POSITIVE AND NEGATIVE EFFECTS BY HUMAN
ACTIVITIES
• Humans have made changes to behavior in protect Earth’s resources.
• Energy is transferred by conduction, convection, and radiation. Electromagnetic waves interact with
different materials by reflecting, refracting, absorbing, and transmitting.
• The greenhouse effect keeps Earth at a livable temperature by keeping radiating energy within Earth’s
atmosphere. All matter is made of atoms and molecules of atoms. Substances have unique physical and
chemical properties including the movement of molecules in response to a change in temperature and
phase change.
• Chemical reactions occur between substances to form new substances.
• Climate is the historical pattern of weather for an area. When aspects of an ecosystem change some
organisms will adapt, some will die, some will leave, and new organisms will move into the ecosystem.
• A change in the global mean temperature of Earth will effect humans and other organisms in many
ways.
GLOBAL WARMING VS. GREENHOUSE EFFECT
• Global warming refers to the fact that the surface of the
Earth is getting hotter.
• The greenhouse effect refers to the fact that earth is
warmer with an atmosphere than is would be without it.
OCEAN ACIDIFICATION
• Ocean acidification is the ongoing decrease in the
pH of the Earth's oceans, caused by the uptake of
carbon dioxide (CO2) from the atmosphere.
