Earth traveler: outward or inward bound
transd
the temperature at the surface of the earth averages
15°c. if you were to travel to a point 15 kilometers from
your current location at roughly the same elevation,
you'd probably experience little change in temperature.
but what if you were to travel the same distance above
or below the earth's surface? use the graph
tool to explore how temperature changes
above and below the surface of the earth.
