The geography of a region affects its weather because the shape of landforms influences the flow of ocean currents and wind. Weather is extremely dependent on wind patterns and ocean currents, because they could be arranged in a way that causes windstorms such as tornadoes, windy rain, or others. As for ocean currents, natural disasters such as tsunamis and even food shortages! The temperature of the sea can change and cause marine life to die out, which shortens food quantities for people who depend on it.
