If the cost of separating a mineral from waste rock becomes too great, the mineral may no longer be classified as an ore. This happens because ____.
A. The mineral can no longer be mined at a profit
B. The mineral has lost its usefulness
C. The demand for the mineral has decreased
D. None of the above
A. The mineral can no longer be mined at a profit
_____________________ scale is used to classify an earthquake based on a description found in ancient
writings.
A. Modified Intensity Scale
B. Moment Magnitude Scale
C. Richter Magnitude Scale
D. Seismic Magnitude Scale
A. Modified Intensity Scale
_______________________ are NOT changed to sediments by weathering and erosion.
A. Igneous rocks
B. Magma
C. Metamorphic rocks
D. Sedimentary rocks
B. Magma
_______________ are deposits of minerals large enough to be mined for a profit.
A. Metals
B. Sediments
C. Ores
D. Run-offs
C. Ores
__________________ is the amount of pore space in a material.
A. Deposition
B. Permeability
C. Porosity
D. Subduction
Porosity
Suppose digital technology, gold jewelry, and paper money caused the need for silver to no longer exist. Would silver still be considered an ore?
Silver would no longer be considered an ore. By definition, an ore is a mineral that contains a substance that can be mined for profit. Since silver would no longer be necessary, mining it would not produce profit thus causing it to no longer be considered an ore.
_______________ scale is used to measure earthquake intensity based on its effects on people and structures.
A. Mercalli Intensity Scale
B. Moment Magnitude Scale
C. Richter Magnitude Scale
D. Seismic Magnitude Scale
A. Mercalli Intensity Scale
Igneous rocks form from ____ when it cools.
A. Magma
B. Lava
C. Both magma and lava
D. Neither magma nor lava
C. Both magma and lava
______________ is a natural resource because it is used by living things to meet their needs.
A. Glass
B. Plastic
C. Land
D. Steel
Land
A low volume of pores means the rock has _____________ porosity.
A. High
B. Low
C. Medium
D. No
B. Low
How does the cost of removing waste material affect the classification of an ore?
If the cost of removing the waste material becomes higher than the value of the ore itself, the mineral will no longer be classified as an ore. It would no longer be economical to mine the ore.
____________________ scale is used to measure the energy or magnitude of the largest seismic waves
produced by an earthquake.
A. Mercalli Intensity Scale
B. Moment Magnitude Scale
C. Richter Magnitude Scale
D. Seismic Magnitude Scale
C. Richter Magnitude Scale
The rock cycle can change the sedimentary rock limestone into _____ through metamorphosis.
A. Conglomerate
B. Gneiss
C. Granite
D. Marble
D. Marble
Which of the following is a renewable resource?
A. Geothermal
B. Minerals
C. Natural gas
D. Oil
A. Geothermal
A(n) ____ is a layer of permeable rock that lets water move freely.
A. Aquifer
B. Cave
C. Spring
D. Water table
Aquifer
What three factors should be considered before mining a newly found mineral deposit?
1. the cost of mining the mineral
2. the demand for the mineral
3. environmental impact of the mine
____________________ is an area of many fractured pieces of crust along a large fault.
A. Crust zone
B. Fault zone
C. Rift zone
D. Soft zone
B. Fault zone
Which statement is correct regarding metamorphic rock formation?
A. Small pieces of rocks are buried, squeezed, and cemented together
B. The temperature inside Earth is cooler which allows metamorphic rocks to form quickly
C. The deeper into Earth’s crust, the higher the pressure that forms metamorphic rocks
D. Weathering and erosion cause rocks to break down to form metamorphic rocks
C. The deeper into Earth’s crust, the higher the pressure that forms metamorphic rocks
Which of the following is NOT a non-renewable energy resource?
A. Air
B. Coal
C. Minerals
D. Natural gas
Air
Which of the following determined the type of fossil fuel formed from prehistoric organic
matter?
A. Length and time the organic matter was buried
B. Temperature and pressure
C. Type of organic matter
D. All of the above
D. All of the above
Your friend states that she doesn’t understand what the big deal is about conserving fossil fuels. What are two reasons why conserving fossils fuels is important that you could share with your friend?
conserving fossil fuels is important because fossil fuels are a non-renewable resource. In other words, there is a limited supply. I would also tell my friend that conserving fossil fuels limits the damaging impacts of their use, such as air pollution.
Name three factors that decide the strength of earthquake.
1. Distance from Epicenter
2. Type of Rock/ Soil
3. Magnitude of Earthquake
What causes the difference in grain size between intrusive igneous rocks and extrusive igneous rocks?
When rocks cool slowly, as do intrusive igneous rocks, they have time to form large crystals, unlike rocks that cool quickly, which tend to form small crystals.
