Science Review - Impacts on Global Climate Flashcards
Ocean water and rain droplets can absorb carbon dioxide, resulting in a slight acidification. True or False?
True
What is the greenhouse effect?
The warming of a planet due to trapped radiation.
How do volcanic eruptions influence climate?
They decrease the amount of sunlight reaching the Earth’s surface
Which of the following is a result of a meteor impact on Earth’s climate?
Release of dust and aerosols that block sunlight
What is one effect of releasing greenhouse gases into the atmosphere?
Influencing climate change
Water Vapor, Carbon Dioxide, Methane, and Nitrous Oxide are called
Greenhouse Gases
Which natural event can cause a temporary cooling effect on the Earth’s climate?
Volcanic Eruptions
How does urbanization contribute to climate change?
By increasing CO(2) emissions and raising average temperatures in urbanized areas
What happens to the temperature if more greenhouse gases are released into the atmosphere?
Temperature goes up
What human activities result in more greenhouse gases being present in the atmosphere?
Burning Fossil Fuels, Urbanization, Deforestation
Why does cutting down trees increase global warming?
Trees soak up carbon Dioxide and removing them causes more carbon to stay in the atmosphere
What natural events are a source of Carbon Dioxide?
Decomposing plants and animals, wildfire, volcanic eruption
The MAIN human activity that releases greenhouse gases is…??
Burning Fossil Fuels
What is a direct consequence of meteor impacts on the climate?
Blocking of sunlight by dust and aerosols
What is true about Urbanization?
It increases average temperatures in the area because of tree loss, factories, and more automobile
What is true about Deforestation?
It increases the amount of CO(2) in the atmosphere because plants absorb CO(2)
What is the effect of volcanic ash on the atmosphere?
It blocks sunlight, leading to cooling
What are the effects of the greenhouse effect?
-Greenhouse gases like carbon dioxide, nitrous Oxide, and Methane, trap heat in the atmosphere.
-Makes Earth much warmer than it would be without an atmosphere
-Makes Earth a comfortable place to live
Over the past 200 years, the level of Carbon Dioxide in the atmosphere has
Increased steadily
Carbon Cycle
The process of moving carbon between the atmosphere and organisms on Earth
Greenhouse Gases
Substances in the atmosphere that help trap heat near Earth’s surface
Deforestation
The purposeful clearing of forest land for materials used by humans
Photosynthesis
The process of converting sunlight into a usable form of energy
Climate Change
Long term shifts in temperature and weather patterns
