Weather Hazard

Question 1

What is a Weather Hazard?

Answer 1

A weather hazard is an extreme weather event that threatens people or property.

Question 2

Hadley Cell

Answer 2

Warm air rises at the equator, causing rainforests. 🌴

Question 3

Ferrel Cell

Answer 3

Cooler air sinks, causing deserts. 🏜️

Question 4

Polar Cell

Answer 4

Cold air sinks at the poles. ❄️

Question 5

What are Tropical Storms?

Answer 5

🌊 Massive storms with strong winds and heavy rain.

📍 Form over warm oceans (27°C+), near the Equator.

🌪️ Rotate because of the Coriolis Effect.

💨 Get stronger over warm water, but weaken over land.

Question 6

Impacts of Tropical Storms

Answer 6

✔ Primary Effects (Immediate) – Flooding, roofs blown off, trees fall.

✔ Secondary Effects (Later Impacts) – Disease from dirty water, no electricity, businesses shut down.

Question 7

How to Reduce the Impact of Tropical Storms?

Answer 7

✔ Monitoring & Prediction – Satellites track storms.

✔ Protection – Houses on stilts, sea walls.

✔ Planning – Evacuation routes, emergency supplies ready.

Question 8

Types of UK Extreme Weather

Answer 8

❄️ Heavy snow & ice – Transport stops, crops die.

🌧️ Flooding – Caused by heavy rain, storms, or melting snow.

💨 Strong winds – Trees fall, power cuts.

🔥 Heatwaves – Water shortages, drought.

Question 9

Managing Climate Change

Answer 9

🌳 Mitigation (Stopping It) – Renewable energy, planting trees.

🏡 Adaptation (Living With It) – Flood defences, drought-resistant crops.

Question 10

How Does Air Sink? 🌬️⬇️

Answer 10

Air sinks when it cools down and becomes heavier (denser).

🔹 Warm air rises because it is lighter and has more energy.

🔹 As it rises, it cools and loses energy.

🔹 Cooler air becomes denser and starts to sink.

This happens in high-pressure areas, like:
✔ 30° North & South of the Equator → Creates deserts (dry air sinks). 🏜️
✔ Poles (North & South) → Cold air sinks at the poles, forming high-pressure areas. ❄️
