• Activity 1: Read Me! Understand Me!

  1. Read the three plate boundaries description and characteristics

  2. Understand what you are reading
• Plate boundaries


  The lines at the edges of the different pieces of the lithosphere
• Lithospheric plates


  Moving due to the convection current in the Earth's interior
• Lithosphere


  Made up of the crust and upper part of the mantle
• Types of crusts


  • Continental crust (thicker but less dense)
  • Oceanic crust (thinner and denser)
• Plate Tectonic Theory


  The Earth's lithosphere consists of the crust and upper mantle that move slowly and constantly over time
• Plate boundaries


  • Divergent
  • Convergent
  • Transform fault
• Divergent boundaries


  Plates separate and move apart in opposite directions forming new lithosphere (young seafloor) at mid-ocean ridges (seafloor spreading) or rifted continental margins (rift valley)
• Convergent boundaries


  Formed when two plates move toward each other, with the oceanic plate bending downward at the subduction zone. Occurs in two oceanic plates (convergent boundary) and continental plate-oceanic plate (convergent boundary). Older oceanic plate sinks, while continental plates collide and buckle up forming mountain ranges.
• Transform fault boundaries


  Plates sliding past or slipping past each other
• Divergent boundary


  • Boundary between South American plate and African plate
  • Pacific Plate and Nazca Plate
  • North American Plate and Eurasian Plate
• Convergent boundary


  • Boundary between Eurasian plate and the Philippine plate
  • Nazca Plate and South American Plate
  • Pacific Plate and Australian Plate
• Transform fault boundary


  • San Andreas Fault

• What I Can Do
• Divergent boundary


  Two plates moving away from each other
• Convergent boundary


  Plates moving toward each other
• Three types of convergent boundaries

  • Convergent boundary which forms volcanic island arc
  • Convergent boundary forming a continental volcanic arc
  • Convergent boundary wherein there is no subduction
• At the convergent plate boundary, the older crust is melted by subduction
• The East African Rift is an example of a divergent boundary
• The Himalayan mountain range of India was formed at the convergent boundary
• The San Andreas Fault is an example of a transform fault boundary
• Philippine islands were originated from convergent boundary
• The boundary between two plates moving together is called a convergent boundary
• Movement of the plate boundary causes shaking of the Earth's surface called earthquakes
• Lithosphere


  Earth's crust and upper mantle
• Mid-ocean ridge is formed between the diverging oceanic plates
• The Caribbean plate and North American plate form a convergent boundary
• Magma and molten rocks are other terms for the same thing
• Plates move apart at divergent boundaries
• Plates slipping past each other form a transform fault boundary
