Earths' Spheres
Earth's surface "land" is part of what sphere
Geosphere
In what spheres do humans and animals need to stay alive?
Biosphere and Hydrosphere
What element is cycled through Earth’s systems?
carbon
What gas traps heat in the atmosphere?
Carbon dioxide
Main storage of carbon in plants
Glucose
The sphere with multiple layers is called....
atmosphere
Wind blows on rocks which cause rock slides
Atmosphere and Geosphere
What process absorbs carbon dioxide from atmosphere?
photosynthesis
What keeps Earth warm enough for life?
Greenhouse effect
Name the two reactants of cellular respiration
oxygen and glucose
Fish are part of which sphere?
Biosphere
Air blows on water creating waves and surface currents.
Atmosphere and Hydrosphere
Name one process that releases CO2 into the atmosphere.
Cellular respiration
What kind of radiation is trapped?
Infrared
Glucose chemical formula
C6H12O6
Beach is part of which sphere?
Geosphere
Water weathering away at rocks
Hydrosphere and Geosphere
What type of rock stores carbon long-term?
limestone
What fuel type causes most carbon emissions?
Fossil fuels
Chemical equation for photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This is not the air but what sphere do many members of the biosphere need to survive
hydrosphere
Surface water evaporates and goes into the troposphere where the water condenses into clouds until it's too dense and comes down in rain (precipitation) which waters plants.
Atmosphere, Hydrosphere, and Biosphere
What human activity increases atmospheric carbon?
combustion
What human process most accelerates this?
Industrialisation
Chemical equation for cellular respiration
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
