Gold and Pyrite have similar colors but are not the same mineral. What property of minerals could you use to tell the difference between the two?
Streak
100
What is the difference between renewable and nonrenewable resources?
Renewable resources are continually being replace and will not run out. Nonrenewable resources cannot be replaced quickly enough to keep from running out.
100
What are the causes of weathering?
wind, water, ice, and platns
100
What is erosion?
erosion is the moving of sediment and rock from one place to another
200
How are sedimentary rocks formed?
small pieces of rock and other materials settle on top of each other and become squeezed together
200
How do scientists measure hardness?
by how easily the mineral can be scratched
200
What are two types of resources available in Florida?
water, phosphate, oil, limestone, silicon, wind, or solar energy
200
What is the process of scraping materials away?
abrasion
200
The three most common types of erosion are:
wind, water, ice/glaciers
300
How are metamorphic rocks formed?
when existing rock is changed by heat or pressure
300
Which property is related to how a mineral's surface reflects light?
luster
300
What makes water a renewable resource?
Earth's supply never runs out
300
How does water weather rocks?
water carries pieces of sediment that rub against the rocks and weather them
300
How does wind erode the Earth's surface?
wind carries dust many miles away to different places and drops it there
400
Adrian found a rock that had layers. What kind of rock did he find?
Sedimentary
400
Which mineral is the hardest?
diamond
400
What are three examples of nonrenewable resources?
rocks, metals, fossil fuels, coal, andsoil
400
How do plants and ice weather rocks in the same way?
both expand/grow inside a crack
400
How are weathering and erosion different?
weathering causes rocks to break into small pieces, erosion carries these pieces away
500
What are the two things that can change a rock?
heat and pressure
500
List three properties of minerals other than color.
streak, hardness, luster, cleavage, magnetism, or reaction with acid
500
How can wind energy be used?
wind can be used to create electricity
500
What happens to rock as it weathers?
its size gets smaller; it breaks into smaller pieces
500
What is one example of erosion?
river carrying soil away from the bank
ocean waves carrying sand along the shore
wind carrying dust long distances
glaciers moving rocks over land
