Which of the following accurately describes one way that coastal mountains affect a region's climate?
A
They decrease humidity on the windward side by absorbing moisture from the air.
B
They increase temperatures on both sides of the mountain by blocking cold ocean air.
C
They cause moist air to rise and cool, resulting in increased precipitation on the windward side.
D
They have no significant effect on precipitation patterns in the region.
Verified step by step guidance1
Understand the concept of orographic effect: Coastal mountains influence climate by causing moist air from the ocean to rise as it encounters the mountain range. As the air rises, it cools and condenses, leading to precipitation on the windward side of the mountains.
Analyze the options provided: Evaluate each statement to determine its accuracy based on the orographic effect and its impact on climate.
Option 1: 'They decrease humidity on the windward side by absorbing moisture from the air.' This is incorrect because mountains do not absorb moisture; instead, they cause air to rise and cool, leading to precipitation.
Option 2: 'They increase temperatures on both sides of the mountain by blocking cold ocean air.' This is incorrect because mountains primarily affect precipitation patterns rather than significantly altering temperatures on both sides.
Option 3: 'They cause moist air to rise and cool, resulting in increased precipitation on the windward side.' This is correct because it accurately describes the orographic effect and its impact on the windward side of coastal mountains.
