Question

Which of the following volcanoes is located in the United States? A. Hekla C. Mount Vesuvius B. Paricutin D. Mount St. Helens

Short answer

Mount St. Helens is located in the United States.

Step-by-step solution

Identify the Location of Each Volcano

We start by identifying the country where each volcano in the list is located. Hekla is located in Iceland. Mount Vesuvius is located in Italy near Naples. Paricutin is located in Mexico. Mount St. Helens is located in the United States, specifically in the state of Washington.

Select the Correct Option

From the list above, we clearly see that Mount St. Helens is the only volcano located in the United States. The other options correspond to volcanoes in Iceland, Italy, and Mexico, respectively.

Key concepts

Mount St. Helens

Mount St. Helens is one of the most famous volcanoes in the United States. This stratovolcano is located in Washington State, in the Pacific Northwest.
The volcano is part of the Pacific Ring of Fire, a region known for its high volcanic and seismic activity. Mount St. Helens' explosive eruption in 1980 is one of the most well-documented volcanic events in modern history. Mount St. Helens' eruption on May 18, 1980, was a catastrophic event. It resulted in the largest landslide ever recorded and a massive explosion that spewed ash for miles.
The eruption caused significant changes to the landscape, including the formation of a large crater at the summit. Key facts about Mount St. Helens:

• It is a stratovolcano, which means it is built up by many layers of hardened lava and volcanic ash.
• The 1980 eruption resulted in a loss of 1,300 feet from the summit's height.
• The eruption killed 57 people and devastated large areas of forest.
• It remains an active volcano today, with continued monitoring for potential future activity.

Volcano Locations

Volcanoes are distributed all around the Earth, but their locations are not random. Most are found along tectonic plate boundaries, where the Earth's plates meet.
These areas are prone to volcanic activity due to the movement of plates, which allows magma to reach the surface. There are three main types of volcano locations:

• Convergent Boundaries: Here, one tectonic plate dives beneath another, often creating volcanoes. This is seen in the Pacific Ring of Fire.
• Divergent Boundaries: Plates move apart, and magma rises to fill the gap, forming new crust and volcanoes, such as in the Mid-Atlantic Ridge.
• Hotspots: These are volcanic regions thought to be fed by underlying mantle that is unusually hot compared to the surrounding mantle. An example is the Hawaiian Islands.

Understanding where volcanoes are located helps in predicting potential eruptions and mitigating risks associated with volcanic activity.
This knowledge is crucial in disaster preparedness and minimizing the impact of volcanic eruptions on human populations.

Earth Science

Earth Science is a vast field that encompasses the study of the Earth's structure, properties, processes, and history. Key areas include geology, meteorology, oceanography, and astronomy.
Volcanoes play a significant role in Earth Science as they provide insights into tectonic processes and the composition of the Earth's interior. Understanding volcanoes aids in:

• Tectonics: Studying volcanoes helps us learn about plate tectonics and the movement of Earth's plates.
• Atmosphere: Volcanic eruptions can release gases and particles into the atmosphere, impacting climate and air quality.
• Land Formation: Volcanic activity contributes to the formation of new land and landscape features.
• Natural Resources: Volcanic regions are rich in minerals and geothermal energy, providing resources for human use.

Earth Science as a field helps us comprehend our planet's dynamic systems and prepare for natural phenomena like volcanic eruptions, earthquakes, and climate changes.
This understanding benefits society by improving safety, resource management, and environmental protection.
