new nuclei and neutrons result from

the splitting of an atoms nucleus

in a nuclear power plant

three pipe circuits pump water through the reactor turbine and cooling tower

the first step in surface coal mining is

to remove and set aside the soil that covers the area to be mined

which of the following is an advantage of using fossil fuels for energy

versatility in their uses

which country uses the least amount of energy per person

Argentina

during the process of nuclear fission

a neutron splits a uranium 235 atom, forming new elements and releasing several neutrons plus energy

arid regions where rates of evaporation are high

which of the following is NOT a characteristic of a mineral

atoms in random geometric patterns

surface mining can cause

both air and noise pollution

electric generators work by

converting mechanical energy into electrical energy

which of the following is NOT a main use of fuel

solar energy, or energy from the sun is contained in

fossil fuels

which of the following would NOT likely be mined using solution mining

gypsum

acid mine drainage

harms or kills aquatic life

gangue minerals

collapse of _____ can lead to subsidence

pillars in abandoned mines

reclamation is the process of

returning land to its original or better condition arter mining

the energy needs for the united states in the 1900s have

risen slightly

a nuclear reactor is

surrounded by a thick pressure vessel that is filled with a cooling fluid

coal is formed when

swamplands are buried by sediment. the added weight creates heat and pressure that converts the plants to coal
