5 Questions
Match the following layers of the atmosphere with their descriptions:
Troposphere = The layer closest to the Earth's surface where weather occurs Stratosphere = The layer where the ozone layer is located Mesosphere = The layer where meteors burn up Thermosphere = The layer where the Northern and Southern Lights occur
Match the following gases with their percentages in the atmosphere:
Nitrogen = 78% Oxygen = 21% Carbon Dioxide = 1% Argon = 1%
Match the following parts of the biosphere with their descriptions:
Land = One of the three main components of the biosphere Water = One of the three main components of the biosphere Air = One of the three main components of the biosphere Organisms = The living components of the biosphere
Match the following organisms with their sizes:
Microbes and Bacteria = Small-sized organisms in the biosphere Huge Mammals = Large-sized organisms in the biosphere Plants = Medium-sized organisms in the biosphere Insects = Small-sized organisms in the biosphere
Match the following parts of the atmosphere with their functions:
Provides us with air = Function of the atmosphere Protects us from sun's rays = Function of the atmosphere Divides the atmosphere into layers = Function of the atmosphere Composed mainly of nitrogen and oxygen = Composition of the atmosphere
Study Notes
Layers of the Atmosphere
- Troposphere: lowest layer, extends up to 12 km, contains 75% of atmosphere's mass, weather occurs here
- Stratosphere: next layer, extends up to 50 km, contains ozone layer, protects from UV radiation
- Mesosphere: extends up to 80 km, meteors burn up here
- Thermosphere: extends up to 600 km, Aurora occurs here
- Exosphere: outermost layer, extends to 10,000 km, where atmospheric gases escape
Atmospheric Gases
- Nitrogen: 78.08%
- Oxygen: 20.95%
- Argon: 0.93%
- Carbon dioxide: 0.04%
Parts of the Biosphere
- Lithosphere: solid, rocky crust of the Earth
- Hydrosphere: all bodies of water, including oceans, lakes, and rivers
- Atmosphere: gaseous region surrounding the Earth
- Biosphere: region where life exists, includes all living organisms
Organisms by Size
- Microorganisms: bacteria, viruses, protists (typically microscopic)
- Macroorganisms: plants, animals, fungi (typically visible to the naked eye)
Functions of Atmospheric Parts
- Ozone layer: absorbs UV radiation, protecting life on Earth
- Greenhouse effect: traps heat, maintains Earth's temperature
