Answer:
Imagery - vivid description/descriptive language that appeals to the senses
Literary device - a literary technique that is used for a specific effect
Step-by-step explanation:
Imagery is a tool many writers use. This term refers to the use of descriptive or figurative language to describe objects, actions, and ideas in a way that appeals to our senses (sight, hearing, taste, smell, touch). This allows us to visualize events while we read about them.
Literary devices are techniques writers use to create a special effect in their writing, convey information, or help readers understand their writing on a deeper level. Some examples of literary devices are metaphor, simile, personification, assonance, alliteration, etc.
