Greenhouse Effect
What three gases are part of the greenhouse effect?
What is conduction?
Heat transfer through vibration or contact
All objects emit and absorb ______.
Infrared Radiation.
The atomic number tells you...
the amount of protons (and electrons) an element has
What type of transfer occurs when the handle of a metal spoon get hot when you leave it in water.
Conduction
Evidence of global warming include
rising sea level increased concentration of greenhouse gases melting glaciers and sea ice
what is convection?
heat transfer through movement, warm currents rise up
What factor contributes to how much radiation an object emits?
Temperature. (the hotter an object- the more IR)
what is the charge of neutron, protons, and elctrons?
neutrons=neutral, protons=Positive, electrons=negative
What type of transfer occurs when roasting marshmallows on an open fire?
Infrared Radiation
Effects of global warming on weather
heat waves and droughts increased flooding from mor intense, frequent, and heavy rain
what occurs when two objects of different temperature are in contact with each other?
conduction
