Tectonic Hazards Flashcards
What’s The 1st Layer Of Earth And What Characterise Does It Have?
- Inner Core
- Its 5,500 Degrees
What’s The 2nd Layer Of Earth and What Characteris Does It Have?
- Outer Core
- Its Between 4,000-5,000
What’s The 3rd Layer Of Earth and What Characteris Does It Have?
- Mantle
- 500-900 Degrees Thick
- Convection Currents Happen Here
What’s The 4th Layer Of Earth and What Characteris Does It Have?
- Crust
- Its Between 0-60KM Thick
What Are The 2 Types Of Crust Called?
Oceanic and Continental
What The Difference Between Continental and Oceanic Crust?
- Continental Has Land On It And Its Light and Can’t Sink.
- Oceanic Doesn’t Have Land and Its Heaver and Can Sink
How Many Large And Small Plates Are Their?
- Large Plates - 7
- Small Plates - 12
What Causes These Plates To Move and Where Is It Located?
Convection Currents Which Are Located In The Mantle
What’s The Key Word Called When 2 Plate Meet Together?
- Plate Margin Or Plate Boundaries
What’s The 3 Plate Boundaries Called
- Destructive
- Constructive
- Conservative
What Natural Disaster Happens At Destructive Plate Boundaries?
- Volcanoes and Earthquakes
What Natural Disaster Happens At Constructive Plate Boundaries?
- Volcanoes and Earthquakes
What Natural Disaster Happens At Conservative Plate Boundaries?
- Only Volcanoes
In 3 Steps What happens at a Constructive plate boundary?
- 1) At Constructive plate boundaries 2 plates are pulling apart.
- 2) Magma Rises up through the gap in the earths crust.
- 3) Forming Shield Volcanoes and creating islands like Iceland.
In 4 Steps What happens at a Destructive plate boundary?
- 1) At Destructive plate boundaries the 2 plates are going towards each other.
- 2) Oceanic Plates are thinner and made of dense material than Continental plates.
- 3) When they meet the Oceanic Plate sinks underneath the less dense Continental plates into the subduction zone.
- 4) The incredible force of this struggle causes powerful effects on the earth forming composite volcanoes.
In 2 Steps What happens at a Conservative plate boundary?
- 1) The plates aren’t moving towards each other or away from each other. But actually moving alongside each other at different speeds or in opposite directions.
- 2) when the plates get stuck and then finally dislodge a earthquake forms at the earths surface due to the amount of energy and pressure released.
Write a Definition Of a Ocean Trench?
- Its The Land Between The Oceanic and Continental Plate
List 4 reasons why people live near earthquakes or volcanoes And explain them
- Geothermal Energy - Creates Renewable Energy Sources.
- Farming - Volcanic Ash Makes The Soil Very Fertile.
- Mining - Sulfur Is Found Near Their.
- Jobs - Lots Of Tourism Jobs And Lots Of Hotels,Restaurants and Souvenir Shops Which Help Income.
Name 3 Things That Could Predict That There Is A Volcano and explain Them?
- Gases
- Changes In Heat
- Vibrations Underground
Explain How Scientise Will Know a Volcanoes Will Happen Due To The Gases Released?
- Certain Gases Indicate Rising Magma Such as Sulphurous Gases and radon gas.
What Scale Is Used To Measure Earth Quakes?
- Righter Scale
What’s The acronym To Reduce a Earthquake?
- S -Strong Influstucutere
- E - Early Warning
- C - Community Awareness
What’s The Acronym To Reduce a Volcano?
- M -Monitoring
- E -Engineering Solutions
- C - Community Preparedness
What Caused The L’Aquila Earthquake?
L’Aquila Is Situated Along The North West - South East Paganica Fault Line And The Fault Lines Occurs At The Boundary Of Tectonic Plates.
What Caused The Gorkha Earthquake?
- The Earthquake Occured on a Convergent Plate Boundary Between The Indian and Eurasian Plate Both Plates Collided.
