Question

scientists can use infrared waves to monitor volcanoes! they use a device called a spectrometer. heres how it works.infrared waves emitted from lava are absorbed by volcanic gases. each type of gas absorbs unique wavelengths of infrared waves. a spectrometer positioned above the volcano measures these wavelengths. then, these measurements are used to identify the types of gases emitted by a volcano. monitoring volcanic gases helps scientists predict the likelihood of a volcanic eruption.spectrometer above the overlook vent in halemaumau crater in hawaiicomplete the sentences.volcanic gases infrared waves that are from lava. a spectrometer measures the of these infrared waves to determine the types of gases emitted by the volcano.

Explanation:

The answers are derived directly from the provided text describing how spectrometers monitor volcanoes. Key details about the interaction between volcanic gases, infrared waves from lava, and spectrometer measurements are extracted to fill the blanks.

Answer:

Volcanic gases absorb infrared waves that are emitted from lava. A spectrometer measures the wavelengths of these infrared waves to determine the types of gases emitted by the volcano.
