Hey there! I'm happy to help!
Sedentary means you stay in one place and aren't very active. Nomadic means that you travel around a lot.
If there are a lot of available resources, the tribe will want to stay because having resources nearby will help them survive much easier. This would make them sedentary.
If there are scarce resources nearby, they will go away and look for more abundant resources, making them more nomadic.
Have a wonderful day! :D
B. General warming of both land and sea
Explanation:
The data on the map suggests general warming of both land and sea across the world. In fact, this is typically a global warming phase.
- The blue shade represents low temperature whereas the red shade is for higher temperature values.
- Areas around the poles should be cold due to the ice caps around the region.
- From the map, red shades can be seen in both the land and sea surface temperature maps around the pole.
- This is a big anomaly which suggests a deviation from what is known to be the normal trend in polar regions
- One can deduce a warming globe from this map.
