The Changing Earth

by: Savannah Zhou

Our Changing Earth

  1. Our earth and the world we live in is always changing. Constantly. Beneath our feet, something is stirring; above our heads objects are moving. In a million years, our earth won't look how it is now. And our world today, looked different from what it did million of years ago.

The Asthenosphere

  • What is the asthenosphere?
  • What is it's relationship with the tectonic plates and the continental and oceanic crust?

The Lithosphere

  • What is the lithosphere?
  • What connections does it have to the tectonic plates, continental and oceanic crust, and (possibly) the asthenosphere... (most likely)?

What is the Plate Tectonic Theory?

  • What causes the movement?
  • What evidence is there to better understand this theory?

Boundaries

Divergent Boundary

  • What is a divergent boundary?
  • What are the differences between land and in the sea?

Transform Boundary

  • What is a transform boundary?
  • What evidence describes a transform boundary is occurring?

Convergent Boundary

  • What is a convergent boundary?
  • What are all types of convergent boundaries?
  • What evidence best describes a convergent boundary is occurring?

Beneath Our Feet

Hot Spots

  • What are hot spots?
  • How do they occur?
  • Famous hot spots - Old Faithful in Yellowstone National Park and the Hawaii hotspot

Magnetic Reversal

What is a Magnetic Reversal?

  • What is magnetic reversal?
  • How can records of magnetic reversal show how plates move apart?
