8th SCIENCE RECENT CLIMATE CHANGE = LESSON 3- KEY CONCEPT BUILDER

QuestionAnswer
CLIMATE a global_________model or GCM is a set of complex equations that is used to predict future climates.
GREENHOUSE GASES GCMs include the effects of___________________ ________and oceans in their calculations.
PRECIPITATION GCMs combine mathematics with the laws of physics to predict temperature amount of_____________________ when speeds and other characteristics of climate model.
CLIMATE MODEL GCMs combine mathematics with the laws of physics to predict temperature amount of precipitation wind speeds and other characteristics of ________________ _______________.
MAPS the calculations are displayed as _________________________
SUPERCOMPUTERS Scientist used powerful________________to solve complicated mathematical equations.
EQUATIONS a global climate model or GCM is a set of complex ___________that is used to predict future climates.
PHYSICS GCMs combine mathematics with the laws of _________ to predict temperature amount of precipitation when wind and other characteristics of climate model
TEMPERATURES by the year 2100_______________are expected to rise by between 1℃ and 4℃.
GLOBAL WARNING most GCMs predict that_____________is closely related to greenhouse gases emissions.
POLAR the ______________regions are expected to warm more than the tropic regions.
TROPIC the polar regions are expected to warm more than the _____________ regions.
WHAT IS GLOBAL WARMING? the rise in Earth's average surface temperature.
WHAT DID THE INTERGOVERNMENTAL PANEL ON CLIMATE CLIMATE CHANGE CONCLUDE IN 2007? most of the temperature has been increased by human activities.
WHAT ARE THREE GREENHOUSE GASES? Carbon Dioxide, methane, water vapor.
WHAT ARE NATURAL SOURCES OF CARBON DIOXIDE IN THE ATMOSPHERE? volcanic eruptions, forest fires, and cellular respirations.
WHAT EFFECT DOES BURNING FOSSIL FUELS HAVE ON THE ATMOSPHERE? Carbon dioxide enters the atmosphere when fossil fuels are burned.
WHAT ARE TWO WAYS IN WHICH DEFORESTATION INCREASES THE LEVELS OF CARBON DIOXIDE IN THE ATMOSPHERE? 1. when forests are cut down trees no longer use carbon dioxide, 2. wood left rots and releases more carbon dioxide.
HOW DO AEROSOLES EFFECT CLIMATE? aerosols reflect sunlight back into space which prevents some of the sun's energy from reaching Earth causing cooling climate over time.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
