PPT-Sea Floor Spreading Chapter 4

Section 4 Standard S 61 Students know evidence from plate tectonics is derived from the fit of the continents and mid ocean ridges Vocabulary Midocean ridges Sonar Sea floor spreading Deep ocean trench. Comfort is hard to define and is best understood as the absence of discomfort. Perhaps the most remarkable thing about radiant heat is what you won't notice. There are no forced air registers to see. No noise or dust from mechanical blowers. No hot air blowing on you. No hot air collecting at the ceiling, wasting energy. No cold floors to chill your feet. The mild warmth of a radiant floor is a subtle experience and always feels just right.

Mapping of the Ocean Floor. WWII played an important role in mapping of the ocean floor- Why?. They were able to observe and determine the depth of the ocean floor and the features of the ocean floor.. Today you need to know. Explain what evidence there was to support the theory of continental drift – suggested by Alfred Wegener. Explain why the scientific community did not accept his theory. Understand how seafloor spreading provided further evidence that his theory was correct. What You Will Learn. Describe Wegener’s hypothesis of continental drift. . Explain . how sea-floor spreading provides a way for continents to move. . Describe . how new oceanic lithosphere forms at mid-ocean ridges. . Video on Earth 1 million years from now. Theory of Continental Drift. Alfred Wegener . wrote . about his hypothesis of . continental . drift . in the 1900s. .. Continental drift.  is the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations. . Drifting Continents. Sea-Floor Spreading. The Theory of Plate Tectonics. Plate Tectonics. Piecing It All Together. The coastlines of some continents seem to fit. together like a jigsaw puzzle.. Drifting Continents. Subduction. Fun Fact: The tallest mountain in the world is…. Not Mt. Everest (29,028 ft). It’s Mauna Kea in Hawaii! (31,000 ft) . It doesn’t get as much attention because 2/3 of it is underwater.

Sonar (an acronym for sound navigation is a way to use sound . to navigate, . communicate . or detect objects on or under the surface of the water, such . Plate tectonics review. Earth’s lithosphere is divided into large tectonic plates. They are constantly in very slow, motion.. Plate tectonics review. ____________ pushes the tectonic plates apart in sea floor spreading. This causes the motion of the plates..
