Key Concept BEFORE you learned The continents join and break apart The sea floor provides evidence that tectonic plates move The theory of plate tectonics helps explain how the plates move. Our Super-NuovaSeries stirrers, hot plates Super-Nuova is available in two sizes, including controlled stirrdfor applications that THERMO SCIENTIFIC SUPER-NUOVA Microprocessor display maintains User Risk issues and allocation 1 Worlds Apart: EPC and EPCM Contracts: Risk issues and allocation By Phil Loots 1 and Nick Henchie 2 Introduction For many years now it seems that the most desired way f - To be able to explain how mountains are formed . Plate Tectonics . The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle) called tectonic plates. . These plates are in constant motion travelling at a few centimetres per year. This is called continental drift.. Imagine the Earth as a hardboiled egg…………………….. The thin brittle shell is the crust that humans live on.. The thick jelly like white is the deep hot magma beneath the surface.. The yellow yolk is the core of the earth.. What do you think?. Recall. :. Theory of Plate Tectonics…. Plate Tectonics . refers to the movements of plates (large segments of continents and ocean) around the Earth’s surface.. These land masses are seen as a giant . It is difficult for scientists to estimate the exact amount. How do they Move?. Plates move by floating on top of the Upper mantle (Asthenosphere). The plates move in a certain direction based on the flow of magma beneath them. Unit 12.1. These observations lead him to come up with the . ___________________________. A very long time ago (~200 million years) the continents were joined together in a . ___________________. called . 50 cm farther apart in the next 20 years.. Solution . Write an equivalent rate.. Tracking Tectonic Plates. Scientists use lasers to track the movements of tectonic plates. They bounce laser light off satellites and measure the distance from each satellite to the ground. As the plates move, the distance changes. With this tracking system, scientists know exactly how much tectonic plates move each year.. CONTINENTAL DRIFT THEORY. ALFRED WEGENER . proposed all continents . . originally formed from one landmass . . (PANGEA). EVIDENCE OF CONTINENTAL DRIFT:. . 1. Fossilized tropical plants in Greenland. The Theory of Plate Tectonics. Earth’s Lithosphere is broken into many pieces called plates. Plates mover very slowly – only a few centimeters per year. We measure that movement with GPS. But how does it work?. • About evidence for plate movement from the sea floor . • How scientists developed the theory of plate tectonics. Continents change their position over time (Page 14). *Key Concept. BEFORE, you learned . This comprehensive guide delves into the intricacies of UK car number plates, shedding light on their structural significance and the various elements that make them a unique and informative feature on every vehicle. We will delve into everything you need to know about green number plates, shedding light on their significance, benefits, and broader implications for the future of transportation.
