Natural Resources
What is a material resource?
A natural resource that humans use to make objects or to consume as a food or drink.
Where can a majority of fresh water be found in
Icecaps and Glaciers
What is desertification
The process of land forming desert-like conditions
What are the three reasons as to why the atmosphere is important for human survival?
It provides gases needed to survive, it absorbs harmful radiation from the sun, and it keeps the Earth warm.
What is one material resource that could be obtained from plants?
Cloth, fruit, and crops as well as lumber, paper, and sap from trees.
Describe an aquifer.
A body of rock or sediment that can store water and allow water to pass through it
What is deforestation?
The removal of vegetation from an area.
List a natural and a human-made source of air pollution:
Natural sources: volcanoes, wildfires, and dust storms
Human sources: Burning fossil fuels, chemical manufacturing plants, dry-cleaning, auto repair shops
Where do we get most of our energy resources?
Through the drilling and burning of fossil fuels.
How does water supply influence where people live.
There must be enough water available to sustain a large population of people and to grow enough crops to feed them.
What are some recreational activities than affect land?
Creation of parks, vacation destinations, driving cars, etc
When are gases considered to be pollutants
How could water become a nonrenewable resource?
If we use water faster than it is replaced, it will be considered nonrenewable.
What is the difference between non-point source pollution and point-source pollution?
PS: pollution from one specific site
NPS: many small source of pollution.
How could deforestation lead to desertification
deforestation destroys vegetation in the area, including the roots that keep soil locked in place. Without plants, the soil erodes and become unlikely to sustain life.
How does acid rain/precipitation form?
Gases mix with water in the air to make it acidic. This then falls to the ground and may cause land to erode and a pH imbalance in waterways
Name a type of nonrenewable resource that also affects air quality?
Fossil fuels
How can we measure water quality?
By looking at:
- Dissolved solids
- Turbidity
- Dissolved oxygen
- Microbial load
- pH
What are some negative effects on land that come from urbanization?
Roads increase pollutants, areas that are highly population create more pollution from garbage, etc.
How do we measure air quality? What exactly is being measured?
We use an air quality index that measures the pollutants in the air such as ground-level ozone and particulates.
Where did Ms. Carr work before she began teaching and what did she do?
Florida Department of Environmental Protection
Wrote grants to improve water quality in the State of Florida
