Climate Flashcards
What is the name given for a cooling period in Earth’s history?
Glacial Period
What are the 4 natural causes of climate change?
Asteroid Collisions, Volcanic Activity, Orbital Theory, Solar Activity
How has volcanic activity impacted upon the Earth’s climate in the past?
Ash blocks the suns rays so it cools down Earth
What are 3 pieces of evidence for natural climate change?
Ice Cores, Tree Rings, Historical Records
How do historical records provide evidence for past climate change?
Painting, newspapers and religious records provide us information about past climate change e.g. frost fairs on the River Thames
What is the greenhouse effect?
Carbon Dioxide gets trapped in the atmosphere which acts like a blanket to warm the Earth
Name 4 human activities which enhance the greenhouse effect?
Industry, Transport, Energy, Agriculture
What are 3 pieces of evidence for human - induced climate change?
Global temperature records, Rising sea levels, Increased extreme weather events
What are the 2 reasons for global sea level rise?
Thermal Expansion, Ice caps melting
Name 3 consequences of climate change
Famine, Frequent Droughts, Coastal Flooding
Why is it difficult to make projections of how much sea levels could rise by?
We don’t know the future population so we don’t know how many greenhouse gases we will be producing.
Why is the equator the hottest part of Earth?
The suns rays are more concentrated there
When warm air rises, what is the pressure?
Low pressure
When cool air sinks, what is the pressure?
High pressure
What is the climate of the Equator?
Warm and Wet
