Question

1. a balloon carrying weather instruments is released at the earths surface and rises through the troposphere. as the balloon rises, what will the instruments generally indicate?

a decrease in air temperature and an increase in air pressure
a decrease in both air temperature and air pressure
an increase in air temperature and a decrease in air pressure
an increase in both air temperature and air pressure

Explanation:

In the troposphere, air pressure decreases with altitude because there is less overlying atmospheric mass. Air temperature also decreases with altitude in this layer at an average rate (environmental lapse rate) due to reduced proximity to Earth's heat-absorbing surface.

Answer:

B. A decrease in both air temperature and air pressure
