EARTH & LIFE SCIENCE EARTH & EARTH SUBSYSTEM Flashcards
(46 cards)
what zone is earth that supports life
Goldilocks zone
habitable zone
Goldilocks zone
a terrestrial planet located in the goldilocks zone (habitable zone)
EARTH
3rd planet from the sun
EARTH
the range of distance with the right temperatures for water to remain liquid
Goldilocks zone
5th largest planet in the solar system
EARTH
only habitable planet or planet known in the solar system that can support life
EARTH
has a unique physical and chemical characteristics compare to other neighboring planets
EARTH
factors that makes earth habitable
- Temperature
- Water
- Atmosphere
- Energy
- Nutrients
NOT ENOUGH OF THIS FACTOR will
cause chemicals to react slowly, which interferes with the reactions necessary for life
Temperature
influences how quickly atoms and molecules move
Temperature
NOT ENOUGH OF THIS FACTOR will freeze water, making liquid water unavailable
Temperature
liquid water can still exist under certain conditions
Temperature
life seems limited to a temperature range of
-15 degree C to 115 degree C
TOO MUCH OF THIS FACTOR will at about 125 degree C, protein and carbohydrate molecules and genetic material
Temperature
Dissolves and transports chemicals within and to and from a cell
Water
is regularly available
Water
life can go dormant between wet periods but eventually THIS needs to be available
Water
NOT ENOUGH OF THIS FACTOR will make the chemicals that a cell needs for energy & growth are not dissolved or transported to the cell
Water
TOO MUCH OF THIS FACTOR is not a problem, as long as it is not so toxic that it interferes with the chemistry of life
Water
it keeps the surface warm & protects it form radiation & small-to medium-sized meteorites
Atmosphere
How thick is the earth’s Atmosphere
100 miles thick
Traps heat, shields the surface from harmful radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide
Atmosphere
organisms use light or chemical _________ to run their life process
Energy
