Properties of water
Is water polar or non polar?
Polar
Snow, sleet, hail are all examples of what stage of the water cycle?
Precipitation
What is a carbon sink/ reservoir and what is a carbon source?
Carbon sink stores carbon a carbon source releases carbon.
What is nitrogen fixation?
Turning atmospheric nitrogen into usable nitrogen.
What is the largest carbon sink?
Oceans
Which side of water is more negative?
Oxygen
What is it called when liquid water turns into gas form?
evaporation
What are fossil fuels?
Non-renewable energy created from dead organic materials.
What are the two main ways nitrogen from the atmosphere get oxygenated.
Through bacteria or lightning
What is the most used form of nitrogen in plants?
NO3 - Nitrate
What is cohesion?
Water sticking to water
What is the four main stages of the water cycle?
Evaporation, condensation, precipitation, run-off
How do plants contribute to the carbon cycle?
Through photosynthesis they absorb CO2 from the atmosphere and release some back into the atmosphere at night during respiration.
What is denitrification
some nitrogen returns back into the atmosphere by bacteria
Why is water the universal solvent?
Because it dissolves more substances than any other liquid.
What is surface tension and what property of water causes it?
Water being able to resist an external force due to cohesion
Define run-off.
Excess water from soil, roads, sidewalks that gets sent back into large bodies of water such as oceans lakes or ponds.
During respiration, living things break down _________ , releasing CO2 back into the atmosphere.
glucose
What is immobilization?
Microorganisms making usable nitrogen unavailable to plants temporarily until they die.
What element is commonly found in fertilizers?
Nitrogen
What is capillary action and what two properties of water contribute to it?
Water pulling water along a surface. This is due to cohesion and adhesion.
Clouds form through condensation and warmer less dense air keeps them suspended. What cloud type is the most common for causing thunderstorms?
Cumulonimbus
Decomposition releases carbon by the break down of what?
dead organic materials
What happens when too much nitrogen get into the water?
algal blooms
What happens to the ocean with increased carbon levels?
the ocean becomes acidic, this leads to organisms death and coral bleaching.
