Another answer is that some of us can\u2019t help but study it because it\u2019s fascinating. But there is more to it than that:\n<\/p>\n
- \n
- We rely on Earth for valuable resources such as soil, water, metals, industrial minerals, and energy, and we need to know how to find these resources and exploit them sustainably.<\/li>\n
- We can study rocks and the fossils they contain to understand the evolution of our environment and the life within it.<\/li>\n
- We can learn to minimize our risks from earthquakes, volcanoes, slope failures, and damaging storms.<\/li>\n
- We can learn how and why Earth\u2019s climate has changed in the past, and use that knowledge to understand both natural and human-caused climate change.<\/li>\n
- We can recognize how our activities have altered the environment in many ways and the climate in increasingly serious ways, and how to avoid more severe changes in the future.<\/li>\n
- We can use our knowledge of Earth to understand other planets in our solar system, as well as those around distant stars.<\/li>\n<\/ul>\n
An example of the importance of geological studies for minimizing risks to the public is illustrated in Figure 1.2. This is a slope failure that took place in January 2005 in the Riverside Drive area of North Vancouver. The steep bank beneath the house shown gave way, and a slurry of mud and sand flowed down, destroying another house below and killing one person. This event took place following a heavy rainfall, which is a common occurrence in southwestern B.C. in the winter.<\/p>\n
