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
What is climate change?
a change in global or regional climate patterns
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?
It causes climate change and increase in the global temerature
Which two green house gases contribute the most to global warming?
Carbon dioxide and Methane
Which country is presently emitting the most CO2?
China
Oil, coal and gas
What are 3 examples of fossil fuels?
The average weather for a region over a long period of time is. _______________.
Climate
what's the difference between weather and climate
weather takes place over a short period of time (days/weeks) and climate takes place after a long time (decades/centuries)
How do green house gases cause the Earth's temperature to rise?
They absorb the sun's radiation and trap heat
These are three types of greenhouse gases.
What are carbon dioxide, methane, and ozone?
What would be Earth's temperature without green house gases?
Earth's temperatures would be cold, oceans would freeze
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
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
what does anthropogenic mean
originating in human activity
What activities are the largest contributors of greenhouse gases in the world?
Burning fossil fuels
What do we call the act in cutting down trees and other shrubbery.
deforestation
List the mentioned 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 amout of green house gases we emit into the atmosphere?
drive less / use public transpo
unplug
composting
what is El Nino
the warming of the oceans surface, above average sea temperatures usually in the central and eastern tropical pacific ocean
