Lists of things I know
|
Land becomes dried up due to lack of water resources
|
Being a resident of the southwestern states and living through a drought.
|
Life experience, witness to the effects of a lack of water resources.
|
|
Crops, vegetation, and living things die off due to a drought
|
Being a resident of the southwestern states and living through a drought.
|
Life experience, witness to the effects of plants dying off and animals perishing or migrating.
|
|
Debris engulfs the air
|
Being a resident of the southwestern states and living through a drought.
|
Life experience, witness to the effects of dust storms to a small degree.
|
|
Rising temperatures is a contributing factor to a drought
|
Being a resident of the southwestern states and living through a drought.
|
Rising temperatures lead to evaporation.
|
|
Overpopulation is a contributing factor to a drought
|
Logic: General population depending on the same natural resources
|
Natural resources are not growing as rapid as the population and are not replenishable.
|
|
Fracking is a contributing factor to the pollution of water resources
|
Contamination of water resources resulting in nonpotable. Documentary on fracking.
|
Chemicals are leaking into the soil and contaminated water resources
|
|
Less rain is a contributing factor to a dust bowl.
|
Life experience.
|
Shrinking water resources. Rivers, lakes, etc.
|
|
I know that debris in the air causes breathing problems. |
I have a cousin who has asthma. |
It is hard for him to play or be outside when it is windy because his breathing gets heavy. |
|
I know that if there is enough debris in the air to block out the light, biological processes will be hindered. |
I saw a movie once where they were racing horses, and there was a massive sandstorm that blocked out the whole day. It went completely dark. |
When there is a lot of particles or dust in the air, it is thick enough to block out rays from the sun. |
|
Vegetation is affected by a lack of water. |
Plants cannot grow without water and sun. |
In order for photosynthesis to ocur requires both water and sun. |
List of things I know I don’t know:
|
I know nothing about the Ogalalla Aquifier
|
Course reading discusses the depletion of this resource as a contributing factor to the dust bowl.
|
I don’t know enough about the Ogalalla Aquifier to determine the impact of this natural resource.
|
|
I don’t know all the contributing factors of the Dust Bowl in the 30’s
|
Economic factors, water resources and government acts are contributing factors according to the course readings.
|
I don’t know how these contributing factors play in if at all, and what other factors that are not mentioned may have contributed as well.
|
|
Economic factors are not discussed but seem to be a contributing factor.
|
The course readings do mention the Great Depression which coincides with the Dust Bowl
|
Economic factors need to be investigated as to how much this contributed to the Dust bowl.
|
|
|
|
|
List of things I wonder about
|
I wonder how much land was abandoned during the dust bowl.
|
Homesteaders were partly to blame for the dust bowl according to the class readings.
|
How much land actually abandoned by the homesteaders may determine how much it was a contributing factor.
|
|
I wonder if there might be alternative water sources.
|
There are different types of water recycling available.
|
I am not aware of all types available.
|
|
What measures are being taken and can be done to reduce our intake of water.
|
There are water conservation regulations that have been set locally.
|
What other water conservation methods can be implemented?
