22.5.3. Ridge Push

Try these first

1. 1.

   What is ridge push?

   Hint

   Think about the force of something elevated.

2. 2.

   Which ocean feature is primarily associated with ridge push?

   Hint

   Where do you see new oceanic crust being formed?

3. 3.

   What is the primary force behind ridge push?

   • Convection currents
   • Gravity
   • Magnetic forces

   Hint

   Think about the role of elevation and weight.

4. 4.

   True or False: Ridge push is a mechanism that solely causes earthquakes.

   • True
   • False

   Hint

   Consider that many factors influence seismic activity.

5. 5.

   Calculate the approximate plate movement contributed by ridge push if a mid-ocean ridge has an elevation of 2 km and the average gravitational acceleration is 9.8 m/s².

   Hint

   Think about the relationship between elevation and gravitational force applied.

6. 6.

   Discuss the implications of ridge push on coastal communities near mid-ocean ridges. What effects might they experience?

   Hint

   Consider the relationship of geological movement to human infrastructure.
