Chemistry of the Atmosphere/Using Resources random revision pages 157-165 Flashcards
Describe one likely similarity between Earth’s early atmosphere and the atmosphere of Mars today?
Earth’s early atmosphere may have been mostly carbon dioxide with little or no oxygen, which is like the atmosphere of Mars today
Which gas in the Earth’s early atmosphere dissolved in the oceans to form carbonates which precipitated as sediments?
Carbon Dioxide
Which two fossil fuels are formed from the remains of plankton?
Crude Oil and Natural Gas
How does an increase in the amount of waste going to landifll sites affect the amount of greenhouse gasses in the atmosphere?
More waste going to landfill sites means that more carbon dioxide and methane are released when the waste in the sites breaks down.
Give one way in which climate change could lead to increased flooding?
any one from e.g.
An increase in global temperature could lead to the polar ice caps melting, causing a rise in sea levels.
Changes in rainfall patterns may cause some regions to get too much rain
How might climate change effect storms?
They may become more frequent and severe.
Explain how using renewable energy sources helps to reduce the carbon footprint of a process?
It reduces the amount of greenhouse gasses that are released.
Give one reason why individuals may not make changes to reduce their carbon footprint?
Any one from e.g.
They don’t want to
They dont understand why making changes is important
They don’t know how to make changes
Under what conditions do hydrocarbons undergo incomplete combustion?
When there’s not enough oxygen available for all the fuel to burn.
Explain why breathing in particulates of soot (carbon) is bad for your health?
They can get stuck in the lungs and cause damage, leading to respiratory (breathing) problems
How do particulates cause global dimming?
They reflect sunlight back into space, meaning that less light reaches the earth
Why does burning fossil fuels often release sulfur dioxide?
some fossil fuels contain sulfur impurities
