Destructive Plate Margin – Tectonic plate margin where two tectonic plates converge or come together

To remember the meaning of the term Destructive Plate Margin, use the following mnemonic:

She destroyed (destructive) the edge of the plates by banging them together.

There are three types of destructive plate margin:

1. Where two thin oceanic crusts converge in the ocean.
2. Two thick continental (land) crusts converge on land.
3. A thick continental (land) crust and a thin oceanic crust converge where land and sea meet.

Note: There are no such thing as a purely continental (land) tectonic plate. Tectonic plates are mainly so big they vary around their edges or margins and across their surfaces from crusts in the ocean to thick crusts on land.
