Apes Cards #1 Flashcards
Mesosphere
Extends from 50-80 km above Earth.
Troposphere
The layer that contains the earth’s daily weather and most access to the sun.
Stratosphere
The earth’s ozone layer exists in this layer of the atmosphere.
Thermosphere
The highest layer of the atmosphere above 80 km.
E Horizon
Silt and sand are concentrated.
O horizon
Litter layer mostly undecayed materials.
Bedrock
The deep underlying non soil materials.
B Horizon
The layer where minerals that were leached out of the layers above accumulate.
A Horizon
A mixture of soil loam and detritus, the topsoil.
Aids
The virus that causes this disease is transmitted through bodily fluids.
Earthquake
Can cause massive destruction.
Asbestosis
Caused by microscopic fibers of a mineral.
Radon
Radiation that causes cancer.
Correct geological era’s in order
- Precambrian
- Paleozoic
- Mesozoic
- Cenozoic
Evolution
Changes in the genetic composition of a population over many generations.
Conservation easement
A binding agreement that preserves land from further development in exchange for tax write offs.
What can ozone in the troposphere cause?
Eye irritation, bronchitis, headache, emphysema.
What is a benefit of genetically modified food?
The improved yield in crops.
What is the percent of world’s solid waste produced by the US?
33%
Carrying capacity
The maximum number of a species that can be sustained in an ecosystem.
Bioaccumulation
The selective absorption and storage of a great variety of molecules.
Biomagnifcation
Occurs when the toxic burden of a large number of organisms at a lower level is accumulated and concentrated by a predator in a higher tropic level.
LD50
A chemical dose lethal to 50 percent of a test population.
Doubling time formula
70/ percent population growth.
Percentage population growth formula
70 divided by doubling time.
Ecological succession
The changes that take place in an ecosystem.
Primary succession
Starting from bare rock, slowly over time, soil is built up and then plants and animals colonize. Drastic disturbances like volcanic eruptions or major mudslides, as well as new island formations, can result in primary succession.
Secondary secession
- The process of nature reclaiming an ecosystem that used to exist but was disturbed.
- Disturbances like forest fires, deforestation, and hurricanes may remove most of the organisms in a system that used to exist but was disturbed is secondary succession.
Tragedy of the commons
1968 by Garret Hardin, the idea that there is a finite maximum number of people the earth can support and how we use earth’s resources is an important factor in determining how many people can be sustainably supported.
Tragedy of the commons
Commons: any resource used by several people but owned and controlled by no one.
Tragedy of the commons
The tragedy is that each person with access to the resource has no reason to limit his or her consumption of the resource.
Globalization
As people become more and more mobile, and nations depend more and more on each other, the world is becoming a single community.
Doubling time formula
70/ rate
