Quickly!!!!-what are the positives and negatives of tectonic plate movements?
Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός “pertaining to building”) is a scientific theory which describes the large scale motions of Earth’s lithosphere. It is vital for the existence of life on earth because of the role that it plays in the global cycle that maintains the balance of carbon between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere.[citation needed] The theory builds on the older concepts of continental drift, developed during the first decades of the 20th century by Alfred Wegener, and seafloor spreading, developed in the 1960s. The lithosphere is broken up into what are called tectonic plates. In the case of Earth, there are currently seven to eight major (depending on how they are defined) and many minor plates (see list below). The lithospheric plates ride on the asthenosphere. These plates move in relation to one another at one of three types of plate boundaries: convergent, or collisional boundaries; divergent bou
