Unit 4 Lesson 5 Earthquakes. Unit 4 Lesson 5 Earthquakes. Let’s Focus. What is an earthquake?. Earthquakes are ground movements that occur when blocks of rock in Earth move suddenly and release energy. The energy is released as seismic waves that cause the ground to move.By gaynell

Tectonic plates. By: Hephzibah Olajimi , Aileen Nicole Martinez, Mykah Paul Abi lutz. How tectonic plates move?. Plates move because of the convection currents in the mantle. Earth heats up the materials inside, the molten magma also gets heated up. plates. Indo australian plate.
Tectonic Plates. Plate Tectonics. The lithosphere (crust and upper part of mantle) is broken into 15 pieces called tectonic plates !. The places where the tectonic plates meet each other are called plate boundaries!. CRUST!!!!!. CONTINENTAL CRUST. OCEANIC CRUST. Underlies oceans

Tectonic Plates. The Theory of Tectonic Plates. The theory of plate tectonics is that they move portions of the Earth’s crust, creating different land masses and seas.
Tectonic Plates. By: Jax Cooper. Pangaea. •The Theory of Pangaea Is that 300 million years ago, all the continents were once connected. • The ‘super continent’ idea was not accepted by scientist because Wegner did not have enough proof that this had happed such a long time ago.

Objective: To learn how tectonic plates move and what evidence we have for continental drift. Tectonic Plates. Starter: Word search – rock cycle review. Tectonic plates. The crust is made of about twelve plates . These are like big rafts floating on the semi-molten mantle.
Tectonic Plates. Mrs. Hartman. Tectonic Plates. Definition: Pieces of the lithosphere that move around on top of the asthenosphere (think of the lithosphere like a giant jigsaw puzzle). Popcorn read page 396-397 and look at figure 4. Tectonic Ice Cubes demo. Popcorn read page 398.
Earth Science 9.3 Theory Tectonic Plates. Theory Tectonic Plates. Earth’s Moving Plates. During the 1960s, scientists realized that the theory of sea-floor spreading explained the idea of continental drift. It explained how ocean basins could open and close over time.
