what is the meaning of
- tectonic plate
- penetrate
Dear Student,
@ imbaai,
Correct answer! Keep posting!
@ medota,
Your friend imbaai have given absolutely correct definitions for both the terms. I would like to explain tectonic plate in easier way as follow:
The two sub-layers of the earth's crust (lithosphere) that move, float, and sometimes fracture and whose interaction causes continental drift, earthquakes, volcanoes, mountains, and oceanic trenches is known as tectonic plate.
Main features of tectonic plates are as follow:
The Earth's surface is made up of a series of large plates.
These plates are in constant motion travelling at a few centimetres per year.
The ocean floors are continually moving, spreading from the centre and sinking at the edges.
Convection currents beneath the plates move the plates in different directions.
