Question

part e our planet has frozen poles. what property does frozen water have that might be useful in searching for other planets with frozen poles?

Explanation:

Frozen water (ice) has a specific spectral signature. Telescopes and remote - sensing instruments can detect this signature. By looking for this unique spectral pattern in the infrared or other wavelength ranges, scientists can identify regions on other planets that might have frozen water (ice) at their poles.

Answer:

Frozen water (ice) has a unique spectral signature that can be detected by remote - sensing techniques (such as in the infrared spectrum), which can be used to search for frozen poles on other planets.
