100
This type of rock is formed when molten material, called magma cools and hardens.
What is Igneous Rock
100
Weathering is: * the movement of worn down rock * the settling of rock pieces in a new location * the breaking down of rock into smaller pieces
What is : the breaking down of rock into smaller pieces
100
Erosion is: * The movement of weathered rock * The breaking down of rock into smaller pieces * The settling of rock due to gravity, glaciers and water
What is : the movement of weathered rock
100
Which of these is a renewable resource? * coal * oil * water * natural gas
What is water (water is renewed in the water cycle)
100
What type of renewable resource would burning wood in your stove at home to heat your house.
What is biomass?
200
This type of rock is formed when when forces like wind, water and ice break rock into very small pieces to form sediment. Theses forces deposit the sediment into layers. The bottom layers become compressed and cemented to form rocks.
What are sedimentary rocks?
200
Which of the following is most likely to weather rocks on a mountain? * leaves decaying on the rocks * snow melting on the rocks * water freezing and melting in the cracks of the rocks * dew evaporating on the rocks
What is : water freezing and melting in the cracks of the rocks (this process slowly causes the rocks to crack more and break apart into smaller pieces)
200
Most canyons are the result of erosion caused by: * a volcano * a hurricane * a river * an earthquake
What is : a river
200
Fossil fusel are classified as non-renewable because they ... * can be easily recycled * come from deep within the Earth * will never run out * take a long period of time to form
What is : take a long period of time to form (fossil fuels take millions of years to form from the remains of once living plants and animals)
200
Types of renewable resource that produces electricity by running flowing water past a turbine.
What is hydroelectric power?
300
These rocks form when extreme pressure and heat change existing rocks into new types of rocks. The rocks do not melt. Instead their composition and structure change.
What are metamorphic rocks?
300
When water, wind, or ice moves sediment from one place to another it is called: * percolation * deposition * erosion * weathering
What is erosion
300
There is a heavy rainstorm on a farm. Which is most likely to wash away following the rain: * the gravel on the driveway * soil piled up on the side of the house * stepping stones in the garden * soil under the grass lawn
What is : soil piled up....
300
Which of the following is NOT a renewable resource? * plants * air * coal * animals
What is : coal (coal is a fossil fuel and takes millions of years to form deep underground)
300
This type of renewable resource uses energy from the Earth's interior.
What is geothermal energy?
400
This is a naturally occurring solid composed of minerals and sometimes other materials such as organic matter.
What is a Rock?
400
The type of weathering that breaks down rock without changing the composition of the rock.
What is physical weathering?
400
This process is the laying down or settling of eroded material.
What is deposition?
400
Earth's supply of oil is running out. Which of the following could produce more oil? * Metals bubbling up from below the surface * rocks melting below the surface * plant and animal remains becoming buried for millions of years * water dissolving underground minerals
What is : plant and animal remains......
400
Materials and substances found in nature and used by people for a variety of reasons are called:
What are natural resources
500
This material is formed rocks broken down by weathering.
What is sediment?
500
This type of weathering changes the chemical composition of the rocks.
What is chemical weathering?
500
Following a heavy rain, soil at the top of a hill is carried as mud to the base of the hill. What processes are involved in the movement and piling up of the mud? * weathering and deposition * weathering and erosion * erosion and deposition * evaporation and condensation
What is erosion and deposition (erosion is the movement of the soil by the water and deposition is the relocating of the soil/mud from its previous location)
500
What will most likely happen in the future if people continue to use fossil fuels at the same rate as today? * People will discover how to renew fossil fuels * People will need to create more fossil fuels * Fossil fuels will gradually disappear * People will have more fossil fuels in the future
What is : fossil fuels will gradually disappear
500
What happens to the bottom layers of sedimentary rock eventually after it has been deposited.
What is cementation and comaction?
