So where do we find earthquakes and volcanoes…is it in the same place???

Title: So where do we find earthquakes and volcanoes…is it in the same place???

L.O: To know where we find earthquakes and volcanoes on a global scale and to understand their distribution…

Key terms:

Earthquakes

Volcanoes

Distribution

Plate Boundaries

Convection currents

Lesson Starter: Task 1: The Plate Tectonic Dance…Can you show you know your plate boundaries with your dance skills?

Main development: So where do we find volcanoes and earthquakes?

Image result for map distribution volcanoes and earthquakes

Task 2: In pairs look at the above map and try to list the following:

  1. The similarities between volcanoes and earthquakes distribution
  2. Any differences between their distribution
  3. The main areas of the world where we find each of them
  4. The most active plates

Key Exam style question….

Q. Describe the pattern of earthquakes and volcanoes (3marks)…Use your framework below to help you with your response

Task 3: Why do we find earthquakes and volcanoes in the same places???

Its simple…volcanoes and earthquakes are result of movement in the tectonic plates. Earthquakesvolcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries in zones that may be anything from a few kilometres to a few hundred kilometres wide.

 

The four plate boundaries…Destructive, Conservative, Constructive and Collision (we have already TEVED these in our previous lesson on plate boundaries so we know where we find earthquakes and volcanoes and why)
Image result for blank diagrams plate boundaries

Importantly – we know that earthquakes happen at all the plate boundaries as any movement in the crust results in an earthquake…

Using the blank map below of the earth’s plates and different types of movements, can you identify where we would find volcanoes as a result of the type of plate movement taking place on the boundary…Once identified give some annotation around your map as to why we find volcanoes in the location….

Task 4: Plenary – Review: Watch the below clip just to make sure you fully understand now everything about the plate tectonic theory for your assessment in the next few weeks…
