2. The geography is mountainous. Very curvy looking, must have been quite a struggle to climb.
3. Pros: You have natural barriers, less invaders.
Cons: You have to travel far just to trade or hunt.
4. They must have been very peaceful and calm people, seeing how they were so isolated from society. Though, Greeks lived in mountains as well and were very brutal. I can’t infer too much about their life but I know that they probably didn’t like being attacked and would rather be away from danger.

Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly.
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.
