Neil deGrasse Tyson explains the difference between climate and weather while walking on a beach with a dog. He mentions that climate is the weather of a region over a long period of time, while weather is short-term. He uses the dog's path to illustrate the variance of weather patterns and his own path to illustrate the consistency of climate.
Bill Nye is obssessed with erosion and explains that rocks change over time. He explains what causes weathering (although he calls it erosion): water, ice, wind, sand, and chemicals. He illustrates the process of erosion in his lab.
Strong stormy weather can cause flash floods. This is when heavy rain pours down on a region and very quickly floods an area. Scientists are trying to find ways to warn people before flooding hits by studying weather patterns.
