Earth science/geography
climate change
Heat
conduction, convection,
and radiation
the transfer of thermal
energy between substances
energy that is transferred
from one body to another
as the result of a difference
in temperature
landdfills
Landfiils
forest fires
air pullution
illnesses
death
parents cry
green house gases
burning fossil fuels
releases nitrogen oxides
everyone is exposed to small bits of nitrogen oxiges
damage the respirtory airways
glaciers melting
polar bears dying
Landforms
desserts
a region of land that is very dry
itrevieves low amounts
of perticapation
mountain
Mountains are formed by
slow but gigantic movements
of the earth's crust
plateaus
a flat, elevated landform that
rises sharply above the
surrounding area on at least one side.
Valleys
A long ditch in earths surface
plains
erosional plains
air, ice, or water wears away at
land and little bits of the land are washed away.
desertification
dersetfication can be
reduced
by planting more trees
the process by which
vegetation in drylands
such as grasslands decreases
and eventually disappears
can happen because of
natural or human factors
Energy sources
Natural Gas
low cost
lower emissions
Wind
Generating electricity
(wind turbines)
process by which the wind is
used to generate mechanical
power or electricity
Geothermal
a renewable energy source
because heat is continuously
produced inside the earth
heat energy from
the earth
Hydropower
one of the oldest power
sources on the planet
power produced
with moving water
Coal
fuel to generate
electric power
non-renewable
energy source
Solar
The light and heat
that comes from the sun
Nuclear
a form of energy released from
the nucleus, the core of atoms,
made up of protons and neutrons.
energy in the core of a atom
Biomass
can be burned directly for heat or
converted to liquid and gaseous
fuels through various processes
contains stored chemical energy
from the sun that is produced by plants
through photosynthesis
regenerative agriculture
a way of farming that
seeks to actively improve
the health of the environment
removes carbon from the
atmosphere and puts it back
in the soil
ecosystems
tundra ecosystem
receives low amounts
of precipitation
cold and dry
dessert ecosystem
has a layer of soil that
can be sandy, or stony
areas of land characterised
by extremely high or low
temperatures
grassland ecosystem
area in which the vegetation
is dominated by a nearly
continuous cover of grasses
large open areas
of grass
forest ecosystem
a geographic area where plants,
animals, as well as weather and
landscape, work together
soil, trees, insects,
animals, birds
Marine/aquatic ecosystem
aquatic enviroments
high levles of dissolved salt
damage aquatic food chain
extincintion of species
limits reproduction
Humans
deforestation
10% of global warming
Conservation
protecting our environment
and the wildlife that lives in it
caring for these resources
so all living things can benefit
from them now and in the future
a careful preservation
and protection of something
