Natural Resources
Any material that is used by people!
List at least 3 physical properties of a mineral.
Color, streak, luster, hardness, fracture, cleavage, and density.
What process in the rock cycle changes igneous rock into sedimentary rock?
Weathering
What is the first step in the soil formation process?
The breaking down of already existing rock by weathering.
With the amount of carbon dioxide released from burning fossil fuels...How is this going to most likely affect Earth's climate?
Global Warming
What is a nonrenewable resource?
A nonrenewable resource forms at a rate that is much slower than the rate at which the resource is used.
List at least two characteristics of a mineral.
Possible answers could include: A natural, usually inorganic solid, definite crystalline stricture and chemical composition.
What type of condition changes the rock deep below the earth's surface?
High pressure
Which soil horizon can you most likely find humus?
A Horizon
What is one advantage and one disadvantage of hydroelectric energy?
An advantage is that as long as we have flowing water, we can have hydro-power. A disadvantage is that building dams can affect the organisms in rivers.
How might we use logs or already cut down trees as a material resource?
We can turn it into paper!
What are three ways that minerals can form?
Minerals can form from magma and lava cooling, metamorphism or from solutions.
If there is an area where deep cracks form and tectonic plates begin to move apart... What is this called?
Rift Zone
What is humus?
What is nuclear energy produced from?
Uranium Ore
Why are rocks, minerals, fossil fuels and soil important material and energy resources?
We need minerals, rocks, and fossil fuels to make everyday products, to construct buildings and roads and to provide energy.
To find the density of a mineral you must take the mass/volume. (grams/mL)
An unknown mineral has a mass of 64 g and a volume of 8 mL. What is the density of the mineral?
8 g/mL
How are metamorphic rocks formed?
From already existing rock going through heat and pressure and their molecules are then rearranged.
If I have a soil sample that is very smooth...What is it mostly made of?
Clay
What is an example of a renewable energy resource? What is one advantage and one disadvantage of this resource?
Possible answer could include: Wind energy. Wind energy will not pollute the air. Although, not everywhere on Earth is very windy.
Why is it absolutely crucial that we try to conserve nonrenewable resources?
We rely heavily on nonrenewable resources to meet a lot of our daily needs.
What is a silicate mineral? If you were to draw a picture, how would the atoms be arranged?
A silicate mineral contains silicon and oxygen and have orderly arranged atoms.
How might a sedimentary rock form, break down, and become a sedimentary rock again in another location?
They form when rock is broken down into smaller pieces by weathering (possibly from water or wind). The rock is then eroded (again by wind or water) and could be transported to another location. Finally, the sediment will be deposited and packed/layered over time becoming a sedimentary rock again.
If I have a soil sample that is very coarse and rough to the touch...What is is mostly made of?
Sand
What is an example of a nonrenewable energy resource? What is one advantage and one disadvantage of this resource?
Nuclear energy. It does not cause air pollution when burned, but it produces dangerous radioactive waste.
