Introducing Volcanoes
Background Understanding.
There are broadly speaking, two different types of volcano that exist around the world. All volcanoes can be explosive but not all of them kill people. Additionally, many millions of people live close to or on volcanoes. What is the attraction?
Task 1 - To understand why some volcanoes are more dangerous than others, we must find out a little more about the mechanisms behind each.
Using this website from the BBC, complete the fact finding task on the first page of the worksheet.
Task 2 - Now that we have understood the two categories of volcanoes, we must now switch our attention to finding out why many millions of people around the world live close to active volcanoes, in particular, strato or compositive volcanoes (the most deadly).
Using this link, complete the tasks on the second page of the worksheet.
Task 3 - Ok, so you can see the benefits of living close to volcanoes for all those people. However, don't forget that sometimes people live there simply because they cannot afford to go anywhere else. Many countries with volcanoes are very poor or by nature are islands meaning that the resident popualtion has no alternative to stay and live with threat. So, the next question is how do scientists try to warn people if a volcano is about to go off?

Case Study - Back To The 80's!
Volcanic Eruption - Colombia 1985
Objective: To find out what made the 1985 eruption of Nevado del Ruiz so deadly and why people lived so close to this volcano.
Task 1 - Using the Google Map below, describe the location of the Nevado Del Ruiz volcano and link its existence to the plate boundaries in this part of the world. Take a 'street view' tour around the crater too using the embedded map below.
Task 2 - Study the following PowerPoint Presentation carefully.
Use the resources contained within it to build up a case study of the eruption using the structure on the last slide as a guideline. Your major resource here is going to be the video documentary below.

What does Armero Look Like Today &
Why Did People Live So Close to the Volcano?
From the work you have completed on Nevado del Ruiz 1985 eruption, you have discovered that many people lived close to the flanks of this dangerous volcano.
But what does the area look like today? Click here to be taken to a map the shows the area that was once the town of Armero. Look carefully and you will see the outline of the blocks or roads and remains of the houses that were destroyed in by the lahars.
Spend a little time looking at the embedded 360° images below to see what the town now looks like in 2022.

Task 3 - Read this article from Wikipedia, and complete the worksheet below.
How is this tested in a real Geography exam?
Click on the links below to access a Paper 1 where there is a 25 mark question on volcanoes, including a 7-mark question about why people live close to them. You will also need the resource booklet to answer one of the structured questions.
Examination Paper - Answer question 4
Resource booklet - You will need figure 4.2
Stop Check - Hot Spot Volcanoes
|
Do you know what a hot spot volcano is?
Check out the video to the right hand side to see why we sometimes get volcanic activity well away from the major plate boundaries. Create a mini fact sheet that explains the formation of hot spot volcanoes and give a global example. |
