  • TOPIC FOR TODAY IS SEAFLOOR SPREADING
  • Good day to you all, I am justine myar today I will explain on how SEA FLOOR SPREADING happens. Dr. Guillermo is with us to explain.
  • Hello, I'm Dr. Guillermo, let's join us on how SEA FLOOR SPREADING happens.
  • DR.GUILLERMO HOW SEAFLOOR SPREADING HAPPENS ?
  • HOW SEAFLOOR SPREADING HAPPENS
  • Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
  • Oh my God and then?
  • HOW SEAFLOOR SPREADING HAPPENS
  •  The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
  • Topic for today is how seafloor spreading happens.
  • WHAT CAUSES SEAFLOOR SPREADING?
  • Seafloor spreading creates new oceanic crust at a mid-ocean ridge. When this new material reaches the end of the plate and comes into contact with another plate, whether continental or not, a convergent or a transform boundary will occur.

  • WHERE IS SEAFLOOR SPREADING TODAY?
  • OMG What happens here? Where is seafloor spreading today?
  •  The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
  • HOW IS SEAFLOOR SPREADING EXPLAINED AND PROVEN?
  • . When this new material reaches the end of the plate and comes into contact with another plate, whether continental or not, a convergent or a transform boundary will occur.creates new oceanic crust at a mid-ocean ridgeSeafloor spreading 
  • What causes seafloor spreading?
  • today along the oceanic ridges. The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'
  • today along the oceanic ridges.
  • Seafloor spreading is the mechanism by which new seafloor lithosphere is constantly being created at mid-ocean ridges. This theory, introduced by Harry Hess, was proven as patterns of magnetic field polarity preserved in seafloor basalt and by age dating of the rocks.
