Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope, this contrast with Uniformitarianism that suggests that the landscape developed over long periods of time through a variety of slow geologic and geomorphic processes.
To meaningfully study the past, we must assume the same or similar mechanisms operated then as now, following this idea we conclude that uniformitarianism is a more logical theory, <em>geologists then consider periodic catastrophe (volcanic eruptions, earthquakes, meteorite impacts, and storm deposits) is one of those processes uniformitarianism suggests.</em>

<span>Geography and their environment are very influential on a region’s economic activity. For example, most major U.S. cities, including New York City, Chicago, and Boston, are all located near water. This is because when these cities were founded, water was the main mode of transportation. The environment also has many economic consequences, including the type of crops that can be grown and whether or not different activities can take place outdoors.</span>
