A researcher collects air samples from 90° North latitude and finds a persistent high- pressure system. The underlying process that explains this observation is:
Sinking of cold, dense air in polar regions
At 90° North latitude, the intense cold causes the air to become dense and sink towards the surface, creating a persistent region of high atmospheric pressure at the pole.
Hence, the sinking of cold, dense air in polar regions explains the observation.
