Earth's Processes: Climate change Study Guide
In industry, indirect emissions of greenhouse gases are emissions produced
by burning fossils fuels off-site to make electricity that is used on-site.
What is a major impact of climate change for fish species?
changes in ocean habitat
Which agricultural practices result in methane emission? Select the two correct answers.
manure management techniques and rice cultivation
Which effect of temperature rise causes a feedback resulting in a rise in global temperatures?
more water vapor in the atmosphere
How does climate change affect energy in the atmosphere?
Decreased ice causes less energy to be reflected.
What is Ozone?
A gas composed of molecules with three oxygen atoms
Why should a model of the carbon cycle include the burning of fossil fuels?
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Which of the following factors contribute to the periodic changes in Earth's temperature known as the Milankovitch cycles? Select the three correct answers.
Earth's axial tilt varies between 22 and 24 degrees ; Earth's orbit alternates between a circular and an elliptical shape ; Earth wobbles slightly on its axis
Drag each item to the correct location to show when each occurred.
Event that occurred billions or millions of years ago: Oxygen builds up. Event that occurred thousands of years ago: The last ice age. Event that occurred decades ago: carbon dioxide
Joshua trees cannot germinate and grow as easily in today's warmer climate. Which of these actions would be most likely to help the species survive climate change?
Growing in a range farther north

Increased ; 400 ; 150
What does a wider tree ring indicate, as opposed to a thinner tree ring?
It indicates that the weather that year was warm and wet.
Scientists believe that the _____ explain why Earth's _____ has fluctuated between glacial periods and interglacial periods.
Milankovitch cycles ; climate
Drag each item to indicate whether it supports ocean acidification or ocean warming.
Ocean Acidification Evidence: Difficult for some species to make shells , larger concentration, organisms prone to illness . Ocean warming evidence: Melting of glaciers, expansion of ocean volume, growing difficulty in absorbing
Identify the way oceans can influence climate change. Select the two correct answers.
Ocean temperature could affect currents ; Ocean currents could affect prevailing winds.
What tool gives scientists the best data to study ice loss near the poles?
Satellite measurements
What does a model of the rock cycle show?
The amount of Earth's carbon is constant.
In terms of climate change, what do cherry blossoms and sugar maple trees have in common?
They are affected by earlier spring warmth.
Which factor should be included in a model of energy flow into the atmosphere?
concentrations of greenhouse gases
Which of the following is the main cause of increased burning of fossil fuels?
economic and population growth
Why do higher temperatures often result in greater precipitation?
higher temperatures stimulate evaporation
Which action can help reduce the rate of global warming?
reducing emissions from cars
Which indicator would tell scientists the most about future climate change?
the data obtained from ice cores
The glass in a greenhouse is _____ to visible light and _____ to infrared wavelengths. The same can be said for greenhouse gases.
transparent ; opaque
