps the prototypical example of a contour </span>line<span> is that which </span>connects points of equal<span> elevation (that is, height above sea level).</span>
Answer:
The cities have a much larger populations in smaller areas, which can cause more crime and overcrowding, along with pollution.
By looking at the four graphs given and the rock layers have not been overturned. The youngest rock layer out of the four is going to be the third graph. The correct answer is the conglomerate in outcrop 3.
When two oceanic plates collide, the younger of the two plates (because it is less dense)* will ride over the edge of the older plate. *(Oceanic plates grow more dense as they cool or move further away from the Mid-Ocean Ridge). The older, heavier plate bends and plunges steeply through the athenosphere, and descending into the earth, ir forms a trench that can be as much as 70 miles wide, more than a thousands miles long, and several miles deep.
