Volcanoes and Plate Tectonics

In class, 6b was assigned to read an article about volcanoes and boundaries, and answer some questions that where included in the sheet. I took notes in my notebook and answer the questions in this post. These are some of the questions and their answers:

 What symbols are used to represent volcanoes? (There was a specific map on the page we had to answer this question with.)
  Active volcanoes are showed as a triangle on the map, but they only show the active ones.
What other symbols are shown on the map?
If I look close, I can see that they used a black and thick line to represent plate boundaries, and they also named the continents.
Where are most of Earth's volcanoes formed?
From the information I read, and can see on the map, they mostly form near borders of the plate boundaries.
Observing, what regions have a large number of volcanoes?
From my point of view, Asia has a lot of volcanoes near the borders, North America has an okay amount also including South America, in Europe I can see a small but still some amount of volcanoes, and last Africa has few around the plate tectonic.
What is a volcano?
A volcano is a sculpture of rock/sediment and magma that is produced by the heat and materials from the upper mantle.
There might have been some more questions, but I thought these were the best ones to share with you. I have learned a lot about volcanoes only through a 4 paged packed and hope it will help me in life.
