    • The core consists of two parts - an inner solid core and an outer liquid core.
    • The mantle is the thickest layer beneath the crust, composed mainly of molten rock.
    • Plate tectonics refers to the movement of large plates on the surface of the earth.
    • The lithosphere is the rigid upper part of Earth's interior that includes both the crust and the uppermost part of the mantle.
    • What is precipitation?
      Precipitation includes rain, snow, and other forms of water that fall from the atmosphere.
    • How does precipitation occur?
      Precipitation occurs when warm, wet air rises and cools, causing water vapor to condense.
    • Where does air rise to cause frequent precipitation?
      Air rises in low pressure belts.
    • Why are rainforests usually found in low pressure belts?
      Rainforests are found in low pressure belts because precipitation is frequent and often intense in these areas.
    • What is the precipitation level like in high pressure belts?
      Precipitation is extremely low in high pressure belts.
    • Where are deserts typically located?
      Deserts are normally near high pressure belts.
    • How can the location of high and low pressure belts affect weather patterns?
      The exact location of high and low pressure belts varies over time, affecting weather conditions in normally moderate areas.
    • What causes wind?
      Wind is caused by air moving from areas of high to low pressure.
    • Why are winds weak in high and low pressure belts?
      Winds are weak in high and low pressure belts due to the lack of pressure difference.
    • Where are winds strong?
      Winds are strong between pressure belts.
    • What happens when the pressure difference between high and low pressure areas is large?
      Winds can be extremely strong when the pressure difference is large.
    • Which region receives the most energy from the Sun?
      The equator receives the most energy from the Sun.
    • Which regions receive the least energy from the Sun?
      The poles receive the least energy from the Sun.
    • How does heat drive atmospheric circulation?
      Heat drives atmospheric circulation as warm air from the equator moves towards the poles.
    • What temperatures are typical in high pressure areas around 30° N/S?
      Temperatures can be very high around 30° N/S in high pressure areas.
    • Why are there few clouds in high pressure areas?
      There are few clouds due to the sinking air in high pressure areas.
    • What are the characteristics of polar climates?
      Polar climates have low temperatures all year round.
    • What are the different climate zones around the world?
      • Polar: Low temperatures all year round.
      • Temperate: Moderate summers and winters; frequent rainfall due to low pressure.
      • Tropical: Hot temperatures and high rainfall, usually near the equator.
      • Arid (Dry): Very low rainfall, hot or warm temperatures, usually near 30 N/S.
    • How does global atmospheric circulation affect weather?
      Global atmospheric circulation affects the world's weather and can lead to extreme weather conditions.
    • How does extreme weather vary between Australia and the UK?
      Extreme weather varies significantly; for example, Australia's summers are hotter and it has lower precipitation than the UK.
    • What is Australia's status in terms of precipitation?
      Australia has much lower precipitation than the UK and is the world's driest inhabited continent.
    • What is the rainfall in extremely dry years for Australia and the UK?
      Extremely dry years in Australia have less than 360 mm360 \text{ mm}, while in the UK, it is less than 950 mm950 \text{ mm}.
    • How do extreme winds in Australia compare to those in the UK?
      Australia has stronger extreme winds than the UK.
    • What causes strong winds in Australia?
      Strong winds in Australia are caused by tropical cyclones.
    • What is the strongest recorded wind in Australia?
      The strongest recorded wind in Australia is over 400 km/h400 \text{ km/h}.
    • What is the strongest recorded wind in the UK?
      The UK's strongest ever sea-level wind was over 220 km/h220 \text{ km/h}.
    • Describe how extreme weather varies in two contrasting countries.
      • Australia has hotter summers and milder winters compared to the UK.
      • Australia's average summer temperature is about 33°C33 \degree C, while London's is about 23°C23 \degree C.
      • Australia has much lower precipitation, averaging 465 mm465 \text{ mm} annually compared to the UK's 1150 mm1150 \text{ mm}.
      • Extreme winds in Australia can exceed 400 km/h400 \text{ km/h}, while the UK's strongest winds are around 220 km/h220 \text{ km/h}.
    • What causes strong winds in tropical storms?
      An area of very low pressure at the center of the storm
    • How does the pressure difference affect wind speeds in tropical storms?
      It creates strong winds due to the big pressure difference
    • What is the maximum wind speed that tropical storms can reach?
      More than 250 kilometres per hour
    • What can strong winds in tropical storms do to buildings and plants?
      They can damage or destroy them
    • What happens to loose objects during tropical storms?
      They can be picked up and transported by strong winds
    • What characterizes extreme rain in tropical storms?
      Extremely high amounts of precipitation falling rapidly
    • Why does extreme rain occur in tropical storms?
      Due to large amounts of warm, moist air being sucked towards the center
    • What happens to the warm, moist air as it moves towards the center of the storm?
      It rises, cools, and condenses, causing rain
    • What can be a consequence of the heavy rain in tropical storms?
      Flooding and mudslides can occur
