A gentle rise and fall, a dancer at sea's edge, whispering greetings to the shore, yet never speaks a word.

I am used, never kept full, what you give I expel. Yet you need me. See the transfer? Nothing given back fell. Kept behind doors in darkness, until you need my help. Corner cavern arachnids, Or a twister may dwell.

When an egg hits a hot pan it goes zzzzzzzz Used exclusively to describe food in a pan, bacon, omelet, steak, stir-fries, fajitas, and grilled seafood served on cast-iron plates. What verb am I?

I reach to the sky, though arms I have none. The top of a cathedral, or a point of alarm. I the tip of a tower, tapering up with silent power.

I glide without wheels through streets made of waves, or hang from a cable with mountain views to gaze. One rides the water, one rides the sky, both carry travelers passing by.
