Explanation:

1. For "Earth’s ____ during rotation is responsible for the seasons and prevents temperature extremes", the term related to Earth's rotation and seasons is "tilt" (Earth's axial tilt causes seasons).
2. For "Earth’s ____ acts as a protective blanket, and provides air to breathe", the atmosphere is the protective blanket with air, so "atmosphere".
3. For "Earth’s perfect size creates just enough ____ to keep the other living necessities in balance", gravity is related to Earth's size and keeping things in balance, so "gravity".
4. For "Earth’s ____ keeps it from receiving too much heat from the sun", distance from the sun affects heat received, so "distance".
5. For "The ____ layer of the atmosphere shields Earth from ultraviolet radiation", the ozone layer shields from UV, so "ozone".
