shield volcanoes.
Antarctica does not have any active volcanoes. While it does have the potential for volcanic activity due to its geology, the thick ice cover suppresses any volcanic eruptions, making it the only continent without active volcanoes.
Common questions about volcanoes include: How do volcanoes form? What causes volcanic eruptions? What are the different types of volcanoes? How do scientists monitor volcanic activity? Are there warning signs before a volcano erupts?
A seismograph can detect seismic activity caused by volcanic eruptions, such as earthquakes and tremors associated with magma movement. However, it does not specifically measure volcanoes themselves.
Volcanologists are scientists who study and monitor volcanoes. They analyze volcanic activity, predict eruptions, and assess potential hazards to help protect nearby communities.
A volcanologist studies volcanoes, including their activity, behavior, and impact on the environment. Volcanologists may study various aspects of volcanoes, such as eruptions, magma composition, and volcanic gases, to better understand and mitigate volcanic hazards.
shield volcanoes
they are on oceanic lithosphere.
They are located at divergent boundaries and hot spots.
shield volcanoes are only explosive if water somehow gets into the vent
Mauna Loa is the shield volcano in the case studies that has nonexplosive eruptions every 2-3 years. It is located in Hawaii and is one of the world's largest volcanoes in terms of volume and area covered.

huge lava flows
Only insome eruptions.
Magma that is low in silica and produces nonexplosive eruptions is called basaltic magma. As basaltic magma has a low viscosity due to its low silica content, it tends to flow more easily, resulting in nonexplosive eruptions with lava flows.
when some people think of volcanic eruptions, they often imagine rivers of red-hot lava, called lava flows. lava flows come from nonexplosive eruptions. it still spurts lava but non-explosivley!
