Unit 1 Flashcards
environment
all living and non-living things around us (abiotic & biotic factors)
environmental science
study of how natural world affects us, and we affect it
natural resources
substances and energy sources we take from Earth to survive
renewable
replaced quickly, such as wind or sunlight
non-renewable
replaced slowly, so it can be depleted (e.g. fossil fuels)
ecosystem services
agricultural revolution
industrial revolution
ecological footprint
overshoot
science
variables
independent variables
dependent variables
hypothesis format
prediction format
data
data analysis
descriptive statistical tests
manipulative experiment
natural experiment
paradigm
paradigm shift
organism
individual living thing
population
a group of individuals of species that live in a particular area
community
a set of populations of different species living together in a particular area
ecosystem
a functional system consisting of a community
landscape
a geographical region including an array of ecosystems
biosphere
the sum total of living things on the Earth & the areas they inhibit
biome
major regional complex of similar communities. mainly determined by temperature & precipatation
number of biomes
10 terrestrial biomes exist
Terrestrial Biomes
Diff in temp & Percipitation predict type
Tropical
23.5 north and 23.5 south latitudes
Temperate
Between 23.5 and 60 north and south latitudes (THINK MODERATE)
Arctic & SubArctic
Above 60 north latitude
Where are there no Biomes and why?
Antartica has no biomes, too cold for rain —> no plants
Terrestrial Biomes and elevation
Elevation also affects climate
Each 1000’ increase lowers temp by 4 degrees
Mountains can enable cool-loving biomes to exist at hotter latitudes
Rain Shadow
Dry climate created downwind of a mountain b/c most moisture condenses on it upwind side (no precipatation on downwind side of mountain)
Climate diagram
graph depicting seasonal changes in temp and precipitation
Temperate Deciduous Forest
Less dense & diverse than rainforest - not as much rain means they have less diversity
deciduous
loses leaves
temperate grassland
looks like praire
less precipitation, considerably colder
we artificially water these and turn them into agriculture land
temperate rainforest
considerably more rain
lot of mass & density
bit hotter temps in summer
Tropical rainforest
insane amt of rain, only slight differences across
not as fertiles bc the rain washes nutrients
not much temp variation
Pelagic zone
Layer b/w water surface and lake & ocean floor
includes photic zone
Tropical Dry Forest
temp is consistent but precipitation changes seasonally
very bare with distinct wet/dry seasons & w/ or w/o leaves
Australia
