Question

Which is the only plate boundary that doesn’t involve magma?

Answer 1

The plate boundary that doesn't involve magma is the transform plate boundary .

magma is formed at three main plate-tectonic settings: divergent boundaries (decompression melting), convergent boundaries (flux melting), and mantle plumes (decompression melting).

As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary . ... This is known as a transform plate boundary.

Answer 2

The only plate boundary that doesn't involve magma is transform boundary.

Step-by-step explanation:

Transform boundary can be regarded as a strike-slip boundary and can be explained as fault along a plate boundary.
