Trench. Where two tectonic plates converge‚ if one or both of the plates is an oceanic lithosphere‚ a subduction zone will form. When crust is formed at a mid-ocean ridge‚ it is hot and buoyant meaning it has a low density. As it spreads away from the ridge and cools and contracts‚ or becomes denser‚ it is able to sink into the hotter underlying mantle. When two oceanic plates collide‚ the younger of the two plates‚ because it is less dense will ride over the edge of the older plate. The density of

depending on its age‚ and is broken into plates‚ known as the tectonic plates. Within the lithosphere is the crust as a portion of the upper mantle. The crust is the outer most portion of the earth and takes up less than 1% than the total volume of the earth. It is commonly compared to the skin of an apple‚ whereas the apple represents the earth. The temperature of the crust varies from the air on top‚ to upward of 1600 at the deepest parts. The tectonic plates are part of the crust of the earth‚ moving

Archeozoic Era The Archeozoic Era stretches from about 3.8 billion to 2.5 billion years ago. Traditionally‚ the beginning of the Archean is defined to coincide with the oldest rocks discovered. As recent discoveries have pushed back the earliest dated rocks to about 4.0 billion years old‚ the beginning of the Archean has also been pushed back correspondingly. However‚ most texts still continue to date the beginning to 3.8 billion years ago. As the Late Heavy Bombardment (LHB) ended with the Hadean

Evidence gathered by Ewing‚ Tharp and Hess that lead to the theory of plate tectonics was: ⦁ In the early 1950s Ewing‚ with the help of Marie Tharp‚ a cartographer‚ mapped the seafloor using available echo profiles‚ the resulting mapped showed a large canyon that traversed the length of the ridge. ⦁ Hess explains that as new

Several ramifications that probably dont come readily to mind are the effects on the human body‚ thermodynamics and plate tectonics. Without friction‚ many functions of the human body would not work. Procreation would be impossible as friction is necessary for the male orgasm. Digestion would be impossible as the human body uses friction to digest and move food throughout
