Polar cell
At around 60°, warm air rises, leading to clouds and rain. The air will then flow back to the poles.
Cold air descends at the poles, creating high-pressure areas that lead to clear skies.
Warm air flows towards the equator, causing tropical storms and heavy rainfall.
Air circulates in a circular pattern around the equator, leading to consistent weather patterns.
Immediate responses to weather hazards
Emergency aid and assistance
Long-term recovery planning
Infrastructure development
Public awareness campaigns
Long-term responses to tectonic hazards
Focus on immediate evacuation and rescue operations.
Focus on rebuilding and restoring normal life, repairing buildings and transport links, and reducing future damage.
Focus on providing temporary shelters and food supplies.
Focus on assessing the damage and conducting research on tectonic activity.
Hadley cell
Air rises at the equator, creating low pressure and rainfall.
Air descends at the poles, creating high pressure and dry conditions.
Air rises at 30°, creating low pressure and rainfall.
Air cools and falls at the equator, creating high pressure and dry conditions.
Impact of climate change on tropical storms
More frequent and intense storms, sea level rise, and more destructive flooding due to warmer air holding more moisture.
Decrease in storm frequency and intensity due to cooler ocean temperatures.
No significant impact on tropical storms as climate change is a myth.
Increased storm frequency but less intensity due to climate stabilization.
Types of crust: Oceanic
5-10km thick
10-15km thick
15-20km thick
20-25km thick
Pressure belts
Descending air leads to low pressure and rain.
Rising air results in high pressure and no clouds.
Descending air results in high pressure and no clouds and rain.
Rising air leads to low pressure and clear skies.
Gorkha, Nepal 2015 (LIC) - Immediate Responses
Rescue efforts were enhanced by the availability of tools
130,000 families housed in emergency shelters
All injured were treated immediately
Charities provided aid without any delays
Plate tectonic theory: Slab pull
At subduction zones, older denser plates sink into the mantle – pulling newer/less dense bits of plate with it.
At divergent boundaries, plates move apart, creating new crust.
At transform boundaries, plates slide past each other without creating or destroying crust.
At all plate boundaries, plates are constantly moving in the same direction.
Layers of the earth
Crust: Thinnest outermost layer.
Mantle: Thickest layer (approx. 2,900km).
Core: Inner core is solid; outer core is liquid.
Atmosphere: The layer of gases surrounding the Earth.
Secondary Effects of Typhoon Haiyan
Flooding triggered landslides
5.6 million jobs created
Outbreaks of disease, e.g., cholera
5.6 million jobs lost
Impacts of the Extreme Weather Event (Somerset Levels rainfall and flooding)
600 homes flooded
£80 million damage
11,500 hectares flooded

Prediction of tropical storms
Using super-computers to predict where the storm will hit using a track cone.
Relying solely on satellite imagery to track storms.
Using historical data without any computer assistance.
Waiting for local news reports to provide updates.
Prediction of tectonic hazards
Using historical evidence and live data to estimate when hazards might occur, especially after recent activity.
Relying solely on geological surveys to predict future tectonic events.
Analyzing satellite images to determine tectonic plate movements.
Conducting interviews with local residents about past earthquakes.
Monitoring tectonic hazards
Using scientific equipment to detect warning signs like temperature changes and bulges in the volcano dome.
Relying on historical data to predict future eruptions.
Observing animal behavior for signs of volcanic activity.
Conducting surveys of local populations for anecdotal evidence.
Protection from tropical storms
Building homes on stilts to protect from flooding
Using solar panels to generate electricity
Installing air conditioning units
Painting houses bright colors to reflect sunlight
Primary impacts of tectonic hazards
Loss of life, buildings destroyed, and infrastructure damaged
Increased agricultural productivity and crop yields
Enhanced tourism and economic growth
Improved air quality and environmental conditions
Types of plate margin: Constructive
When plates move apart, magma rises to the surface and cools to form new land, e.g., a mid-ocean ridge, which can cause volcanoes and earthquakes.
When plates collide, one plate is forced under another, leading to mountain formation and earthquakes.
When plates slide past each other, causing friction and earthquakes, but no new land is formed.
When plates are stationary, leading to the formation of sedimentary basins and no volcanic activity.
Secondary impacts of tectonic hazards
Outbreaks of diseases, increased tourism, and tsunamis
Increased agricultural production and improved infrastructure
Reduction in natural disasters and economic growth
Enhanced biodiversity and climate stability
