What literary term is being used in the following piece: The hot summer sun beat relentlessly down,
casting an orange glare over the fields, houses, and the river.
Even the fragrant yellow flowers bordering the river hung wilted and dry.
Our sun-baked backs ached for relief.
We quickly pulled off our sweaty clothes and plunged into the river,
but the cool water only stifled us and we soon climbed onto the brown, dusty bank.
Our parched throats longed for something cool-a tall frosted glass of lemonade.
