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
Rising global temperatures are causing Arctic sea ice to do this.
melt (or melting)
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
The melting of this permanently frozen ground in the Arctic releases greenhouse gases like methane and carbon dioxide.
Permafrost
What are 3 examples of fossil fuels?
Oil, coal and gas
The average weather for a region over a long period of time is. _______________.
Climate
Loss of sea ice threatens this iconic Arctic predator that depends on ice platforms to hunt
polar bear
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.
carbon dioxide, methane, and ozone
What is climate change?
a change in global or regional climate patterns
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.
Wildfires
How can global warming cause sea levels to rise?
Melting glaciers and ice caps
This reflective surface in the Arctic helps keep Earth cool by bouncing sunlight back into space, but it’s shrinking rapidly due to warming.
Sea ice
Name at least two types of renewable energy.
Solar, wind, geothermal, biomass, hydropower, biomass and more
What do we call the act in cutting down trees and other shrubbery.
deforestation
This greenhouse gas, about 80 times more powerful than CO₂ over 20 years, can be released when thawing permafrost decomposes organic matter.
methane
What is the difference between weather and climate?
Weather refers to short-term atmospheric conditions (like temperature, wind, or precipitation on a given day), while climate describes the long-term average patterns of weather in a region over many years or decades.
Scientists say the Arctic is warming about four times faster than the rest of the planet, a phenomenon known as this amplification effect.
