Science Unit test(Climate Change) Flashcards
Definition of weather
Atmospheric conditions of an area over a short period of time.
Climate
Atmospheric conditions of a region over a long period of time.
Describe weather
Temperature, wind, precipitation, humidity
what is the day and night circle caused by
by the tilt(23.5 degrees) of the earth around its axis
what are climatographs
a graph that displays average (mean) precipitation and temperature for an area. It is used to compare the climate in different places
What is the most important factor affecting the climate change
Global Warming
What are the main greenhouse gases in our atmosphere??
Nitrogen, Carbon and methane
What is climate change
Global warming is the long-term heating of Earth’s surface
Define Albedo effect
an expression of the ability of surfaces to reflect sunlight (heat from the sun).
how does the albedo effect affects the surface temperature
Low albedo (dark surfaces) leads to higher uptake of energy and, hence, warming.
We know that the overall temperature of the Earth is
Increasing
is negative feed back slowing down the climate change
yes
there is a rise in the sea levels by ____ in the past 100 years
10-15 cm
In the summer, Canada experiences more hours of daylight and warmer temperatures than in the winter. Explain this difference.
the sun’s angle is more perpendicular to us than at other times of year.
Explain why the greenhouse effect and global warming are NOT the same thing.
The greenhouse effect is a natural phenomenon and beneficial to life on Earth. However, global warming is produced as a consequence of the combustion of fossil gases expelled by industry, livestock, vehicles and other terrestrial elements, which generate an increase in global temperature.
