1. Explain how infrared radiation works (own words) 2.how is infrared radiation applied? Come up with a way to use infrared radiation to solve a problem 3. How will you interpret the measurements you will be looking at or how is this phenomena affecting earth ?

the answer is :

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
