B&E GRADE A QUESTIONS AND AN
What is a fundamental difference between the water cycle and other nutrient cycles? -
(correct answer)The difference is that the nitrogen cycle, and the carbon cycle include
chemical changes, which is when it changes and does something else, but the water
cycle doesn't. The water cycle is a physical change, which is a change in its form.
What is the water cycle? - (correct answer)The water cycle has 4 steps. First, the water
goes through evaporation or transpiration(plant sweat) from the ocean and collects in
the clouds. Then, the the water cools down in the clouds causing condensation (gases
back to liquids). Then, precipitation, like snow or rain, happens, where the water meets
the ground again. Finally, the water goes back underground into aquifers or, becomes
surface runoff.
What are two ways water returns to the atmosphere? - (correct answer)It enters the sky
through evaporation or transpiration. It gets back to the ground by precipitation like rain,
snow or hail.
How does water get from the atmosphere back to land? - (correct answer)Through the
process of precipitation, like snow, hail or rain.
What are two types of carbon? What type is carbon dioxide (CO2)? What is an example
of the other type? - (correct answer)The two types of carbon dioxide are organic and
inorganic. CO2 is inorganic. An example of organic carbon dioxide is amino acids and
proteins.
How can carbon aid the spread of toxic substances? - (correct answer)It can bond with
pesticides or other toxic metals. This allows the carbon to facilitate the transportation of
the chemicals and makes it easier for animals to take them in.
Why is monitoring the levels and the forms of carbon in streams important to
maintaining safe drinking water? - (correct answer)Drinking water can contain many
different diseases so we need to check the quality of the water to make sure it is safe. It
