Climate Change 1
What gasses trap the sun's heat?
greenhouse gasses
These regions of the Earth that are experiencing the most dramatic changes due to climate change.
the arctic regions have the greatest temperature change to achieve, as frozen becomes liquid, white surfaces become dark, and more heat is absorbed, their range changes more
What is climate change?
a change in global or regional climate patterns, and the many negative results that can ripple out from changes in temp and global water distribution
What process naturally removes carbon dioxide from the atmosphere.
photosynthesis
Fossil fuels are a renewable resource.
True or Falsle
False
Why is the increase of Greenhouse gasses a big issue?
These gasses absorb heat and increase the average temperature of Earth over time, resulting in other severe concerns
Which two green house gases contribute the most to global warming?
Carbon dioxide and Methane
Which country is presently emitting the most CO2 due to its huge land mass and population, and huge production of coal burning electrical facilities?
China
Oil, coal and natural gas
What are 3 examples of fossil fuels?
The average weather for a region over a long period of time is. _______________.
Climate
Heating and cooling are significant contributors to energy consumption, accounting for nearly half of residential energy use. Connect the dots about how heating and cooling contribute to potential changes in earth's temperature.
Most Heating and cooling either burns fossil fuels (heating) or use electricity that in many cases comes from coal burning steam plants. So Much heating and cooling=much greenhouse gas production
How do green house gases cause the Earth's temperature to rise?
They absorb the sun's radiation and trap heat within the atmosphere
These are three types of greenhouse gases.
What are carbon dioxide, methane, and water vapor?
What would be Earth's temperature without green house gases? (without any atmosphere at all...)
Earth's temperatures would be cold, oceans would freeze(without any atmosphere at all, it would be frozen and uninhabitable)
All of the radiation from the sun is absorbed by the Earth.
True or False
False
What is the greenhouse effect?
Certain gasses in the atmosphere trap heat and warm the Earth, like a greenhouse holds in heated air and moisture
Burning these contributes to global warming.
Burning fossil fuels
This uncontrolled fire spreads rapidly, often igniting in forests, grasslands, or other dry areas. It can be fueled by high winds and dry conditions, and is a frequent threat in places like California and Australia.
Wildfires
How can global warming cause sea levels to rise?
Melting glaciers and ice caps release more liquid into the oceans and other waterways, possibly raising their levels, and making storm flooding worse
The dry arid conditions of long-term drought that cause an area to become a desert.
Desertification
What activities are the largest contributors of greenhouse gases in the world?
Burning fossil fuels
What do we call the large-scale act in cutting down trees and other shrubbery.
deforestation
List two of the environmental impacts of climate change.
poverty and displacement
a warming, rising ocean
increased drought
hotter temperatures
loss of species
not enough food
How can we as humans minimize the amount of green house gases we emit into the atmosphere?
drive less / use public transportation
unplug-- various ways to use less electricity
composting, reduce, reuse, recycle,
eat locally grown, or grow our own food
Since when have human activities become the main driver of climate change?
The Industrial Revolution
