At first there was nothing as the sun dropped lower.

At last the sun dropped low and the sky turned to a light green.

The sun dropped so that it wasn't far from dark.

The sun had almost dropped from the sky as he reached 50th Street.

To their right, the sun was dropping into the sea.

The sun dropped behind them, and they plunged into the night.

The sun had dropped from sight and it was suddenly cold.

The sun was dropping behind the hills before they were ready.

By the time dinner was over, the sun had dropped behind the hills.

Yet the sun did drop below the horizon for a short while every day.
