Explain how climate differs across California's regions and connect each climate to the crops or resources that region produces.
California's regions do not just look different, they behave differently too. The coast has a mild Mediterranean climate: wet winters, dry summers, rarely very hot or very cold. The Central Valley gets much hotter in summer and cooler in winter, and its deep, rich soil, combined with irrigation water, makes it one of the most productive farming regions on Earth -- growing almonds, grapes, tomatoes, and rice. The desert is hot and dry nearly year-round, but irrigation lets farmers grow dates and citrus in places like the Coachella and Imperial Valleys. The mountains are colder and snowy in winter, which feeds rivers all year and supports forests instead of farms.
Notice the pattern: climate decides what will grow, and water decides whether farmers can grow it at all. A desert can still produce fruit if water is brought to it, which is exactly what California has done for over a century.
Mastery looks like: They can match each of the four regions to its climate and name at least one real crop or resource it produces.
Common stumbles: Assuming all of California has the same weather; forgetting that irrigation, not just climate, makes desert farming possible.
