During a volcanic eruption, you might see and hear lava and ash bursting through the surface of the Earth. Explorers could find unique sea life and terrain in the deepest parts of the oceans. A pond warming up in the sun happens gradually over a long period of time, unlike the sudden strike of lightning on a tree. A puppy hiding under a blanket could be revealed if the blanket is moved to expose the previously hidden puppy. A snail may contract into its shell if it feels threatened or in danger. A constant sound is one that occurs continuously without stopping, like a drip of a faucet. Saying "Hi" to someone but not getting a response right away could make you feel awkward or unsure
