natural resources
Something on Earth that living things use to meet their needs
natural resource
Name one way that minerals form
the process by which commercially valuable resources are removed from Earth
mining
a material obtained from a natural material that has undergone a chemical reaction in a lab or factory
synthetic material
very concentrated form of chemical energy that easily transforms into other forms of energy
fossil fuels
Permeability depends on what two factors?
porosity and connection between pores
How is coal extracted from the earth?
through mining (like minerals)
a secondary product that results from a manufacturing process or chemical reaction
by-product
True or false: nonrenewable resources never replenish.
If false, explain why the statement is false.
False - nonrenewable resources replenish, but they do it more slowly than they are used
What are the three factors that fossil fuel formation depends on?
type of organic material, temperature/pressure, time
How are natural gas and oil removed from the earth?
drilling
What is the relationship between natural and synthetic materials?
synthetic materials are made from natural materials
Give an example of a renewable and a nonrenewable resource
renewable: wind, solar, hydro
nonrenewable: fossil fuels, minerals
Where are the best groundwater basins found?
valleys with high porosity and permeability (made of sand/gravel)
groundwater is withdrawn from aquifers faster than natural recharge can replace it
groundwater overdraft
Natural materials are materials that are made from any of these 3 things:
plants, animals, ground
Give an example of how we use each of the following resources: land, air, and water
land: build, play, live on it
air: get oxygen to perform cellular functions
water: agriculture, drinking
Name the 5 factors that soil formation depend on
parent material, time, living things, climate, topography
What are 2 potential negative consequences of extracting fossil fuels?
Can disturb habitats, change landscapes, and pollute water by runoff that contains heavy metals from mines
Name one thing that synthetic material production depends on and explain how it affects production
natural resource availability - syn. materials depend on available resources (if you have iron, you'll make steel)
economic conditions - good conditions mean that technology can be for entertainment
society - desires/needs of people drive syn. production
