Earth’s Surface Changes over Time (7.2.2)

Amazing but true: The 1980 eruption of Mt. St. Helens (pictured above) released a cloud of ash 8 to 10 miles into the sky. Sadly, 57 people died, it also destroyed over $1 billion dollars in property, and permanently altered the local ecosystem. As seen in the three images of Mt. St. Helen’s below. The picture shows what the mountain looked like before the eruption, and the picture on the right shows what the mountain looked like after the eruption. Identify if this phenomenon is fast changes to the Earth’s surface or slow changes (thinking of geological time scale).

As streams travel, they break down and/or erode sediment from the rocks on their banks. The running water picks up and transports the sediments further downstream. Pictured above is the San Juan River in Southeastern Utah. The twist and turns have been created over millions of years as water, wind, frost, and gravity have cut 1,000 feet into Earth’s crust. Identify if the following phenomenon is a fast change to Earth’s surface or a slow change.

In 1983, a giant landslide occurred near the town of Thistle, UT. The landslide plugged the Spanish Fork River creating a lake within a matter of days. It also destroyed roadways and railroad tracks. Identify if the following phenomenon as a fast change to Earth’s surface or slow change to the Earth's surface.(thinking of geological time scale)

Identify if this phenomenon would be considered a small scale or large scale when compared to the Earth’s surface (thinking on a global scale).
