Unit 2 Geography Flashcards
sunday revision
This is the day to day climatic conditions and changes in the atmosphere.
Weather
This is the average weather, generally over 30 years.
Climate
Is the layers of gases that surround the Earth.
Atmosphere
This is a device for measuring wind speed.
Anemometer
This is a device used to measure the atmospheric pressure of a place.
Barometer
This is an instrument used to measure temperature.
Thermometer
This is a unit used to express the extent of cloud clover. It is equal to
one-eighth of the area of the sky.
Oktas
This is a data presentation technique that shows the temperature and the
rainfall of a country over one year using lines and bars.
Climate graph
This is when warm and cold fronts meet, creating rainfall
Frontal rainfall
This is rain that occurs on high land and in mountainous areas.
Relief rainfall
This occurs in warm or tropical climates when heated air rises and cools
Convectional rainfall
This is a large body of air with similar characteristics of temperature and
humidity.
Air mass
This is a vast body of air that forms over water
Maritime (air mass)
This is a vast body of air that forms over the interior of a continent, excluding
maritime areas.
Continental (air mass)
This is when a climate in a small area is different to the general surroundings.
Microclimate
This is the compass direction that a place faces
Aspect
This is a structure or building that provides protection from the local environment.
Shelter
This is a prediction made with limited evidence at the beginning of a scientific
investigation.
Hypothesis
This describes and justifies the way that data was collected.
Methodology
This is used to measure the strength of the wind.
Beaufort Scale
The stage of your investigation where you reflect on how your investigation
has gone. What went well in your investigation? What didn’t go well in your
investigation? What would you do to improve it for next time?
Evaluation
The good or beneficial quality of a person or thing
Strength
This describes a restriction or something that is not as good as it could be.
Limitations
This describes the action of making something better
Improvement
This is the stage in your investigation where you sum up the findings of your
investigation, referring back to your original enquiry question.
Conclusion
This is a slow-moving ice mass, formed over a long period from compacted
snow
Glacier
This is a steep-sided U-shaped valley formed by the erosive forces of a
glacier.
Glaciated valley
This is a long period of reduction in the temperature of the Earth’s surface and
atmosphere, resulting in the presence or expansion of ice sheets and alpine
glaciers
Ice age
This is a large, permanent area of ice which could expand in most directions.
Ice sheet
This is moisture falling from the atmosphere eg. rain, snow or sleet.
Precipitation
This is the process of a substance changing from a solid to a gas
Sublimation
This is when water in rocks freezes and expands, breaking the rock apart.
Freeze-thaw weathering
This is a type of glacial erosion that occurs when ice freezes into the
landscape, ripping out rocks when it moves
Plucking
These are grooves or scratches on bedrock caused by the movement of a
glacier
Striations
This is the sandpaper effect of glacial ice scouring a valley floor and sides.
Abrasion
This occurs when material being transported by ice is dropped due to the ice
melting.
Deposition
This is a bowl-shaped hollow area formed by glaciation, sometimes containing
lakes or ‘tarns’.
Corrie
This is when ice in a corrie melts, a circular lake is often formed at the bottom
of the hollow.
Tarn
This is a sharp ridge of rock separating two corries
Arête
This is a sharply pointed mountain peak that has been formed by glaciation.
Pyramidal peak
This is a narrow valley with steep sided slopes
V-shaped valley
This is a wide valley carved out by glaciers.
U-shaped valley
This is a long narrow lake found in a glacial trough.
Ribbon lake
This is a smaller valley which is located high above the main U-shaped valley
Hanging valley
This is the debris, rocks and materials that a glacier has picked up,
transported and then deposited.
Moraine
This is a mound of deposited moraine
Drumlin
This is a large rock fragment transported by ice away from its place of origin
Erratics
This is a person that is travelling or visiting a place for pleasure
Tourist
This is a natural fuel such as coal or gas.
Fossil fuel
This is an international agreement signed on 23 June 1961 to ensure
economic development did not happen at the expense of the environment.
Arctic treaty
