The '''Borborema Plateau''' ([[Portuguese language|Portuguese]] ''Planalto da Borborema'', also known as the ''Serra da Borborema'') is a plateau in northeastern [[Brazil]] which extends across the states of [[Pernambuco]], [[Paraíba]], and [[Rio Grande do Norte]].<ref name="brit"/> The plateau is the northeasternmost portion of the [[Brazilian Highlands]] and is the most relevant watershed of its region. It ranges approximately {{Convert|400|km|mi}} from north to south and {{Convert|200|km|mi}} from east to west.<ref name="w"/> More than 100 rivers originate from the plateau, including the [[Moxotó River|Moxotó]], [[Mundaú River|Mundaú]], [[Pajeú River|Pajeú]], [[Paraíba do Norte River|Paraíba do Norte]], [[Seridó River|Seridó]], and [[Una River (Pernambuco)|Una]].<ref name="w"/>

The Borborema Plateau serves as an [[orography|orographic]] barrier, despite its relatively low elevation, against the moist easterly winds of the [[Atlantic Ocean]]. Areas west of the plateau, which make up part of the [[sertão]], are arid and prone to drought. The [[Pajeú River]], the largest tributary of the [[São Francisco River]], originates from the Borborema.<ref name="c"/><ref name="w"/>

== Geology ==
The Borborema Plateau is part of a huge [[Anastomosis|anastomosing]] [[shear zone]]. The plateau is composed primarily of [[igneous]] and [[metamorphic]] rock.<ref name="borb"/>
