page 20
Altitude (n.): height above sea-level
Basin (n.): a natural depression on the Earth's surface, typically containing water
Bay (n.): a curved indent to the coastline, usually created by a high rate of erosion
Depression (n.): sunken or depressed areas below the surrounding areas
Erosion (n.): the gradual destruction removal of rock material by an agent (water, wind or ice)
Estuary (n.): area where the sea flows into the mouth of a river
Glacier (n.): a mass of ice formed through the accumulation and compaction of snow
Gulf (n.): a deep inlet of the sea (similar to a bay) almost surrounded by land, with a narrow mouth

Plain (n.): a large area of flat land, no higher than 200 m above sea level
Plateau (n.): an area of flat land higher than 200 m above sea level
UNIT 5. Atmosphere, weather, climate and living things
page 47
Gases (n.): air-like fluid substance which expand freely to fill any space available
Humidity (n.): the amount of water vapour in the atmosphere or a gas
Meteorology (n.): the science dealing with the atmosphere and its phenomena, including weather and climate

Anticyclones: a circulation of winds around a central region of high atmospheric pressure
Barometer: an instrument that measures atmospheric pressure
Condense: to reduce to a denser form (e.g. a gas or vapour to a liquid or solid state)
Depressions: an area of low atmospheric pressure
Isohyets: the lines drawn on a map, connecting points that have equal amounts of precipitation
Pluviometer: an instrument that measures atmospheric pression
Precipitation: falling products of condensation in the athmosphere (e.g. rain, snow or hail)
