Year 9 Tectonics Feedbcak

Reorder the following to explain how destructive plate boundaries form earthquakes and volcanoes.

• The heavier oceanic plate subducts beneath the lighter continental.

• The risen magma will build in the crust and eventually explode in an eruption.

• Where the two plates subduct, friction is created.

• Also, the subducted oceanic plate will melt in the mantle and rise up.

• This friction builds pressure which is released in sudden shaking, an earthquake.

Categories the following into opportunities and challenges of tectonic hazards.

Groups:

(a) Opportunities

,

(b) Challenges

• Death and injury

• Loss of tourism

• Businesses destroyed

• Jobs in farming and tourism

• Geothermal enegry is cheap

• Homelessness

(c) Planning

• Add rubber to buildings as a shock absorber

• Build buildings out of steel - strong and flexible

• Tiltmeters monitor bulging

• Run drills

• Isolate buildings from their base

• Understand the plate boundaries

• Education

• Train emergency services

What is a primary effect?

• The initial result of an event, caused by the event.

• The knock on impacts of an event.

What is a secondary effect?

• The initial result of an event, caused by the event.

• The knock on impacts of an event.

Finish the sentence. Primary effects like ​ (a)   can be worse than secondary effects like ​ (b)   as a country can take longer to ​ (c)   . For example, ​ (d)   took over 10 years to recover from its ​ (e)   in 2015.

• building collapse
• loss of tourism
• recover
• Nepal
• Italy
• earthquake
• volcano
