19-1 Section Review
Cycles of Matter
Pg 511 (1-8)
Question Number One
• Directions: For each pair of terms, explain how the
meanings of the terms differ.
Evaporation: The Sun’s heat causes water to change
from liquid to vapor (Liquid Gas)
Condensation: Water vapor cools and returns to a
liquid state (Gas Liquid)
How are they different??? They are OPPOSITE!!!
Question Number Two
• Directions: For each pair of terms, explain how the
meanings of the terms differ.
Decomposition: The breakdown of substances into
simpler molecules
Combustion: Process of burning a substance.
How are they different? Both break down matter, but
Combustion burns and Decomposition is done
through bacteria or fungi.
Question Number Three
•
Nitrogen Fixation:
a.
b.
c.
d.
Is done only by plants
Is done mostly by bacteria
Is how animals make proteins
Is a form of decomposition
Answer: B. is done Mostly by bacteria (Converting
Nitrogen to Gas section on pg 510)
Question Number Four
• Describe the Water Cycle:
– Answer:
• The movement of water
between the oceans,
atmosphere, land and living
things
• Phases Include: Evaporation,
Condensation, Transpiration,
Precipitation
Problems with Most Answers:
We already KNOW it’s a Cycle
of Water!! BUT DESCRIBE the
cycle!!!
Question Number Five
• Describe the Carbon Cycle:
– Answer:
• The exchange of carbon between the
environment and living things
• Begins with
photosynthesisAnimals and
MicroorganismsAir through
Respiration, Decomposition, and
Combustion\
Problems with Most Answers:
1. Like #4 we already know it is a
cycle, but what are the steps? What
does it do?
Question Number Six
• Question: The Average Person in the United States uses about 78 gal of water
each day. (A) How many liters of water does that equal? (B) How many liters of
water will the average person use in a year?
• Answer:
– Facts You Need to Know:
• 3.8 Liters in ONE Gallon
• 365 Days in ONE Year
A: 78 Gallons of Water X 3.8 Liters/Gallon = 296 Liters of Water
B: 296 Liters X 365 Days = 108,186 Liters/Year
Problems with Most Answer:
1. Didn’t Even Try!!!
2. Just Listed a Number!
3. Always check your agenda for conversion.
Good News!! If you tried, You got the Points! YAY!
Question Number Seven
•
Question: Draw a simple diagram of each of the
cycles discussed in this section. Draw lines
between the cycles to show how parts of each cycle
are related.
Question Number Eight
• Question: Give an example of how the
calcium in an animal’s bones might be cycled
back into the environment.
• Answers:
– A carnivore might eat a herbivore and get
calcium by chewing on its bones
– Decomposition breaks down the bones and
returns the calcium back to the environment
