Q

TYPES OF RAINFALL:

What is the formation of ‘frontal rainfall’? (2)

A

1.) • When a mass of warmer air meets a mass of colder air
➡ it RISES UP, over the colder HEAVIER air 💨↗️

2.) • Once it is made to rise
➡ it will COOL and condense
↳ forming rainfall 🌧️

18
Q

What is the formation of relief rainfall? (3)

A

1.) • When MOIST air meets a mountain
➡ it is forced to RISE 💨↗️

2.) • A it does so,
➡ it cools and condenses
↳ forming clouds and rainfall 🌧️

3.) • This causes upland areas to be WETTER 🌧️

19
Q

What is the formation of convectional rainfall? (2)

A

1.) • When the GROUND is heated by the sun
➡ the air is WARMED ☀️

2.) • This air rises up, and as it does
➡ it cools and CONDENSES
↳ forming cloud and rainfall 🌧️

Q

FACTORS AFFECTING LOCAL WEATHER/TEMPERATURE VARIATIONS:

What are the points and explanations to explain UK temperature variations? (8)

A

1.) • 🟢 Northern areas
➡ are closer to the North Pole
• 🟠 where the sun’s rays are less concentrated
➡ making it colder ❄️

2.) • 🟢 Areas
➡ with snow and ice
• 🟠 reflect the heat of the sun
➡ making it colder ❄️

3.) • 🟢 Inland areas
• 🟠 are further away from cool coastal winds 🌬️
➡ making it hotter ☀️

4.) • 🟢 Mountains
• 🟠 cause temperatures to decrease as altitude increase
↳ (by 1°C for every 100m)
➡ making it colder ❄️

5.) • 🟢 Coastal areas
• 🟠 are closer to the sea which cools more slowly during winter
➡ making it hotter ☀️

6.) • 🟢North facing areas
• 🟠 receive less sun light
➡ making it colder ❄️

7.) • 🟢 Western coastal areas
• 🟠 are close to a warm ocean current (North Atlantic Drift)
➡ making it hotter ☀️

8.) • 🟢Large urban areas
• 🟠 have many buildings that can trap in heat
➡ making it hotter ☀️
