Universe creation and Natural cycles Flashcards
The First stage in universe creation?
No space or time
Only the “singularity”
Second stage in universe creation?
Time and space began
Expanded quickly
Third stage in universe creation
Expanded to size of a pea
Matter created in form of particles
Stage four of universe creation?
Protons and neutrons formed
No atoms
Stage five of universe creation?
Universe same size as our solar system
Stage six in universe creation
Nuclei of hydrogen, helium, lithium formed
Stage seven in universe creation
Universe expanded to one thousandth of size
First neutral atoms formed
Stage eight of universe creation
Galaxies began to form
Stars form
Nuclear reactions from elements collapse into stars
Swirling clouds of matter form lumps, form planets
Define Nitrification
Ammonia found in soil is turned into nitrates
Nitrogen cycle
Define Condensation
Water vapour in air is changed into liquid water
Causes cloud formation
Water cycle
Define Fossil fuels
Coal, oil, gas
Carbon cycle
Define Transpiration
Vapour released to atmosphere from plants
Water cycle
Define respiration
Animals breathe out carbon dioxide to oxygen
Carbon cycle
Define photosynthesis
Plants convert sunlight into glucose
Carbon cycle
Only in green things
Carbon dioxide + water - glucose + oxygen
Define evaporation
Liquid to gas
Water to vapour
Define transpiration
Evaporation of water from plant leaves
Define precipitation
Rain, snow, sleet falls or condenses on the ground
Define subsurface runoff
Water/precipitation running over ground and into bodies of water
What is a stomata
Structure releases water from leaf cell 2 guard cells Loss of water through stomata called transpiration Plant take Carbon through stomata
Cellular respiration
Plant and animal release energy from glucose
Release Carbon dioxide
Glucose + oxygen - Carbon dioxide + water
What happens in the nitrogen cycle
Nitrogen absorbed by plants Nitrogen into earth become nitrate Nitrate consumed by animals Animals death and decay Bacteria from animals Nitrogen back to atmosphere
What happens in Carbon cycle
Absorbed by plants and animals
Fossil fuels
Ground level
Back to atmosphere
What happens in water cycle
Evaporation
Condensation
Precipitation
