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
