An increase in livestock increases which greenhouse gas?
Methane
Sunny, 45oF, windy and light rain in the afternoon.
weather
When a woman that is 9 months pregnant receives the message to release the hormone oxytocin into the bloodstream, and then as a result the hormone causes her cervix to dilate, which then results in the release of more oxytocin.
Positive feedback loop
True or False: The melting of glaciers is the main cause of sea level increase.
True
What is the name of the process in which plants remove carbon dioxide and the process in which animals release it into the air?
photosynthesis and cellular respiration
What are two reasons carbon dioxide is the greenhouse gas that scientists are most focused on?
1. It lasts the longest in the atmosphere (20-200 years).
2. It is caused by human activity and can be controlled.
Three factors that cause an increase in average global temperature increase.
1. Greenhouse gasses
2. Deforestation
3. Albedo Effect
This feedback loop reacts to a stimulus by counteracting it and putting the system back to setpoint.
Negative feedback loop
Natural hazards are predicted to increase over the next ____ years if CO2 continues to increase.
A. never
B. 100 - 150
C. 30 - 50
D. 50 - 100
C. 30 - 50
Name three ways that carbon dioxide gets into the atmosphere
Burning fossil fuels for
1. electricity
2. transportation
3. factories
Clearcutting to make room for an outlet mall.
Deforestation
Blood sugar increases and the pancreas releases insulin, liver removes glucose from blood and stores it as glycogen, blood sugar is set back to normal level.
This causes increased precipitation which results in flash flooding.
evaporation
Describe albedo effect.
Albedo is the amount of light and heat reflected. Ice and snow have high albedo and ocean and land have low albedo and result in more absorption of heat and light.
