Final answer:
The areas west of the mountain range have more precipitation and more moderate temperatures, while the areas east of the mountain range have less precipitation and more extreme temperatures.
Step-by-step explanation:
The relative amount of precipitation and temperature variation for the areas west and east of the mountain range can be described as:
- More precipitation & More-moderate temperatures: The western side of the mountain range experiences more precipitation due to the rain shadow effect, while the temperatures remain moderate.
- Less precipitation & More-extreme temperatures: The eastern side of the mountain range, also known as the rain shadow, receives less precipitation and experiences more extreme temperatures.
Overall, the areas west of the mountain range have more precipitation and more moderate temperatures, while the areas east of the mountain range have less precipitation and more extreme temperatures.
