What are three ways we use natural resources?
production of goods
What are some examples of natural resources?
oil, coal, natural gas, metals, stone and sand
air, sunlight, soil and water.
animals, birds, fish and plants
What is an inexhaustible resource?
A resource that can be used more than once and cannot be used up.
What is a renewable resource?
A resource that can be replenished at about the same rate at which they are used.
What are four examples of renewable resources?
What is a nonrenewable resource?
A natural resource is depleted more quickly than it can be regenerated. Once it is gone it is gone for more than 100 years.
Give two examples of nonrenewable resources.
fossil fuels
List three types of fossil fuels.
oil (petroleum)
natural gas (methane)
What is a fossil fuel?
A fuel (as coal, oil, or natural gas) formed in the earth from plant or animal remains. It takes millions of years.
List 3 inexhaustible resources.
What three human actions often lead to environmental problems?
natural resources
What is the benefit of greenhouse gases?
They absorb and retain heat from the sun.
What are three possible negative results of an increase in the global climate?
May cause flooding, drought, and disease.
What is water pollution?
the contamination of streams, lakes, underground water, bays, or oceans by substances harmful to living things.
How serious can the affects of water pollution?
It can kill plants and animals, or cause serious diseases such as cancer and even birth defects.
How can land pollution affect living things?
Contaminants from land pollution can be consumed by plants and animal, then consumer feeds on either the plant or the animal.
What are fertilizes used for?
to maximize the production of foodstuffs.
What are pesticides and insecticides used for?
to kill and deter weeds, fungi, and rodents and other pests.
How can pesticides and insecticides harm us?
Plants grow absorbing them and then when we eat the plants and sometimes they are carried in the air and we inhale them.
How can pesticides and insecticides get into our drinking water?
Through washed away topsoil that contains the chemicals that eventually reach a water source.
What are two ways landfills pollute in addition to being unsightly?
Contaminates filter though and get to groundwater and when trash is incinerated (burned) it produces air pollution
What are four heavy metals that often cause pollution?
copper, lead, mercury and selenium
What are possible sources of heavy metal contaminants?
industrial waste, car exhaust, mines and soil.
What would classify a substance as being hazardous?
poisonous, produce explosive gas, produces toxic gas
capable of corroding steel, or is
What is the danger of oil tankers and offshore drilling?
Most petroleum is poisonous and sometimes accidents occur that lead to oil spills killing many animals and polluting water.
What resources can be saved when we recycle glass?
sand, feldspar, limestone and soda ash plus all the energy used to obtain the resources.
What resources can be saved when we recycle aluminum?
95 percent of the energy required to make the same amount of aluminum from bauxite ore.
What steps can we make to reduce our consumption?
reducing what we buy,buying products with less packaging,reusing what we can and composting and recycling
What is biodiversity?
the variety of organisms that live on the Earth
If we no longer can get certain plants, how may that hurt us?
Many medicines will not be able to be made or maybe not even discovered.
How can destructions of ecosystems have a negative impact on our lives?
Loss of habitats may lead to extinction of different species.
What happens when oil tanks are routinely flushed out?
Add a lot of oil to the ocean. Oil is poisonous.
What makes a substance "hazardous"?
It is either poisonous, capable of producing explosive or toxic gas
capable of corroding steel, or
ist four heavy metals that are often contaminates.
copper, lead, mercury and selenium
How do heavy metals get into water sources?
industrial waste, car exhaust, mines and from soil.
What is a natural resource?
A naturally occurring materials such as coal, fertile land, etc, that can be used by man
What makes at substance plastic?
- Plastic is any man-made organic polymer. While plastics may be made from just about any organic polymer, most industrial plastic is made from petroleum.
Define mineral.
A natural substance of commercial value, such as iron ore, coal, or petroleum, that is obtained by mining, quarrying, or drilling.
Define coal.
- a black or dark-brown combustible mineral substance consisting of carbonized vegetable matter, used as a fuel. There are different types: anthracite, bituminous coal, lignite.
Define energy.
- the capacity of a body or system to do work.
Define fuel.
- combustible matter used to maintain fire, as coal, wood, oil, or gas, in order to create heat or power.
Define renewable resources.
- Resources that are replenished naturally in 100 years or less. Renewable resources are not always perfectly renewable.  If their levels are heavily decreased, they may not be able to completely replenish themselves.
Define photosynthesis.
- Photosynthesis is a process that converts carbon dioxide into organic compounds, specially sugars. It does this using the energy from the sun.
Define nonrenewable resources.
-  a natural resource that is present in limited supplies and depleted by use. It's basically a limited resource that we are extracting from the ground faster than it can replenish itself.
Define natural gas.
- a gaseous mixture consisting mainly of methane trapped below ground; used extensively as a fuel
Define conservation.
- the careful utilization of a natural resource in order to prevent depletion
Define inexhaustible resource.
- A resource that comes in an unlimited supply. It can be used over and over.
Define restore.
- to bring back to a former, original, or normal condition
Define impact.
- to have an impact or effect on; influence; alter
Define landfill.
- disposal of waste material by burying it under layers of earth
