This is a theory in geology which explains that the lithosphere
is divided into a number of rigid bodies ( plates). These plates
that interact with another at their boundaries, causing seismic
and tectonic activity along these boundaries.
The structures (for example, bedding, faulting, folding) and
features of the displayed geological units in a region which
have resulted from forces or movements coming from different
Ophiolite: The group of mafic and ultramafic igneous rocks. (Mafic: This is the composition of an igneous rock, which contains ferromagnesian and dark-coloured minerals. Ultramafic: This is the composition of an igneous rock, which has been composed chiefly by mafic minerals).
