The movement of thermal energy through liquids and gases.
The transfer of thermal energy by direct contact between objects.
Thermal energy that travels in waves and can pass through empty space as well as some objects.
Fossil Fuels formed from living organisms.
coal, oil and natural gas
Greenhouse Effect
specific gases in the atmosphere (expecially water and carbon dioxide)that absorb the heat that is leaving the planet and thereby keeps Earth warmer.
Global Climate
Earth's pattern of temperature and precipitation.
Feedback Loops
one way that parts of a system influence each other. Reinforcing feedback loops can cause radical change in ecosystems.
Law of Conservation of Energy
Energy always remains constant in amount. Energy is neither created nor destroyed.
Two ways that energy sources are classified as are:
Renewable energy and Nonrenewables energy
Energy sources that exist in fixed amounts are:
Nonrenewable energy
Energy sources that can be replenished through natural, or resource managemnet practices are:
