Which of the following are major greenhouse gases?
CO2 (Carbon Dioxide)
O3 (Ozone)
CH4 (Methane)
N2O (Nitrous Oxide)
H2O (Water Vapor)
The top three ways humans increase the concentration of atmospheric carbon are
Agriculture
Energy Production
Transportation
Mining
What can happen to sunlight that reaches Earth's surface?
It can be absorbed by Earth's surface.
It can be reradiated as heat.
It can be reflected back toward space.
all of the above
____________ is an interaction between ocean and atmosphere that has major effects on weather worldwide, such as causing rainstorms and floods in areas that are usually dry.
Thermohaline circulation
Carbon sequestration
El Niño
The greenhouse effect
In general, how do ocean currents affect Earth's climate?
They create waves that create prevailing winds.
They move heat energy from place to place.
They magnify the sun's rays and heat Earth's surface.
They are the main source of greenhouse gases.
What effect do large forests have on Earth's climate?
They take in carbon dioxide and help slow global warming.
They decrease precipitation by absorbing water from the atmosphere.
They warm the Earth by absorbing and reradiating heat energy.
They interfere with winds and prevent the global redistribution of heat.
Which of the following has caused sea levels to rise in many parts of the world?
Ocean acidification
Melting ice
Ozone depletion
Changes in global ocean circulation
What is the probable cause of global warming?
a reduction in the number of glaciers
increased greenhouse gases in the atmosphere
weakened prevailing winds
faster ocean currents
How has global warming affected life in the oceans?
Habitat is being lost as ocean water levels drop.
Ocean water temperatures have cooled to maintain balance.
Photosynthesis happens to a greater extent due to increased sunlight.
The algae contained within some corals are dying.
It is expected that, with global warming, diseases now commonly found in warm regions will soon
transmit from humans to animals.
be less contagious.
become hot spots.
spread to colder regions.
Which of the following is NOT a result of global warming?
droughts
rising sea levels
ozone hole
ocean acidity
An airplane passenger pays an organization to plant trees that will take in enough carbon dioxide to compensate for the emissions created by the passenger's flight. This is an example of a
carbon sequestration
carbon offset.
cap-and-trade program.
carbon footprint.
The ______________ is an international agreement that seeks to limit greenhouse-gas emissions.
Kyoto Protocol
Energy Star program
Environmental Protection Agency
cap-and-trade program
Scientists determine current climate conditions by
making direct measurements.
creating computer models.
examining ice cores.
using proxy indicators.
How do volcanic eruptions affect weather?
Eruptions form clouds that drop large amounts of precipitation.
Gases and particles may block sunlight and lower temperatures.
Vibrations caused by eruptions shift ocean currents, which in turn affect weather.
They cause a long-term increase in temperature.
To learn what climates were like in the past, scientists investigate the following types of indirect evidence that serve as substitutes for direct measurement.
computer models
proxy indicators
topography
carbon footprints
Which human activity contributes the most carbon dioxide to the atmosphere?
fishing
breathing
burning fossil fueels
farming
Accounts for 81.6% of all U.S. greenhouse gas emissions from human activities.
Water Vapor
Fluorinated Gases
Carbon Dioxide
Methane
Nitrous Oxide
Capturing carbon dioxide (CO2) from the atmosphere or capturing anthropogenic (human) CO2 from large-scale stationary sources like power plants before it is released to the atmosphere. Once captured, the CO2 gas (or the carbon portion of the CO2) is put into long-term storage.
Carbon dioxide
Carbon sequestration
Methane
Global warming
