AICE Marine Science Unit 2: Ocean Floor and the Coast 100% Correct tectonic processess - Correct Answer ️️ -movements of the lithosphere resulting in volcanoes, hydrothermal vents, earthquakes, tsunamis, mid-ocean ridges and ocean trenches theory of plate tectonics - Correct Answer ️️ -states that the Earth's crust and upper mantle are broken into plates (huge rock slabs) that move according to convection currents in the earth's mantle in different directions and at different ra...

What is Geology "Earth knowledge" -Scientific study of our planet -Earth's history -Earth's composition -Earth's internal structure -Earth's surface features Sustainable Development Earth is a "spaceship" with limited resources and a delicate life-support system. "Sustainable Development": Current generation must ensure hospitable planet for future generations. The Roles of Geologists -Find and manage NATURAL RESOURCES -Understand Earth processes well enough to ...

Mttc Integrated Science Secondary (Earth And Space Sciences) Elaborated Questions And Answers Theory of Plate Tectonics - CORRECT ANSWER-A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithos...

Plate tectonics theory that explains the: - movement of the continents - changes in Earth's crust caused by internal forces Plates rigid blocks of crust and upper mantle - move along the hot upper mantle - make up the lithosphere Brainpower 0:05 / 0:15 Divergence - 2 plates move away from each other - hot mantle rock rises - creates new sea floor - creates new oceanic crust (2-10 cm per yr) -Mid-Atlantic Convergence - crust collides with another oceanic plat...
