Vocab
Any natural substance, organism or energy that living things use.
Natural Resource
Give 4 examples of a natural resource.
Answer Vary.
Looking for: air, water, soil, wind, oil, petroleum, coal...etc
The process by which wind and water transport soil and sediment from one location to another.
Erosion
A naturally formed inorganic solid with a crystalline structure
Mineral
____________ is a fancy word for mixture.
Aggregate
The process which used or discarded materials are treated for reuse.
Recycling
What makes something a Renewable Resource?
A natural resource that can be used and replaced over a relatively short time
DOUBLE POINTS!
The breakdown of rock into smaller and smaller pieces.
Weathering
Solid, geometric forms of minerals produced by a repeating pattern of atoms that is present throughout the mineral.
Crystals
_______________________ and _____________________ shape our planet.
Physical processes and human activities shape our planet.
The break down of rock into smaller pieces by physical means.
Mechanical Weathering
What is a Nonrenewable Resources ?
Natural resources that cannot be replaced.
What are the two different types of weathering? What is an example of each type?
here are two types of weathering: Mechanical weathering and chemical weathering. Mechanical weathering is when physical changes happen to rock. Wind for example can blow or move around rock often enough where a rough edge starts to become smooth. Chemical weathering is when the chemical makeup of the mineral changes. This happens when iron is left outside (in the air) for too long and turns into iron oxide; or when a fence starts to rust.
Four ways to identify a rock/mineral:
Color
Luster
Streak
Cleavage and Fracture

Oxidation

Why cant nonrenewable be replaced?
Nonrenewable reasources can not be replaced because once the resource is used up, there is no more.
Describe the two ways that glaciers erode.
Glaciers erode land by plucking and abrasion. Plucking occurs when a glacier moves over a fractured rock surfaces and loosens and picks up large pieces of rock. Abrasion occurs when a glacier and its load of rock pieces move along and grinds away at the surfaces of earth.
Why doesn’t it go in a specific order?
The rock cycle has three different stages as opposed to three different steps because rocks can be located where ever. They aren’t like a butterfly, for example where it goes through different life stages. Rocks all have different location on Earth. Wind, water, human factors and other parts of erosion can factor in to where the rock goes next.
Short Answer:
How does ice expansion affect the of our roads?
Answers Vary
The chemical breakdown of rocks and minerals into new substances.
Chemical Weathering
What should we do to help prevent the extinction of nonrenewable resources?
Answers vary.
Looking for:
-recycling
-using other sources of energy
-using less
Is it possible to stop erosion?
Why not?
We are not able to stop erosion, it is something that happens gradually and over time. This is because the Earth is always moving.
Why is "color" not the best way to identify a rock/mineral?
Mineral comes in many different colors, because of that it is not a reliable indicator of a mineral’s identity.
