Explosive eruptions tend to build up composite volcanoes.
A composite volcano evolved over tens of thousands of years as a result of several eruptions. The composite volcano is built up through eruptions, layer by layer, until it reaches heights of thousands of meters. Lava may have formed some layers, while ash, rock, and pyroclastic flows may have formed others. A composite volcano can also accumulate significant amounts of thick magma, which can clog up inside the volcano and force it to erupt violently.
Composite Volcano are fueled by a conduit system that accesses a magma reserve deep within the Earth. This magma can erupt either from a sizable core crater at the volcano's summit or from a number of vents scattered throughout the flanks of the composite volcano.

Although the question is incomplete because there is no map attached to answer it, we can say that the top countries in PISA scores are China and Singapore. Educational practices and values at school and at home, not to geography, genes, or immigration represent the reasons why these countries are at the top. This means that the family education system and the public school system of these countries emphasize the children's formation since the family environment and later, in the optimal level of education in their respective school systems.
The PISA system or Program for International Students Assessment is an international examination applied every three to teenagers (15 years-old), evaluating subjects such as science, mathematics, and reading.
