3

How are altitude and average temperature related?

Inversely

4

What two climate effects are typically observed in biomes near large bodies of water?

Greater precipitation, more stable temperatures

5

What is a combined precipitation and temperature graph for a certain biome?

7

Where does primary succession occurs?

In essentially lifeless areas

8

When does secondary succession occur?
