At spreading ridges, magma is constantly produced through decompression melting as plates move apart, resulting in volcanic activity and the formation of new oceanic crust. This process accounts for the majority of magma production on Earth. The other options listed (transform plate margins, convergent plate margins, and hot spots) all involve other mechanisms for magma generation and are not as prevalent as spreading ridges.
