[Plate Tectonics] Ultimately, plate motion is something that rarely affects our everyday lives. However, the process is continuous and relentless, building mountains and occasionally reminding us of its presence by causing earthquakes. So, what does it mean for the future? We know that along the San Andreas fault, the Pacific Plate (upon which Los Angeles sits) is moving north at a rate of 5 cm/year compared to the North American Plate (upon which San Francisco sits). At this rate, how long will it be until Los Angeles is a suburb of San Francisco? San Francisco is 550 km north of Los Angeles.

[Tornadoes, Thunderstorms & Hurricanes] Thunderstorms thrive in unstable atmospheric conditions. Thunderstorms are less likely to form under stable atmospheric conditions. The image below shows the troposphere under stable conditions. Click on the layer of the troposphere that will experience the highest atmospheric density.
