There are limited amounts of resources in a general area. Some civilizations may not have the ability to produce resources that they need. That makes 2 routes:
1) cooperation: They can cooperate with another people group that lives in a different region and trade with them
2) conflict: They can attack/raid another people group in a different region for the resources

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>.
Answer:
Geomorphological processes and resultant topography are related with glacial, aeolian, fluvial and ground water movement.
- Outwash plain: <em>deposited mostly by water from melting glaciers.</em>
- Sand dunes: <em>not related to glaciation</em>
- Offshore bar: <em>not related to glaciation</em>
- Moraine: <em>deposited by glaciers</em>
Explanation:
Each and every geomorphological process has three types work. For e.g. erosional work, transportational work and depositional work.
- Outwash plain produced by fluvio-glacial depositional work where firstly glaciers melt and then the water flows and deposits sediments in a flat area.
- Moraine produced by glacial deposition. Glaciers carry sediments (pebbles, cobbles) and when it deposits in the valley floor it results a distinguished landform i.e. moraine.
- Sand dunes produced by aeolian action (depositional work). When wind receives obstacle in the form of tree or stone in its way it deposits sand in desert area and produce sand dunes.
- Offshore bar produced by marine processes. when sediments deposited in the coastal area in a huge quantity and friction take place between the wave and sea floor it creates offshore bar.
Fire is important because it cooked food, provided light and provided heat
