Carbon Cycle
Exists in many forms, such as in carbon dioxide, glucose, proteins, starch, coal, fossil fuels, etc
what is the carbon?
Gases that trap heat in the atmosphere
what are greenhouse gases?
dissolves in water (from the atmosphere) to form acid
what is carbon dioxide?
The colour that absorbs the most heat
What is black?
The uneven heating of the Earth
How is wind formed?
Oxygen reacts with glucose (sugar) to produce carbon dioxide, water and energy.
What is cellular respiration?
Reaches the Earth's surface and heats the land and oceans.
what is solar radiation?
What shelled marine organisms are composed of
What is calcium carbonate?
The colour that reflects the most heat
What is white?
A current of air that forms where air from 2 different cells rises or falls
What is a jet stream?
The formation of coal, oil & natural gas. When burned, carbon dioxide is released into the atmosphere.
What are fossil fuels?
The greenhouse gas with an atmospheric lifespan of about 12 years.
What is methane?
decreases with an increased carbon dioxide concentration
what is pH?
Feedback with the same input and output
What is positive feedback?
allows warm air to move north or cold air to move south
What is an unstable jet stream?
Can be completed within a few years, moving substances (carbon) from the atmosphere to the biosphere, then back to the atmosphere.
What is the fast carbon cycle?
Increases the amount of GHGs in the atmosphere
What are the burning of fossil fuels?
Serves as a food source for coral reefs, but are expelled from their tissues when stressed.
What are symbiotic algae?
Feedback with an opposite input and output.
What is negative feedback?
currents circulate water through the world's oceans, carrying heat from the tropics toward the poles and sending colder water back in deep ocean currents
What is the thermohaline circulation?
Takes millions of years to complete, moving substances (carbon) through the Earth's crust between rocks, soil, the ocean and the atmosphere.
What is the slow carbon cycle?
The carbon cycle being altered by increased carbon emissions, resulting in an enhanced greenhouse effect.
What is the fast carbon cycle?
Ions that bond with excess hydrogen ions
What are carbonate ions?
The Arctic is losing this and absorbing more heat.
What is ice cover?
Causes cold, salty water to sink and warm, less salty water to rise.
What is density?
