Resources
Give me an example of a nonrenewable resource?
coal, oil, gas, etc
What does the term "carbon footprint" refer to?
The total greenhouse gases produced by human activities
Which layer of soil contains Organic Matter? Where is it located and what is the Horizon Letter?
The very top later, Horizon O
What is Species Diversity?
Number of different kinds of species in an ecosystem
Difference between wetlands and estuaries?
Estuaries form where freshwater meets saltwater, wetlands may contain either as it is anywhere the waterline is above the soil
Give me an example of a renewable resouce
Solar, Wind, Hydro, etc
Major cause of water pollution in communities
Stormwater Runoff that carries trash and pollutants to nearby streams and water basins
What are some factors that may increase soil erosion? (give me two)
- Increased Slope
- No vegetation
- Heavy Rain
What is one impact of human consumption/expansion on biodiversity?
Habitat Loss, Extinction
What is Conservation
To protect and manage resources for the future
Give me one of the biggest challenges with shifting to renewable resources
Money, space, time, available resources
What is the difference between Point Source and Non Point Source Pollution? Which is easier to clean up?
Point Source- can locate the exact cause of the issue and easily fix it (chemicals from a factory)
Non Point Source- comes from a more general location and is harder to clean up (runoff)
What materials make up soil?
Weathered rock and organic material
What is Biodiversity?
The variety of life at all different levels
Give me the vocab word that matches this definition:
Using resources in a way that does not harm the ability of future generations to meet their needs
Sustainability
Why is resource overuse becoming an issue?
What is a result of resource overuse?
Population growth increases the demand for resources
Leads to resource depletion (run out of resources)
Which is a consequence of excessive fossil fuel use?
Increased greenhouse gases, Climate Change/Warming, etc
What is the difference between...
Sheet Erosion
Gully Erosion
Rill Erosion
Sheet: Removal of soil in thin, even layers across land
Rill: Small channels formed by running water that can be smoothed out
Gully: Large channels that cannot be easily fixed by normal farming
What is Ecosystem Diversity?
Give me an example of two different ecosystems
Variety of ecosystems
Examples: tundra, dessert, grassland, forest, etc
What is Ecosystem Resilience?
Recovery while maintaining structure and function
List two different resources that need to be extracted. How are they extracted?
Minerals, rock, sand- Mining
Oil, gas- Drilling
Wood- deforestation
Water- pumped from aquifers, wells, other sources
List all five of the Greenhouse Gases we talked about in class.
Carbon Dioxide, Water Vapor, Ozone, Nitrous Oxide, Methane
List the layers of soil in order from top to bottom. Include both the Horizon letter and Soil Name
O- Organic Layer
A- Topsoil
B- Subsoil
C- Parent Material
R- Bedrock
Why is Genetic Diversity Important? How does it make species more resilient?
Helps species adapt to environmental changes
What is Succession?
What is the difference between primary and secondary succession?
Succession: Recovery after a disturbance
Primary- start from nothing but bare rock
Secondary- start from something, like soil or seeds
