Final answer:
You would look for c. precipitation and temperature patterns on a climate graph or chart to determine a region. These two variables are the most important climatic factors that influence the type of biome in an area.
Step-by-step explanation:
On a climate graph or chart, you would look for c. precipitation and temperature patterns to determine a region. Climate is a long-term average weather pattern, and these two variables are the most important climatic factors that influence the type of biome that exists in a particular area.
By analyzing the amount and distribution of precipitation and temperature data, you can identify different climate regions.
