- 1AtmosphereEnvelope of particles and gasses that surrounds the Earth
- 2Origin of AtmosphereIt is biological; the oxygen was released by photosynthetic bacteria
- 3Composition of atmosphereAir: 78% Nitrogen
21% Oxygen
1% Other gases - 4Layers of AtmosphereTroposphere
Stratosphere
Mesosphere
Termosphere
Exosphere - 5Functions of AtmosphereProtection against solar radiation
Regulation of temperatures
Source of nutrients:
Oxigen for repiration
Co2 for photosintesis - 6HydrosphereEnvelope of water any where and in any state of Earth
- 7Origin of HydrosphereTerrestrial: water vapour released by volcanoes.
Extraterrestrial: Ice in meteorites (comets and ateroids) - 8Composition of Hydrosphere97% Saline water(seas and oceans)
3% Fresh water(Ice, ground water...) - 9Properties of water1. Great solvent.
2. Hard to heat and cool.
3. Ice less dense than water.
4. chages It's state. - 10Roles of water in living things1. Medium for chemical reactions.
2. Transport of substances.
3. Thermoregulator.
4. Aquatic enviroments. - 11Water use in human activitiesDomestic uses: for drinking,
Agricultural uses: to irrigate crops
Industrial uses: cleaning machinery, - 12Water cycle processesCondensation: Water vapor transforms into small liquid droplets in clouds.
Precipitation: Tiny cloud droplets fall out from sky (rain, hail, sleet or snow)
Flow: Water circulation on surface or underground.
Infiltration: Water infiltrates on soil pores.
Evaporation: Liquid water becomes water vapor on air.
Transpiration: Living things release water vapor to the atmosphere. - 13Roles of water organismsMedium for chemical reactions.
Transport of substances.
Regulation of temperatures.
Medium for living organisms. - 14TroposphereIt is the thinnest and densest layer close to the geosphere. It
contains about 80% of the atmosphere’s mass. Here, meteorological
phenomena occur. - 15StratosphereIt contains the ozone layer, which absorbs ultraviolet radiation.
- 16MesosphereHere meteorites burn up, which protect us from their impact.
- 17Exospherecomets and satellites appear in this layer.
- 18Greenhouse effectphenomenon which maintains a constant temperature on Earth due to some atmospheric gases. These gases absorb part of the energy released by the surface as a result of the warming by solar energy.
- 19LakeA large body of water surrounded by land.
- 20RiverA body of flowing water moveing towards the sea.
- 21Weather stationFacility for measuring and recording different meteorological variables.
- 22Instruments for mearureing meteorological variablesThermometer
Barometer
Hygrometer
Anemometer
Wind vane
Rain gauge - 23Saveing waterReduce water use
Recycle water
Prevent contamination - 24Water cycleThe movement of water on the Earth ́s surface and through the atmosphere is caused mainly by solar energy and gravity.
- 25CondensationWater vapor transforms into small liquid droplets in clouds.
- 26PrecipitationTiny cloud droplets fall out from sky (rain, hail, sleet or snow)
- 27FlowWater circulation on surface or underground.
- 28InfiltrationWater infiltrates on soil pores.
- 29EvaporationLiquid water becomes water vapor on air.
- 30TranspirationLiving things release water vapor to the atmosphere.
