Y9 Mount Merapi Lesson 2

Y9 Mount Merapi Lesson 2

Today we will...

Make predictions using data

Evaluate the methods of reducing the effects of volcanoes.

Answer an exam style question.

Multiple Select

At which two plate boundaries do volcanoes occur?

• Constructive

• Destructive

• Conservative

Multiple Choice

What causes volcanoes at constructive plate boundaries?

• Two plates come together, one is sub ducted underneath the other and turns into magma. This rises to the surface and erupts to form a volcano.

• Two tectonic plates are moving apart, this causes magma to rise in the through the gap in the tectonic plates and erupt at the surface to form a volcano. When the lava cools it forms new land.

Multiple Choice

Where is our Volcano case study Mt Merapi located?

• Phillipines

• Iceland

• Indonesia

• Australia

Open Ended

Describe one positive of living near a volcano.

Open Ended

Describe one primary and secondary effect of living near a volcano.

Volcano Case Study: Mt Merapi, Indonesia.

Today we will...

Make predictions using data

Evaluate the methods of reducing the effects of volcanoes.

Answer an exam style question.

Open Ended

Recap: Describe the location of Mount Merapi. Using compass directions, including the continent, country, Island and type of plate boundary.

Multiple Select

Which of the following strategies of reducing the effects of volcanoes are classed as prediction?

• Use earth banks to stop lava approaching

• Monitor earthquake activity

• Send early warning messages.

• Measure water near the volcano to check for more gases in the water than usual

Multiple Select

Which of the following strategies of reducing the effects of volcanoes are classed as protection?

• Use explosives to divert lava flow

• Use satellites to detect temperature changes in the volcano

• Use earth banks to stop lava from approaching homes

• Evacuation Plans

Multiple Select

Which of the following strategies of reducing the effects of volcanoes are classed as planning?

• Limit people building in certain areas

• Use instruments to measure how much gas is coming out of the volcano

• Use high tech equipment to check if the magma levels are rising.

• Evacuation plans in the event of a predicted eruption

Can we accurately predict if an eruption is going to happen?

Can you be a volcanologist in the making?

How does a Volcano Change Shape?

• - Pressure builds up in the magma chamber

• - Forces the sides of the volcano to expand

• - Scientists use satelites to check the shape changes from space.

Skip forward 20years from now, and you are working as a Volcanologist in Indonesia. It is your job to protect the people living near the volcano. Can you predict how the volcanic will erupt, can you save the local population?

Multiple Choice

Using the data we have just explored, what kind of eruption do you predict will happen? How would you advise the mayor to act?

• Do nothing

• Advise the Mayor that the people living in Sleman village must be evacuated

• Advise the Mayor that the volcano will erupt, but it will not damage any towns

• Advise the Mayor that the all people living in Sleman region must be evacuated

Small Eruption

• If you selected - Advise the Mayor that the volcano will erupt, but it will not damage any towns - WELL DONE!!

• The eruption did not damage any major towns, but two tourists who did not listen to the Mayors warnings had to be rescued

Multiple Choice

Using the data we have just explored, what kind of eruption do you predict will happen? How would you advise the mayor to act?

• Do nothing

• Advise the Mayor that the people living in Sleman village must be evacuated

• Advise the Mayor that the volcano will erupt, but it will not damage any towns

• Advise the Mayor that the all people living in Sleman region must be evacuated

Large Eruption

• if you selected - Advise the Mayor that everyone in the Sleman Region needs to be evacuated - WELL DONE, you have just saved thousands of lives!!

• The violent eruption casued huge amounts of damaged many of the major towns in the as hot rocks and thick ash clouds rained down on the area. Lava flowed down drom the volcano destroying everything in its path.

Poll

Which method of protection do you think is the most effective.

• Use explosives to divert lava

• Build earth banks to stop lava from getting to buildings

• Design strong buildings

• Spray water to cool the lava

Open Ended

For the method you chose in the previous question, explain your reasons for why you believe it would be the most effective method. (Explosives, earthbanks, water, design strong buildings)

Poll

Which method of planning do you think is the most effective.

• Evacuation plans

• Exclusion and safe zones set up

• Volcano drills to prepare people for what to do when an eruption happens

• Early warning through good communication methods

Open Ended

For the method you chose in the previous question, explain your reasons for why you believe it would be the most effective planning method. (Evacuation, exclusion and safe zones, eruption drills, communication)

Now it is time to have a go at an exam style question :-)

I have shared a google document with you in the classroom, can you please go and open then, and spend the rest of the lesson writing a response to this question.
