Wegener did not know the mechanism that moved the plates, and his theory was rejected until the 's when scientists studied the ocean floor and found the mid-ocean ridges (sea floor spreading zones). Pangaea -Super continent million years ago. The seven continents were all connected together into one huge land mass. A Model of Seafloor Spreading Purpose: The purpose of this activity is to make a simple model that shows the evolution of oceanic crust through sea-floor spreading. Materials: Model of Seafloor Spreading templates [one with three straight lines and another with striped bands or striped bands with arrows] Colored pencils or crayons.

Title: Model a spreading ocean floor offset by transform faults Subtitle: A model of the transform fault ‘steps’ in oceanic ridges and their magnetic stripes Topic: Making a working model showing how sea floors spread, offset by transform faults. The fully ‘spread’ model looks like this: Age range of pupils: 14 – 19 yearsFile Size: 1MB. Spreading center. Seafloor spreading occurs at spreading centers, distributed along the crests of mid-ocean ridges. Spreading centers end in transform faults or in overlapping spreading center offsets. A spreading center includes a seismically active plate boundary zone a few kilometers to tens of kilometers wide, a crustal accretion zone within the boundary zone where Missing: Dynamical models.

A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate typically has a depth of ~ 2, meters (8, ft) and rises about two kilometers above the deepest portion of an ocean feature is where seafloor spreading takes place along a divergent plate rate of seafloor spreading determines the morphology of the crest of the mid Missing: Dynamical models. Sea Floor Spreading. Seafloor Bathymetry. World War II gave scientists the tools to find the mechanism for continental drift that had eluded Wegener. Maps and other data gathered during the war allowed scientists to develop the seafloor spreading hypothesis. This hypothesis traces oceanic crust from its origin at a mid-ocean ridge to its Missing: Dynamical models.

Fluid dynamic models of the lithosphere‐asthenosphere system are studied. These models provide a basis for understanding driving mechanisms involved in sea floor spreading. The asthenosphere is rep Dynamical models for sea floor spreading - Richter - - Reviews of Geophysics - Wiley Online LibraryCited by: Fluid dynamic models of the lithosphere-asthenosphere system are studied.

Modeling Sea-Floor Spreading Reviewing Content Mid-ocean ridges are long, underwater mountain chains that rise up from the ocean floors. New ocean crust is continually added to Earth along these ridges in a process called sea-floor spreading.

During sea-floor spreading, two tectonic plates move apart, forming a crack in the ocean Size: KB. It outlines the geological, geophysical and petrological observations that characterize extensional systems, and how such observations can guide and constrain dynamic and kinematic models of continental lithosphere extension, breakup and the inception of organized sea-floor spreading.

The book focuses on imaging, mapping and modelling lithospheric extensional systems, at both the regional scale using dynamic models to the local scale of individual basins using kinematic models.

The book teaches the use of a modelling program called STELLA, that can be used to simulate the behaviour of dynamical systems. You can treat the text as an extended user's manual about the capabilities of STELLA.

It appears to be an easy program to by: This report describes how to build a model of the outer km ( miles) of the Earth that can be used to develop a better understanding of the principal features of plate tectonics, including sea-floor spreading, the pattern of magnetic stripes frozen into the sea floor, transform faulting, thrust faulting, subduction, and volcanism.

Next they cut out a round drawing of the earth, added a “fold” tab, folded that all in half, and glued it half of it to the layers, and half to the book page, making a page-within-the-page.

For students who finished early, Katy offered a model of sea floor spreading for them to experiment with for an extra page in their books. Developments in Geotectonics, Volume 2: Geodynamic Models: An Evaluation and a Synthesis presents the concept of sea-floor spreading and the hypothesis of global plate tectonics.

This book provides a basic understanding of the global movements. Organized into eight chapters, this volume begins with an overview of the concept. This diagram provides evidence of seafloor spreading by showing the ages of ocean floor in the Atlantic and eastern Pacific Oceans.

According to the theory of plate tectonics, (from the Greek, tekto, “builder”), the Earth’s crust is broken into many slowly moving plates. Sea floor spreading occurs at the mid-ocean ridge where two plates are moving away from each other. Here, magma rises up fromMissing: Dynamical models.

Two major sea‐floor spreading episodes were revealed with different dynamic mechanism, separated by a remarkable tectonic‐sedimentary event near 25 Ma.
