Question 2

  B) Like Earth, nitrogen is the chief atmospheric gas.
  C) Both are chiefly carbon dioxide, but at Mars it can freeze as dry ice.
  D) Mars is rich in oxygen, like ours, accounting for its red surface.
  E) Both are too hot for water to now exist as a liquid at the surface.

Answer to Question 1

The solar thermostat is analogous to the thermostat at home: it works to maintain a constant temperature. If the solar core were to increase in temperature, the nuclear fusion rate would soar, generating excess energy that increases the pressure and pushes the core outwards. This expansion cools the core back to its normal operating temperature. Similarly if the solar core were to decrease in temperature, the nuclear fusion rate would plummet and gravity would overcome thermal pressure and contract the core. As the core contracts, it heats up and the core returns to its normal operating temperature.
