Term
At what temperature do thing's not have enough energy to move?
Definition

Aboslute Zero

-273 C

Term

What was the Warmest year localy?

 

Definition

2012

52.1 F

Term
What was the average temperature in the united sates on 2012?
Definition

55.3 F

Warmest year since records began

Term

Describe:

 

Spacial Scale

Definition
Ex: If you judge warming by what you experience locally  the results might be biased
Term

What are the Results of El Nino?

El Nina?

 

Definition

Trade winds flowing west from south america are week; this means little cold water being brought up from the deep ocean;and this results in the ocean being warm 

 

Strong trade winds from South America, cooler ocean temp

Term
Temporal Pattern:
Definition
Change has different patterns that can make detection complex
Term
Directional
Definition
Small changes occur between observations but all in one direction
Term
Random Pattern
Definition
Samll or large changes occur between observations, and direction changes in a non-predictable manner
Term
Cyclic Pattern
Definition

Direction Changes from increasing to dcreasing to incresing

 

 

Term
Why is there a need for Earth System Sciences?
Definition
  1. Collect long tern records to assess the climate change that is random, cyclical and directional
  2. collect global records to detect climate changes
  3. build models to predict the changes in systems by changing one or more variable
Term
What are the Goals of Science?
Definition

Understand why things happen and predict what will hapen 

Science is to adress questions about our physical and social enviorment 

Science deals with things that can be observed or mesured

scientific questions are risen from social values

Term

What do Scientist do?

 

Definition
  1. creat models
  2. the best models is the one that explains the most observation of reality
  3. no model can contain all variables
  4. making all models incomplete 
Term

what are the steps in scientific study?

 

Definition
  1. Informal Question Ex: is it getting warmer?
  2. hypothesis is formed
  3. observe and mesure dependent and independent variables 
  4. create a model
  5. use model to predict dependent in diffferent conditions
  6. gather new observations to test model 
  7. attempt to verify model
  8. revise model
  9. make new predictions
  10. action: resolve the problem with the model
Term

What is the dependent and Independent variable?

 

 

Definition

Depended (the effect)

Independent ( what is causing it to happen)

 

Term

When is a model perfected?

 

Definition
models are never percected; there is always something unexpected that will influence the results
Term

When are models useful?

 

Definition
When error is lower than our needed accuracy
Term

We watched a video in class about what scientific experiment?

 

Definition
An egg drop and foam it was not a good model because it didnt use flex gel
