Which of the following does NOT happen to solar energy when it reaches Earth?
Some solar energy reflects off the atmosphere, back to space
Some solar energy passes through Earth and comes out the other side
Some solar energy is absorbed by land and water
Some solar energy is radiated from the Earth's surface and trapped by the atmosphere
How is the greenhouse effect produced?
When solar energy trespasses the atmosphere.
When some energy is reflected back to earth.
When the green house is burned.
When the sun doesn't emit radiation.
The greenhouse effect is about
warming the atmosphere because of increased CO2 levels
warming the atmosphere because of decreased CO2 levels
cooing the atmosphere because of increased CO2 levels
cooling the atmosphere because of decreased CO2 levels
The greenhouse effect is caused by
more heat arriving at the Earth from the sun
the Earth releasing more heat at night
gases in the air trapping heat released by the Earth
The graph shows us that
the earth temperature is always increasing
the earth's temperature has steadily increased since 1900
the earth's temperature has steadily rising since the 1960s
the earth's temperature decreased during the 19th and 20th centuries
The greenhouse effect comes from
all heat being released by the earth going back into space
some of the heat heat being released by the earth going back into space
some of heat being released by the earth being trapped in the air
all of heat being released by the earth being trapped in the air
The area of human activity responsible for the highest greenhouse gas emissions is
energy supply
transport
agriculture
industrial
The area of human activity responsible for the second highest greenhouse gas emissions is
residential activity
transport
agriculture
industrial
From the information in the graph we can say that:
power stations produce about 1.5 times the emission of residential activities
residential activities produces about the same amount of emissions as waste disposal
fossil fuel retrieval produces more emission than transportation of fuels
industrial process produce about 5 times the emissions of waste disposal & treatment
The highest gaseous pollutant is
methane
nitrous oxide
carbon dioxide
fluorinated gases
Why do the stars appear to rotate around the sky?
Because the Earth is spinning
Because the stars are spinning
Because you are dizzy
They're not, it is an illusion
What was the ancient Greek answer to the question of why are the stars moving across the sky?
They thought the stars were moving
They thought the Earth was moving
They didn't really notice it
They thought the stars were a herd of turtles
What was the problem with the Greek explanation?
Planetos, which moved back and forth across the night sky
there wasn't a problem
They could feel the earth spinning
They realized turtles can't fly
How did the Greeks try to address the problems in their model
They created even more complex models
They thought that maybe some turtles so have wings hidden under their shells
They decided that the earth must be the spinning

All matter emerged from a massive black hole at the center of the universe.
