The changes in air temperature and atmospheric pressure will normally be recorded by a weather balloon by a decrease in both air temperature and atmospheric pressure.
<h3>What is the troposphere?</h3>
The troposphere refers to the first and lowest layer of the atmosphere of the Earth where most weather phenomena occur.
The changes in air temperature and atmospheric pressure will normally be recorded by a weather balloon when it is released at Earth's surface and rises through the troposphere by a decrease in both air temperature and atmospheric pressure.

Answer:
d) Chemical composition of its outer regions
Explanation:
Spectroscopy is the study of spectral lines, it's an important part of studying the chemistry that goes on in stars and interstellar clouds, spectral lines can give relevant information because every atom or molecule gives off light at a specific frequency, thus, astronomers can look for gas containing a particular atom or molecule by tuning the telescope to one of the gas's characteristic frequencies. Therefore, we can know the chemical composition or a star's outer regions analyzing the spectral lines.
Even though the spectral shape of a blackbody continuum depends on the temperature of the object an there's a relationship between an object’s temperature and the peak of its spectrum, we don't consider this answer as correct because we are not measuring spectral lines but the continuum.
I hope you find this information useful and interesting! Good luck!
