What is the process of soaking grain in water, allowing it to germinate, and then drying it to prepare it for brewing beer?

Malting

Malting is a crucial step that activates enzymes within the grain, which later convert starches into the sugars needed for fermentation. A memorable way to think of it is that the grain is "tricked" into starting to grow before the process is halted by heat. This technique is what gives beer its characteristic color and toasted flavor profiles.
