PPT-What are the FOUR (4) WAYS our Earth’s PLATES MOVE?

Plates can move apart Plates in the middle ocean often move apartDIVERGE Plates in the middle ocean often move apartDIVERGE The middle of our ocean has the thinnest crust and THATS mostly where NEW Earth comes from. - 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.. Things to Know. What do the layers of the Earth look like?. Check the following terms and definitions to see if they are in your journal.. Layers of the Earth. Inner core. – the solid inner core of the Earth. Pressure makes the iron found there a solid mass. . 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. What is Geology. Geo. - Earth. Ology. is the study of. This activity will help us study the earth by learning what it is made of and how it can be changed. 4 layers of the Earth. Crust. Mantle. Inner core. What is a capacitor?. 2 parallel conducting plates, separated by an insulator. Insulator prevents the capacitor plates from sparking a discharge to each other. Step one: Charging. When the switch is closed, electrons. What can you see in the night Sky?. Moon- the earth’s only natural satellite. Satellite- is a body that orbits a planet. Planet- an object that orbits the sun. 5 are visible from earth without telescope- mercury, Venus, mars, Jupiter, and Saturn. plates meet. In what ways do the plates move? . 3 types of plate movements we need to know: . Convergent: . Plates move together. Can be split into destructive (oceanic and continental crust) and collision (continental and continental) . Crust. Mantle . Core. The Crust. Hard , solid, and strong. Cooler than other layers. Thinner beneath the oceans and made of basalt. Thicker beneath the continents and made of granite. The Mantle. Composed of two layers: the upper mantle and lower mantle. 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.. Tectonic Map of the World. A tectonic plate is like the hard shell on a boiled egg that has been cracked into . • Different types of rocks make up Earth's surface . NOW, you will learn . • About the different properties of Earth's layers . • About the plates that make up Earth's outermost layers. Plate Tectonics (Page 7). • 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 .
