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.
A.

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.
  • Where are earthquakes most likely to take place?

    Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates.
  • Where do most of the world's earthquakes and volcanoes occur?

    At diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates. We almost never see these volcanoes, because most of them are located on the sea floor.
  • 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).
B.

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.
  • Where can Stratovolcanoes be found?

    Stratovolcanoes are also commonly called composite volcanoes. Mt. Fuji in Japan is an example of a stratovolcano. Stratovolcanoes are most found commonly along subduction zones, which are boundaries between two tectonic plates where an oceanic plate is sinking into the mantle beneath another tectonic plate.
  • What is the tectonic setting of Mt St Helens?

    Mt St Helens is a major stratovolcano in the Cascades Range, all of which have formed as a result of the ongoing subduction of the Juan de Fuca tectonic plate beneath the western coast of North America.
  • Where are composite volcanoes found in the world?

    Some of the most conspicuous and beautiful mountains in the world are composite volcanoes, including Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Shasta in California, Mount Hood in Oregon, and Mount St. Helens and Mount Rainier in Washington.
C.

Where can you find the Ring of Fire?

Pacific Ocean
  • Where can you find the Ring of Fire?

    Pacific Ocean
  • Where do most of the world's earthquakes occur?

    Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates.
  • Where do most volcanoes on land occur?

    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.
