Where does most of the earth's volcanic activity take place?
Where Does Volcanic Activity Occur? Myth: Most of the Earth's igneous rocks are produced at the "Ring of Fire." Fact: 70% of the Earth's surface is ocean floor, which is made of basalt, an igneous rock produced at mid-ocean ridges. The ridges are the most volcanically active features on the planet.
What country has the most earthquakes in the world?
Indonesia is in a very active seismic zone, also, but by virtue of its larger size than Japan, it has more total earthquakes. Which country has the most earthquakes per unit area? This would probably be Tonga, Fiji, or Indonesia since they are all in extremely active seismic areas along subduction zones.Where are most of the world's active volcanoes found?
The result: More volcanoes and earthquakes in places like California and Japan. For land-based volcanoes, Indonesia is the hotbed for fiery craters since it is part of the roughly 25,000 mile stretch circling the basin of the Pacific Ocean known 'ring of fire' where most active volcanoes lie.What state has the most volcanoes?
"There are about 169 volcanoes in the United States that scientists consider active. Most of these are located in Alaska, where eruptions occur virtually every year. Others are located throughout the west and in Hawaii (see our Volcano Activity Map for their locations).

What are the four types of tectonic plate movements?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform.
What are the four types of plate movements that can cause earthquakes?
There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction.What is the name of where two tectonic plates meet?
THE SPACE WHERE TWO TECTONIC PLATES MEET IS CALLED A PLATE BOUNDARY.What are the three different types of convergent plate boundaries?
There are three types of convergent boundaries each with its own consequences.- Oceanic-Continental Convergence. The first type of convergent boundary is Oceanic-Continetal Convergence.
- Oceanic-Oceanic Convergence. The next type is Oceanic-Oceanic Convergence.
- Continental-Continental Convergence.

What does plate tectonic setting mean?
Tectonic Settings. Plate tectonics is the large scale movement of Earth's crust, and results in a number of distinct geologic settings.
What happens to a continent or a divergent boundary?
The Earth's crust is split into sections called tectonic plates. Divergent boundaries are where two of those plates are moving away from each other. When this happens, magma rushes up to fill the gap, creating brand new crust. Plates can be separated into two types: oceanic and continental.What tectonic plate is Mount St Helens on?
Mount St Helens is on the plate boundary between the Juan de Fuca plate and North American plate.What type of plate boundary is Mauna Loa on or near?
The Mauna Loa is a shield volcano because it's spread out with gentle slopes instead of steep sides. The Ring of Fire is located around the Pacific Plate. It is when plate boundaries surrounding the pacific plate have volcanoes.
