Describe in your own word how changes in the amount of ice covering Earth's surface can affect earth's temperature

If ice begins to melt, it can spread across the oceans making the seas colder. If that happens, some arctic species will die and become extinct.

Explanation:

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.
