Tectonic landforms on large and small bodies in the solar system are as ubiquitous as impact craters. Since the 1960s, an armada of exploratory spacecraft have identified widespread evidence of tectonism on all the terrestrial planets, most of the satellites of the outer planets, and on a number of asteroids.

The field of planetary tectonics extends the concept of tectonics to studying non-terrestrial bodies such as other planets and moons: Watters, Thomas R. The words tectonics and architecture are derived from the same Greek root, and tectonics is defined as the architecture of the Earth's crust. Rather, best practice in risk assessment is to identify a suitably. Geologists (as distinct from architects) may define tectonics as "the architecture of the Earth's crust" - UK law has incorporated 2009/31/EC CCS Directive (Section 4.1.3.2) mainly through the. Other fields of tectonic studies Salt tectonics Most of the deformation in the lithosphere is related to the interaction between plates at or near plate boundaries. Convergent and divergent boundaries are also the site of most of the world's volcanoes, such as around the Pacific Ring of Fire. Convergent and transform boundaries are responsible for most of the world's major ( M w > 7) earthquakes. There are three main types of plate boundaries: divergent, where plates move apart from each other and new lithosphere is formed in the process of sea-floor spreading transform, where plates slide past each other, and convergent, where plates converge and lithosphere is "consumed" by the process of subduction.
The lithosphere is divided into separate "plates" that move relative to each other on the underlying, relatively weak asthenosphere in a process ultimately driven by the continuous loss of heat from the Earth's interior. That meaning, all the land was stuck together in one big thing.ī.In plate tectonics, the outermost part of the Earth known as the lithosphere (the crust and uppermost mantle) act as a single mechanical layer. similar rocks found in different continents.Ħ.) Wegener's theory of continental drift was not accepted by all scientists.Ī.) What was the main counterargument against Wegener's evidence?ī.) What information did Wegener not have that would have strengthened his argument?ħ.) It is thought that all the continents used to be part of one super-continent.ĪNSWER: The super continent, pang ea was formed before the tectonics plates shifted to its current locations. Make sure you label crust, subduction zone, magma, volcano, and the direction of plate movement.ĥ.) What are four pieces of evidence Alfred Wegener used to support his theory of continental drift? Earth's tectonic plates are rigid slab's of rock.Ĭ.) Which is the stronger force behind plate movement?Ĥ.) Volcanoes are usually found near subduction zones.Ī.) Why do you usually find volcanoes near subduction zones?ĪNSWER: Because one of the plates get pushed up creating a volcano or mountain.ī.) Draw a diagram to assist your explanation. 1.) Draw a diagram of Earth that labels its mechanical layers on one side and its composition layers on the other side.ĪNSWER: I TURNED IN PAPER COPY BECAUSE IT HAD TO BE DRAWN.Ģ.) Fill in the table with information about the different types of boundaries.ģ.) There are alternate explanations for the forces behind plate movement.ĪNSWER: A tectonic plate motion due to higher densities.ī.) What is "slab-push"? Give one example of a slab-push structure.ĪNSWER: It is a plate tectonics's movement.
