“Aqua” is a morpheme meaning , just like the water you are learning about in your science unit. Unlike “terr,” it is a type of morpheme that can stand by itself as a word. You may know it better as the name of a blue-green color (like the color of water).

“Aqua” is found in many words that have something to do with water. You will probably come across some of them as you learn about land and water. Let’s look at some examples:

“Aquatic” is an adjective (a describing word”) meaning “living in, or having to do with, water”. “Whales, dolphins, and shrimp are all aquatic creatures.”

“Aquarium” is a noun (a person, place, or thing”) and is “a container (such as a glass tank) in which living water animals or plants are kept,” or “a building or establishment where collections of living water animals and plants are kept. “At the aquarium, I saw many kinds of fish and even some sharks!”

“Aquifer” is a noun and is “an underground laver of rock, sediment, or soil that contains ground water, often for use in wells.” ‘The well gets its water from an aquifer under the ground.”

Choose the words (from above) to complete the sentences: If you want to learn more about animals that live in the ocean, you could visit an____________________________. Rain that is absorbed by land flows under the ground to areas called ____________________, which can be used to build wells.
