What kind of tectonic collision produces volcanoes?
oceanic-continential
Why do so many of earths volcanoes occur along plate boundries?
Volcanoes often occur along plate boundaries because the movement of tectonic plates leads to the formation of subduction zones, where one plate is forced beneath another. This process creates intense heat and pressure, causing magma to rise to the surface and form volcanoes. Additionally, divergent plate boundaries can also create volcanic activity as magma reaches the Earth's surface through rifts in the ocean floor.
What is the name given to the area where volcanoes often occur because convection in the earths mantle produces a column of magma that rises into the crust?
hotspots
How are volcanoes on oceanic rocks different from those on the continent?
Volcanoes on oceanic rocks are typically associated with divergent plate boundaries and hotspots, resulting in primarily basaltic lava that produces shield volcanoes and low-viscosity eruptions. In contrast, continental volcanoes often occur at convergent plate boundaries and can produce a wider variety of rock types, including andesite and rhyolite, leading to more explosive eruptions and stratovolcanoes. The geological setting and composition of the magma influence the eruption style and the landscape formed by these volcanoes.
What 2 types of volcanoes are there?
There are three. From smallest to largest, they are: Cinder Cones, Composite Volcanoes (also called Strata Volcanoes), and then Shield Volcanoes.
What boudaries can produce volcanoes?
Plate (subductive).
What kind of tectonic collision produces volcanoes?
oceanic-continential
What kind of volcano produces the most violent type of activity?
volcanoes
What layer produces the magma that cause seafloor spreading and volcanoes?
the upper mantle
Volcanoes can erupt due to the blank of plates that produces heat for the rock to melt?
Subduction.
Is pahoehoe lava only found in Hawaii?
No. Many shield volcanoes produces pahoehoe.
How much sulphur dioxide is produced in Iceland?
Sulphar Dioxide is the gas that volcanoes release. How much Iceland produces depends on how many and how often volcanoes erupt.
How are the mountains that are formed by subduction diffrent from mountains formed by continental crusts converging?
Subducting crust produces volcanoes and a narrow range of mountains (like the Andes). Continental convergence does not produce volcanoes and produces a wider range of mountains (Rockies or Himalayas).

What is called when lava from undersea rift zones produces volcanoes and mountain chains?
mid ocean ridges
Do volcanoes strike in the same place twice?
A volcano is a geologic feature, not an event. An event in which a volcano produces lava or ash is a volcanic eruptions. Virtually all volcanoes will erupt multiple times.
What were the US boundaries in 1803?
the eastern and western boudaries of Patagonia is ''fagtopolis''.
