Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit teaches pupils about the physical processes that help explain our weather and climate. Pupils will use fieldwork to investigate weather in their local area. Pupils will also learn about how and why our climate is changing.
Lesson Summary
You will learn to explain the weather associated with a depression.
Key Notes
- Depressions are areas of low pressure where air is rising.
- Warm air and cold air meet at depressions causing changeable temperatures and rain.
- Depressions bring windy conditions shown by closely spaced isobars.
- Typically the passage of a depression over the UK can last between 1 and 5 days.
Vocabulary To Learn
- pressure: a force pushing or pressing on a given area
- air mass: a mass of air with the same levels of temperature, humidity, and pressure
- depression: an area of low pressure characterised by rain, wind and cloud
- front: a weather front is the boundary between a warm air mass and a cold air mass
Common Mistakes To Avoid
- The weather associated with an anticyclone stays the same all year around.
