GEO_Vocab_GP4_Atmosphere and Climate Flashcards
Convection
Transfer of thermal energy by the circulation of a fluid (air or liquid)
Greenhouse Effect
This occurs when the gases in the Earth’s atmosphere trap thermal energy and keep the planet warm.
climate
average weather conditions in an area over a long period of time. Primarily determined by temperature and precipitation
Mediterranean climates (Chaparral)
cool wet winters and hot dry summers. Plants are mainly drought resistant evergreen shrubs.
a stratus cloud that is formed when water vapor condenses near the ground
fog
front
the boundary formed when two air masses with different characteristics collide
biome
a large region characterized by a specific type of climate and the plants and animals that live there
wind created by
differences in air pressure; the greater the air pressure difference the stronger the wind.
cool wet winters and hot dry summers. Plants are mainly drought resistant evergreen shrubs.
Mediterranean climates (Chaparral)
The layer closest to the earth’s surface from 0-16km in altitude. It contains about 90% of the atmosphere’s air. CO2, water vapor, clouds, air pollution and weather all reside in this layer.
Troposphere
The layer that is 16-50 km in altitude and is very thin except for the upper portion which contains a large amount of ozone.
Stratosphere
Transfer of energy from one thing to another by direct contact.
Conduction
weather which causes property damage or harm to people.
severe weather
monsoon
a wind reversal which causes changes in air pressure and precipitation in a particular area.
Radiation
Transfer of energy as electromagnetic waves.
fog
a stratus cloud that is formed when water vapor condenses near the ground
strato
prefix for clouds that form at low altitudes
snow
the most common form of solid precipitation; it is made up of ice crystals when water freezes very quickly.
Tropical rain forests
Forests which are wet year-round
occurs when cold air displaces warm air, pushing it up and often creating thunderstorms , rain or snow, followed by cold weather
cold front
global winds
move across the entire Earth in specific directions.
prefix for clouds that form at high altitudes
cirro
Convection current
A circular movement of air caused by the continual process of rising and falling air.
Transfer of thermal energy by the circulation of a fluid (air or liquid)
Convection
Desert
Dry climates which receive less than 25cm of rain per year.
air mass
a large body of air with a similar temperature and humidity throughout; characteristics depend on where they form
sound waves caused when lightning strikes releasing energy which causes air to expand rapidly moving faster that the speed of sound
thunder
A circular movement of air caused by the continual process of rising and falling air.
Convection current
This occurs when the gases in the Earth’s atmosphere trap thermal energy and keep the planet warm.
Greenhouse Effect
alto
prefix for clouds that form at middle altitudes
occurs when cold and warm air meet and stay fairly still. Weather can be similar to that of a warm front
stationary front
Forests which are wet year-round
Tropical rain forests
Carbon dioxide, water vapor, methane
greenhouse gases
taiga (Boreal Forest)
are found just south of the tundra. This area experiences long cold winters an short warm summers. Conifer forests and little else grow here.
Atmosphere
A mixture of gases that surrounds the Earth
Wetlands
Seasonally or permanently saturated with water - some of these are freshwater, some are saltwater
hail
lumps of ice which form in layers high up in the air; the ice will fall towards the ground until an updraft brings it higher where it will freeze, then fall again and repeat the process many times
Deserts which tend tostay above freezing while experiencing a large daily temperature range
Tropical Deserts
differences in air pressure; the greater the air pressure difference the stronger the wind.
wind created by
cirro
prefix for clouds that form at high altitudes
a large rotating tropical weather system with wind speeds of at least 119 km/hr.
tropical cyclone
The layer from 50-80km and is a cold, thin layer with heavy winds.
Mesosphere
Warm summers and cold winters - with too little rain for tress
Temperate Grasslands
occluded front
occurs when a cold fron overtakes a wanr front forcing the warm air up. This type of front bring cold temperatures and a lot of precipitation.
large electrical discharge between two oppositely charged surfaces
lightning
Thermosphere
Highest layer from 80-600 km, and is a thin layer with a high temperature.
Warm temperature year round with a short rainy season
Tropical Grasslands
experience four seasons with warm summers, and cold winters, and high precipitation. Some are deciduous while others are coniferous.
temperate forests
