A whimsical look at the layers of the Earth and its atmosphere
Not to scale, but fun to look at nevertheless! By Rachel Ignotofsky, available as a print too.
Study calls for changes to geology books in light of new simulations
The new models have revealed that ancient events may have left deep 'scars' that can trigger changes at the surface – including the folding, breaking, or flowing of the crust in tectonic plates.
A Simple Wilson Cycle The Opening and Closing of An Ocean Basin The Wilson cycle begins in Stage A with a stable continental craton. A hot spot (not present in the drawings) rises up under the craton, heating it, causing it to swell upward, stretch and thin like taffy, crack, and finally split into two pieces. This process not only splits a continent in two it also creates a new divergent plate boundary. Stage B - the one continent has been separated into two continents, east and west, and a…
Petroleum Systems in Extensional Regimes
Areas of extension are afﬁliated with horizontal divergent stress and are found in association with constructive or passive plate boundaries and in intra-plate settings. Thus, extensional stress regimes either are associated with subsidence and basin formation (in intra-plate settings) or characterise active break-up of continents (along constructive or passive margins). Although the conditions for development of petroleum systems in areas of active spreading may be meagre, the remnants of…
How Mountains are Formed - Lesson
Students investigate how mountains are formed. Concepts include the composition and structure of the Earth's tectonic plates and tectonic plate boundaries, with an emphasis on plate convergence as it relates to mountain formation. Students learn that geotechnical engineers design technologies to measure movement of tectonic plates and mountain formation, as well as design to alter the mountain environment to create safe and dependable roadways and tunnels.
It was hard to find a hands on layers of earth project that was age appropriate. I took a paper plate and colored it with crayon. A paper cup makes the perfect circle in the center. #science #layersofearth
