Answer:
"Ripples spiraled like corkscrews on the dark brown water."
"The little fish darted this way and that in streaks of silver."
Step-by-step explanation:
Imagery is describing how something feels, look, smells, or tastes like. The author does this so that they can help us picture what they want us to in their book.
In those two sentences from the story Terrible Things, the author described the ripples ar corkscrews, which is describing how the movement of the water looked like: corkscrews. And the author also described the color of the water: brown, and the color of the fish: silver and how they were streaks because they were moving so fast.
