Energy Conversion Quiz

Wind energy = Energy harnessed from the movement of air Geothermal energy = Energy derived from the heat within the Earth Biomass energy = Energy generated from organic materials such as wood, agricultural crops, and waste Tidal energy = Energy obtained from the gravitational pull of the moon and the sun on the Earth's water bodies

Coal = Fossil fuel formed from plant matter that lived millions of years ago Oil = Fossil fuel derived from ancient marine organisms Natural gas = Fossil fuel primarily composed of methane and other hydrocarbons Nuclear energy = Energy released from nuclear reactions, typically involving the splitting of atoms

Solar energy = Advantages: abundant, renewable; Disadvantages: intermittent, expensive technology Hydroelectricity = Advantages: renewable, low greenhouse gas emissions; Disadvantages: impacts on aquatic ecosystems, limited by geography Biofuel = Advantages: renewable, reduces greenhouse gas emissions; Disadvantages: competition with food production, land use concerns Wave energy = Advantages: abundant, renewable; Disadvantages: infrastructure challenges, environmental impacts on marine life

<p>Joule = Unit of energy equivalent to the work done by a force of one newton when its point of application moves one meter in the direction of the force Renewable energy = Energy derived from sources that are naturally replenished on a human timescale Nonrenewable energy = Energy derived from sources that are finite and cannot be replenished at the same rate as they are consumed Fossil fuel = Natural fuel formed from the remains of living organisms, such as coal, oil, and natural gas</p> Signup and view all the answers

<p>Hydrogen fuel cells = Devices that generate electricity by combining hydrogen and oxygen electrochemically Ocean thermal energy conversion = Technology that utilizes the temperature difference between deep and shallow waters to generate power Wind turbines = Machines that convert the kinetic energy of wind into mechanical power Geothermal power plants = Facilities that harness heat from the Earth's interior to produce electricity</p> Signup and view all the answers
