expose to fresh air
aer (air) + ate (suffix forming verbs)
In addition to creating tunnels for air and water to travel through, worms mix up the elements in the soil, by moving, eating, and excreting. This produces natural fertilizers that help plants grow.

vehicles are useful tools for wildlife researchers because they can easily visit remote locations and observe animals from a distance.BBC (Aug 17, 2015)
aer (air) + al (suffix forming adjectives)
An unmanned aerial vehicle is also known as a drone. But unlike the three-word phrase, "drone" has a negative tone, which might have originated as an onomatopoeic description for the sound of a male honeybee. Since male honeybees don't actually make honey, "drone" became synonymous with a useless, lazy worker.
an acrobat who performs above the ground, as on a trapeze
aer (air) + al (suffix forming adjectives) + ist (suffix forming nouns)
The prefix "acro" means "highest, topmost, at the point end" and the Greek verb "bainein" means "to walk." Thus, an acrobat used to be someone who walks on tiptoe or on a high tightrope. Now, an acrobat can be any gymnastic performer, while an aerialist is an acrobat who performs high in the air.

Spontaneous physical games such as hide and seek, tag and kickball can be great sources of
exercise.US News (Aug 10, 2015)
aer (air) + bios (life) + ic (suffix forming adjectives)
As the example sentence suggests, spontaneous aerobic exercise is not the same as aerobics. While both can help the circulation of air and blood through the body, aerobics refers to specific routines, often set to music, that aim to improve overall fitness (this includes flexibility and muscle strength).
living or active in the absence of free oxygen
an (prefix meaning "without") + aer (air) + bios (life) + ic (suffix forming adjectives)
The prefix "micro" means "small" and "microbe" now means "a small life form." But in Greek, the word would have translated as "short-lived." However, because some anaerobic microbes can grow without oxygen, yet also use it if it's available, they can thrive in a variety of environments, or go into dormant states and perhaps be revived millions of years later.

aer (air) + bios (life)
According to the roots and definition, humans can be considered aerobes. But the word mainly refers to microorganisms. Obligate aerobes will use as much oxygen as they can get, while microaerophiles need a certain level of oxygen to grow, but high concentrations of it will poison them.

aer (air) + solvere (to loosen, dissolve, scatter)
As the roots, definition, and example sentence show, an aerosol does not just come in a can. In addition to being sprays of artificial chemicals (such as paint or pesticides) or natural elements (such as the sea), an aerosol can be created by human breath, which can contain harmless or disease-causing particles.

the bumblebee shouldn’t be able to fly, but the bumblebee doesn’t know that so it goes on flying anyway.”Time (Aug 3, 2015)
aer (air) + dynamis (power) + ic (suffix forming adjectives)
The example sentence was said by the founder of a cosmetics firm, who succeeded despite facing many obstacles. Bumblebees are fat and furry, so they look like they can't fly. But a bumblebee beats its wings about 200 times a second; with each beat, a dynamic stall is created that separates the flow of air and produces a vortex above the wings to lift it up.
the theory and practice of navigation through air or space
aer (air) + nautes (sailor) + ics (suffix forming names of sciences or disciplines)
In the example sentence, "aeronautics" and "aviation" are synonyms that refer to the same event. But as the roots and definitions suggest, "aeronautics" is a more scientific term, while "aviation" is "the art of operating aircraft" (the Latin "avis" means "bird").

Florida, with its mix of airports and military installations, is a leading state in the nation when it comes to the

In addition to Cape Canaveral, where astronauts launch into aerospace, Florida hosts the National Naval Aviation Museum. Spreading over 350,000 square feet and 37 acres, the museum is the largest of its kind in the world. Visitors can try out flight simulators, examine uniforms and historic documents, or wander among 150 restored aircraft that had served in the Navy, Marine Corps, and the Coast Guard.

aer (air) + dromos (course)
The word was modeled after "hippodrome" (the Greek "hippos" means "horse"), where chariots raced around a course. It took on a negative tone when it was used to refer to a fixed race or to a place for circus performances. Despite this, the British still prefer "aerodrome" while Americans line up at airports.
aer (air) + phagein (to eat) + ia (suffix forming names of countries, flowers, diseases)
Aerophagia can be caused by chewing gum, smoking, drinking soda, eating too fast, being too anxious, or undergoing surgery that requires anesthesia. On the mild side, aerophagia can lead to belching and flatulence. But it can also lead to severe abdominal bloating, intestinal pains, or a rupture of the esophagus.
