If sea level temperature is 100^$\circ$F (10^$\circ$C),what is the temperature at an altitude of 10,000 feet (610m)? (Use the lapse rate.) A)90^$\circ$F (32.2^$\circ$C) B)65^$\circ$F (18.3^$\circ$C) C)50^$\circ$F (10.0^$\circ$C) D)0^$\circ$F (-17.8^$\circ$C)

According to the lapse rate, temperature decreases by approximately 3.5F/1000ft (6.4C/1000m) of elevation gain. So, for an altitude gain of 10,000ft (610m), the temperature would decrease by approximately 35F (19.4C). Therefore, the temperature at an altitude of 10,000 feet would be: 
100F - 35F = 65F (or 37C - 19.4C = 17.6C)
Therefore, the best choice is B.
