  • What is the outermost layer of the Earth called?
    The crust
  • What causes tectonic plates to move?
    Convection currents in the mantle
  • What is slab pull?
    A force causing tectonic plate movement
  • Where are tectonic hazards mainly found?
    At plate boundaries
  • How do continental and oceanic plates differ in density?
    Continental plates are less dense than oceanic plates
  • What are the types of tectonic plate boundaries?
    • Collision
    • Constructive
    • Destructive
    • Conservative
  • What causes earthquakes?
    Release of stored energy in plates
  • What is the focus of an earthquake?
    The underground point where energy is released
  • What is the epicenter of an earthquake?
    The point on the surface directly above the focus
  • How does the depth of the focus affect earthquake severity?
    Deeper focuses tend to be less severe
  • What type of volcano is characterized by high viscosity lava?
    Composite volcanoes
  • What are the primary effects of an earthquake?
    Ground shaking and infrastructure damage
  • How are earthquakes measured?
    Using the Richter scale
  • What magnitude on the Richter scale is considered severe?
    Anything over 6
  • Why was the damage from the Haiti earthquake worse than expected?
    Poor building standards and dense populations
  • What hindered aid efforts in Haiti after the earthquake?
    Significant damage to infrastructure
  • What was the magnitude of the Haiti earthquake in January 2010?
    7.0
  • What was a major criticism of international aid in Haiti?
    Slow response and poor local collaboration
  • How did the earthquake impact Haiti's economy?
    Caused huge poverty and loss of trade
  • What technology can help predict potential earthquake danger?
    Satellite technology measuring plate movement
  • What are P waves?
    Fast traveling primary waves from earthquakes
  • How can alerts be communicated before secondary waves arrive?
    Using SMS, sirens, and radio
  • What building features can reduce earthquake damage?
    Triangular supports and shock absorbers
  • What are the processes involved in extreme weather patterns?
    • Rising hot air creates convection currents
    • Evaporation leads to condensation and precipitation
    • High pressure zones lead to dry conditions
    • Heavy precipitation can cause flooding
  • Where are tropical cyclones located?
    either side of the Equator
  • What effect does the Coriolis effect have on tropical cyclones?
    Causes them to spin in different directions
  • What happens to a tropical cyclone when it reaches land?
    It stops due to lack of evaporation
  • What triggers drought conditions during El Nino years?
    Weaker trade winds and reversed ocean currents
  • What was the rainfall reduction in Australia during the Big Dry?
    40-60% less rainfall
  • What measures did the Australian government take during the Big Dry?
    Offered subsidies for water conservation
  • What caused the flash floods in Boscastle in 2004?
    Heavy rain and deforestation
  • How many people were rescued during the Boscastle flood?
    150 people
  • What measures were taken after the Boscastle flood?
    Afforestation and improved flood defenses
  • What is the Quaternary period known for?
    Cyclical patterns of climate change
  • What is Milankovitch cycles theory?
    Earth's path changes affecting climate
  • What is a major effect of climate change on Tuvalu?
    Sea level rise causing flooding
  • How is the economy of Tuvalu affected by climate change?
    Saltwater intrusion makes land infertile
  • What are the expected effects of climate change in the UK?
    Increased flooding and species migration
  • What are the major processes of river and coastal landscapes?
    • Erosion: Breaking down rocks
    • Transportation: Moving eroded material
    • Deposition: Dropping off material
  • What are the types of weathering?
    Mechanical, chemical, and biological
