Plate tectonics project
Transcript of Plate tectonics project
The three types of evidence are landforms, fossils, and climate. 1 The evidence from landforms are the shapes of the continents seemed to fit together. Mountain Ranges and other features are also lined up. 2 Fossils evidence from one contintent matched fossils from other continents. 3 The evidence from climate is that Wegener, the creator of the study of continetal drift, looked at certain areas on Earth and their climates. He noted that the fossils he found on certain sections of Earth didn't match the current climate.
Seafloor spreading-"is a process that occurs at mid ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves awayrom the ridge."
Who discovered seafloor spreading?
Seafloor Spreading was a hpothesis proposed by the American Geophysicist, Harry H. Hess.
What is the theory of plate tectonics?
Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other, like slabs of ice on a lake.
Who created the hypothosis of continental drift
Alfred Wegener was the creator of continental drift. The first comprehensive theory of continental drift was suggested by the german meteorologist Alfred Wegener in 1912 the hypothesis asserts that the continent consist of lighter rocks that rest on heavier crystal material similar two the manner and which icebergs float on water."
How does seafloor spreading help scientists to explain continental drift?
"Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed though volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics."
Plate Tectonics Project
Explain seafloor spreading
What evidence (3 types) did scientists use to prove continental drift? Explain.
Describe the three types of plate boundaries that exist.
divergent boundary- occurs when two tectonic plates move away from each other."
Continental drift is a theory that explained how continents shift position on Earth's surface.
convergent boundary- the impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain.
transform plate boundary-"two plates sliding past each other."
