Humanity did not spread to nearly all of the inhabitable areas of Earth until after the European voyages of discovery in the late 1400s and early 1500s.

Answer to Question 1

False

Answer to Question 2

 Heat is carried from the tropics to the poles by means of ocean and atmospheric currents.
 Ocean currents carry heat from the tropics to the poles. At the tropics, incoming energy levels are much higher than the outgoing energy levels. The energy then moves poleward where the outgoing energy is exceeds the incoming.
 Nearly half of 550 trillion calories transported by the Gulf Stream reach the high latitudes.
 Atmospheric currents are able to transport much higher levels of heat than ocean currents. This is due to the amount of water vapor in the atmosphere. The water vapor from evaporation in the tropics is moved by winds to the poles. The water vapor has more heat energy because the high latent heat of vaporization of water. An additional 540 calories per gram of heat energy is needed for liquid water to become vapor so this additional energy is carried throughout the atmosphere.
