Earth science/geography

a careful preservation
and protection of something

caring for these resources
so all living things can benefit
from them now and in the future

protecting our environment
and the wildlife that lives in it

aquatic enviroments

high levles of dissolved salt

limits reproduction

damage aquatic food chain

extincintion of species

soil, trees, insects,
animals, birds

a geographic area where plants,
animals, as well as weather and
landscape, work together

large open areas
of grass

area in which the vegetation
is dominated by a nearly
continuous cover of grasses

areas of land characterised
by extremely high or low
temperatures

has a layer of soil that
can be sandy, or stony

cold and dry

receives low amounts
of precipitation

removes carbon from the
atmosphere and puts it back
in the soil

a way of farming that
seeks to actively improve
the health of the environment

contains stored chemical energy
from the sun that is produced by plants
through photosynthesis

can be burned directly for heat or
converted to liquid and gaseous
fuels through various processes

energy in the core of a atom

a form of energy released from
the nucleus, the core of atoms,
made up of protons and neutrons.

The light and heat
that comes from the sun

non-renewable
energy source

fuel to generate
electric power

power produced
with moving water

one of the oldest power
sources on the planet

heat energy from
the earth

a renewable energy source
because heat is continuously
produced inside the earth

process by which the wind is
used to generate mechanical
power or electricity

Generating electricity
(wind turbines)

lower emissions

low cost

can happen because of
natural or human factors

the process by which
vegetation in drylands
such as grasslands decreases
and eventually disappears

dersetfication can be
reduced
by planting more trees

plains

erosional plains

air, ice, or water wears away at
land and little bits of the land are washed away.

Valleys

A long ditch in earths surface

plateaus

a flat, elevated landform that
rises sharply above the
surrounding area on at least one side.

mountain

Mountains are formed by
slow but gigantic movements
of the earth's crust

desserts

a region of land that is very dry

itrevieves low amounts
of perticapation

Landfiils

energy that is transferred
from one body to another
as the result of a difference
in temperature

the transfer of thermal
energy between substances

conduction, convection,
and radiation
