Try these first

1. 1.

   What are mid-oceanic ridges?

   Hint

   Think about where tectonic plates move apart.

2. 2.

   What process occurs at mid-ocean ridges?

   Hint

   Consider what happens to magma as plates separate.

3. 3.

   What is a mid-oceanic ridge?

   • A type of earthquake
   • A divergent boundary under the ocean
   • A volcanic island

   Hint

   Think about where tectonic movements occur in the ocean.

4. 4.

   True or False: Mid-oceanic ridges create new oceanic crust.

   • True
   • False

   Hint

   Consider what happens when tectonic plates move apart.

5. 5.

   Evaluate the role of mid-ocean ridges in global tectonic activity and marine biodiversity.

   Hint

   Consider the interconnection between geological processes and biological environments.

6. 6.

   How might understanding mid-ocean ridges change our predictions regarding future seismic activities?

   Hint

   Think about how past behaviors can inform future predictions.
