Earth's Spheres
This sphere includes all living things on Earth
What is the biosphere?
The process where water vapour cools and forms clouds.
What is condensation?
This gas is most associated with the greenhouse effect.
What is carbon dioxide?
Traditional controlled burning practices by First Nations Australians are called this
What is cultural burning
What planet is known as the Red Planet?
What is mars?
Name the five spheres of the Earth
What is biosphere, hydrosphere, atmosphere, lithosphere, cryosphere
This process releases energy from glucose inside cells.
What is cellular respiration?
The greenhouse effect helps keep Earth at a temperature that can support this.
What is life?
Cultural burning usually uses fires that are this intensity.
What are low-intensity/cool burns
How many bones does an adult human body have?
What is 206?
This sphere acts as the largest carbon reserviour on Earth.
What is the lithosphere?
State the word equation for respiration?
What is glucose + oxygen = carbon dioxide + water + energy
This human activities is one of the largest contributors enhanced greenhouse gas emissions worldwide.
What is combustion?
One purpose of cultural burning is reducing the risk of these dangerous events.
What are severe bushfires?
What is the most abundant gas in the Earth's atmosphere
What is nitrogen
Which sphere is MOST responsible for regulating weather patterns and why?
Explain how water moves from the ocean to rain over land.
What is evaporation -> condensation -> precipitation
Why would Earth become too cold for most life without greenhouse gases?
What is greenhouse gases trap heat in atmosphere to keep Earth warm enough for life
Explain how cultural burning helps transfer nutrients through an ecosystem.
Burning dead plant material returns nutrients to the soil as ash, supporting new plant growth.
This scientist developed the theory of relativity.
Who is Albert Einstein?
Why are Earth's sphere's considered interconnected systems rather than seperate parts?
What is changes in one sphere affecting the others because matter and energy constantly move between them?
Explain how photosynthesis moves carbon between spheres.
What is plants taking in carbon dioxide from the atmosphere and store it as glucose in the biosphere
Explain how combustion affects both the carbon cycel and Earth's energy balance
Combustion releases stored carbon dioxide into the atmosphere, disrupting the carbon cycle. The extra greenhouse gases trap more heat, changing Earth’s energy balance to retaining more heat and causing global warming.
Explain how cultural burning can reduce greenhouse gas emissions
Low-intensity burns prevent massive high-intensity bushfires, which release much larger amounts of carbon dioxide and methane.
Lightning is hotter than the surface of this celestial object.
What is the sun?
