There are 169 potentially active volcanoes in the United States. This map indicates the location of these volcanoes using multi-colored triangles. The different colors indicate levels of concern based on data from scientists observing them.

Based on the map, what pattern can be determined about the volcanoes' location?

This is a map of different active volcanoes in California and their hazard levels and zones.

Based on the map provided, what pattern can be identified with the location of the volcanoes?

This map shows Fire Island, which is off the coast of Long Island, New York. Fire Island has been studied since the 1800s, and using ariel photos and historical maps, the United States Geological Survey has been tracking both long-term and short-term changes to the island. This map is focused on long-term changes and identifies coastal shoreline changes from 1830 to 2007. Crews have been working to restore part of the island, use the island as a barrier to protect landforms behind it, and create safe conditions for tourists.

Using the legend and provided map describe a pattern that can be identified.

The two maps below display important information used to keep people safe. The first map is of the United States and its volcanic activity. Each triangle represents an active volcano being monitored by scientists.

The second map highlights what is known as the "Ring of Fire." The areas highlighted in red are zones of frequent earthquakes. The blue lines represent deep oceanic trenches.

What pattern can be identified using both graphs?

Below are maps of Dauphin Island which is off the coast of Alabama. The maps are models to show what would happen if the island faces less frequent and less intense tropical storms, moderate frequency and moderate-intensity storms, and more frequent and more intense storms. After analyzing the three maps, which frequency and intensity of storms would lead to the LEAST amount of erosion and destruction?

Below are maps of Dauphin Island which is off the coast of Alabama. The maps are models to show what would happen if the island faces less frequent and less intense tropical storms, moderate frequency and moderate-intensity storms, and more frequent and more intense storms. What pattern can be described after viewing these maps?

Less frequent and less intense storms

Moderate frequency and moderate-intensity storms

More frequent and more intense storms

A map of the tectonic plates of the Earth showing the different boundary types in different colors. In red are the areas where the tectonic plates collide. These areas are known as convergent boundaries. In yellow are the divergent boundaries, or places where the plates are spreading. If the plates slide past one another they are highlighted in orange.
