Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.

At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.

High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."

The oceanic Nazca plate is being subducted beneath the continental South American plate. Which type of plate boundary is this?

marusya05 [52]

<h3>Answer;</h3>

A. continental-oceanic convergent

<h3>Explanation;</h3>

A convergent boundary is a type of boundary where two plates collide and push against one another.
A continental-oceanic convergent is a type of convergent boundary that occurs as a result of subduction. Subduction occurs where a continental plate collide thus resulting to the oceanic plate being pushed underneath the continental plate into the mantle since the oceanic plates are much thinner.
The result is that the oceanic plates melts into hot magma which that burns its way up through the continental plate forming a volcano and also causing earth quakes.
