Project Two

For our second Lab we read about weather patterns and other aspects such as dewpoint, humidity, precipitation, etc. I learned that the more humid the air is...the more likely it is to precipitate. The temperature affects the type of precipitation and the moisture content also. If it is hotter...its likely to rain over snow, and will be more humid due to more evaporation. If its colder its more likely to snow, and will be less humid. Thats why Michigan has a muggy summer and dry, bitter winter. Lanslides occur more in areas with warmer, more humid climates where the chance of rain is high.

Project One

Today we experimented with different mediums (Snow, Water, and Dirt) and how quickly they heated and cooled. I learned that the snow cooled the quickestand melted really fast under heat. This relates to landslides in that when snow melts, the water that is formed mixes with dirt and creates a soupy mixture. The mixture slides off the hillsides.
