Plate boundaries cover 15% of the Earth’s surface and cover a spatial range that spans from a single fault system to diffuse regions of deformation sometimes with stranded microplates [e.g., Gordon and Stein, 1992; Stein and Sella, 2003; DeMets et al., 2010; Kreemer et al., 2014].
10 Φεβ 2015 · This scriptum to a lecture series at ETH Zürich summarizes the fundamental concepts and observations that allow first insights into principles of plate tectonics.
The edges of the plates are called plate boundaries. The Earth has 7 major plates (Africa, Antarctica, Australia, Eurasia, North America, South America and Pacifica) and several minor ones (Adria, Arabia, Caribbean, Nazca, Philippines and others). Most of the plates are composed of continental and oceanic lithosphere. These plates
21 Νοε 2020 · Expressions of plate tectonic interactions at the Earth’s surface also provide critical insight into the machinations of our planet’s inaccessible interior, and allow postulation about the...
Intense geologic activity occurs at plate boundaries where plates: Move away from one another. Move past one another. Move towards one another. The theory of plate tectonics is widely accepted by geologists today because it explains so many of the Earth’s features.
The plates move about at a rate of a few cm per year. • The three types of plate boundary are: divergent plate boundaries (MORs and continental rifts), convergent plate boundaries (subduction zones and continental collision), transform boundaries (that connect one type of boundary to another).
