Precious Resources Flashcards
Wind energy
Wind energy: a renewable energy derived from the wind (caused by uneven heating of the Earth and its oceans by the sun), for example by the use of wind turbines in a wind farm
Biomass
Biomass: material produced by living organisms
Ocean wave energy
Ocean wave energy: a renewable energy created by converting the mechanical energy of ocean waves to electrical energy
Tidal energy
Tidal energy: a renewable energy that can be harvested from the tides in the ocean through the use of large underwater turbines placed in areas of high tidal movement
Geothermal energy
Geothermal energy: heat energy transferred from rocks below the Earth’s surface
Hydro-electric
Hydro-electric: power produced by the energy of falling water
Nuclear energy
Nuclear energy: the energy stored at the centre of atoms, the tiny particles that make up all substances. Nuclear energy can be released from the radioactive metals uranium or plutonium and transformed into electrical energy in a nuclear power station
Turbines
Turbines: wheels that, when turned, drive electrical generators. Steam or water are often used to turn turbines.
Evaporation
When a liquid turns into a gas
Ice
Water as a solid
Snow
Water as a solid
Transpiration
When water is released as a gas
Condensation
When water as a gas turns into water as a liquid
Precipitation
The fancy word for rain
Percolation
When water moves from above the ground to underground
