T/F Wind, water, and planting trees all allow erosion to take place. A 100
False A 100
T/F Growing tree roots, rain, and freezing and thawing ice all cause physical weathering. A 200
True A 200
Which would chemically weather faster: marble gravel or quartz gravel? A 300
Marble gravel A 300
Are the particles that make up soil normally all the same size or different sizes? A 400
Different sizes A 400
What breaks large rock into smaller pieces? A 500
Physical Weathering A 500
Weathering of rocks into smaller particles is a very fast process. True/False B 100
False B 100
What is the difference between physical and chemical weathering? B 200
Rocks are physically weathered by breaking them into smaller pieces. Rocks are chemically weathered when compounds in the rock react chemically with another chemical and this weakens the rocks. B 200
Wind blowing over a field is a cause of chemical weathering? True/False B 300
False B 300
What are three components of soil? B 400
Gravel, sand, and organic material B 400
Erosion takes place when ________ B 500
Rocks and soil are transported from one place to another. B 500
The tool used to separate the soil to analyze the different components? C 100
Sieve C 100
Why are sieves used to analyze soil? ____________ C 200
They separate soil by particle size. C 200
What are mixtures of different elements and chemical compounds that combine in different proportions to form hard, solid materials of the earth’s surface? C 300
Rocks C 300
DAILY DOUBLE C 400 DAILY DOUBLE Place A Wager
What are the elements and compounds found in rocks? They are solid and possess a crystal structure. C 400
Minerals C 400
What is the mixture of organic component, sand and gravel that makes up the upper surface of the Earth? C 500
Soil C 500
Why would marble gravel weather faster than quartz gravel? D 100
The quartz will not react as fast as the marble when exposed to certain chemicals. D 100
What are some things that a person could do to reduce erosion. Name two and explain. D 200
Vegetation could be added. Vegetation decreases erosion by slowing the flow of water and by catching and preventing soil from flowing down the hill. Obstacles could also be added. These also slow down the water and catch the soil. D 200
What are two processes that contribute to forming and depositing soil? D 300
Weathering and erosion. D 300
Fragments of rock provide nutrients for living plants. True/False D 400
True D 400
Would plants releasing oxygen into the air speed up chemical weathering? Yes/ No D 500
Yes D 500
Would a large stone statue or marble gravel weather faster? E 100
Marble gravel E 100
A scientific tool used to measure mass. E 200
A triple beam balance E 200
A tool used to measure volume. E 300
A graduated cylinder or a beaker or a falcon tube. E 300
A scientific tool that is used to measure force in newtons is the _________ E 400
Spring scale E 400
A basic metric unit of measurement used to measure distance? E 500
meter E 500
The classification of Mammals with pouches F 100
What are Maruspials? F 100
This second largest bird in the world is native to Australia F 200
What is the ostrich? F 200
Australia’s wild dogs F 300
What are dingos? F 300
This Australian island is the home of a devil and a wolf F 400
What is Tasmania? F 400
Although the National Bird of New Zealand, it is also indigenous to Australia F 500
What is the Kiwi? F 500
The Final Jeopardy Category is: Physical and Chemical weathering Please record your wager. Click on screen to begin
How does physical and chemical weathering combine to weather rocks? Click on screen to continue
By breaking rocks into smaller pieces, physical weathering exposes more of a rock’s surface to chemical weathering. Chemical weathering softens and weakens rocks. The combination of the two speeds the overall process of weathering. Click on screen to continue
