Mod 4 lesson 4 Flashcards
Biomass?
: organic matter that can be used as a fuel source
Nonrenewable resource?
: a natural resource that is in limited supply and/or takes more than a lifetime to replenish
Global effect?
: general practices carried out by many that affect a very large area and/or number of people
Local effect: the actions of a few individuals that affect a small area and/or a smaller number of people
Urbanization?
: the process of clearing natural vegetation and replacing it with concrete and buildings
Geothermal energy?
: renewable energy captured through using the heat of the Earth
Desertification?
: the process that causes fertile land to become desert-like
Renewable resource?
: a natural resource that is replaceable through a cycle in nature or sustainable practice in one lifetime
Fossil fuel?
: a nonrenewable fuel such as coal, oil, or gas created from the remains of living organisms
Recyclable
existing materials that can be re-purposed to make new products
Deforestation?
the permanent destruction and clearing of forests and plant life in an area
Examples of Renewable Resources?
Examples: sunlight, wind, water, trees/plants,
geothermal energy, biomass
Examples of Nonrenewable resources?
Examples: fossil fuels, glass, metals, rocks/minerals
Examples of recyclable material?
may include renewable and nonrenewable resources such as aluminum, plastic, cardboard, composted kitchen waste, glass, paper, and textiles.
What are some effects of Deforestation
Loss of important forests (rainforest)
Loss of animal, plant, and insect habitats
Decrease of oxygen production
Increase in carbon dioxide levels in the air
Increase in erosion
Increase in extinction
What are some Effects of Desertification?
Fertile land becomes desert-like
People and animals must move to find other areas to live
What are some effects of Urbanization?
Loss of animal, plant, and insect habitats
Increased pollution
Disruption in water flow
Increase in the spread of disease
What are some causes of Urbanization?
Clearing natural landscape and replacing with concrete and buildings
Many people living close together in a small area
What are some causes of Desertification?
Poor farming practices that deplete the soil of nutrients
Animals overgrazing, leaving the soil unprotected from erosion
What are some causes of Deforestation?
Cutting down trees for wood
Clearing forests by burning
What are some ways Humans impact the water supply on earth?
- Pesticides and fertilizers pollute our water and organisms living in it
- changing the water flow such as dams
- Construction, clearing forests, adding dirt, chemical runoff
- Shipping, adds pollution, disturbs marine life, invasive species
- Recreation, pollution, upsets balance of the nutrients in water, disturns marine life
How can Humans decrease their ecological footprint?
recycling, using fewer nonrenewable resources, conserving energy, composting, and planting trees
What is an example of a global effect?
Global food supply
What are some examples of local effects?
- Removing beach grass from the coastal areas, taking away natural filters
- Clearing trees to create roads increasing pollution
- Clearing trees to build power plants, increasing pollution, contamination surrounding environments
