The Global Spheres
What are the four global spheres?
Atmosphere, Biosphere, Lithosphere, Hydrosphere.
What is the main human activity causing climate change?
Burning fossil fuels
How many siblings does Miss Lyons have?
2
What galaxy is Earh located in?
The Milky Way
What type of graph is typically used to show CO₂ levels over time?
Line graph.
Which sphere includes all living things?
The Biosphere
Name one greenhouse gas other than CO₂.
Methane, nitrous oxide, water vapour.
Where is Miss Lyons from?
Innisfail
What force keeps planets in orbit around the Sun?
Gravity.
What is one sign of good data quality?
Consistent intervals, large sample size, reliable source.
How does deforestation affect at least two spheres?
Removes trees (biosphere), increases CO₂ in atmosphere, causes soil erosion (lithosphere).
Why is the greenhouse effect important for life on Earth?
It keeps Earth warm enough for life.
How many times has Miss Lyons been outside of the country?
1
Why do we see different constellations in different seasons?
Earth’s orbit around the Sun
What trend is shown in most global temperature graphs?
Temperatures are increasing (warming trend).
Explain how the hydrosphere and atmosphere interact to create weather.
Water evaporates (hydrosphere), forms clouds and precipitation (atmosphere).
Explain the difference between the greenhouse effect and the enhanced greenhouse effect.
Greenhouse effect = natural warming; enhanced = human-caused increase in warming.
What sport has caused all of Miss Lyons's injuries?
Netball
Explain why lunar eclipses don’t happen every month
The Moon’s orbit is tilted relative to Earth’s orbit
How are correlation and causation different?
Correlation = relationship; causation = one thing directly causes another.
Describe one example of how human activity impacts all four spheres.
Burning fossil fuels → increases CO₂ (atmosphere), warms oceans (hydrosphere), changes habitats (biosphere), requires mining (lithosphere).
Describe two pieces of evidence scientists use to demonstrate climate change.
Ice core data, rising CO₂ levels, global temperature increase, sea-level rise, shrinking glaciers.
Where does Miss Lyons partner work?
Kirwan State High School
Describe how light-years are used in astronomy.
They measure distance, not time — the distance light travels in one year.
Sea level and global temperature graphs both rise. Explain one scientific causal link between them.
Higher temps melt ice caps + expand ocean water → sea levels rise.
