Models and Systems

How might meteorologists use models to help the general public?

• They show us what happened in the past

• They let us know what the weather will be like in the future

• They teach us how to read the models

• They show us how to read the colors on the models

How might Scientists' ability to forecast weather events, such as storms, be affected if they were unable to create models of those systems?

• They would not have a job anymore

• It would not affect it at all

• They might not be able to prepare us for big storms

• They would have to do it all by hand

The product of a system

• Component

• Input

• Output

• Feedback

A boundary, as we have been studying it, is known as

• the edges of NC

• edges of a system and identifies the components of a system

• all of the parts within a system

• the outside of the USA

How would re-grouping two systems affect the components and boundaries of the new, larger system?

• It would be a much smaller scaled system

• The system would have less components and processes

• This could never happen

• The system would have more components and processes

A snail feeds on algae that consume the carbon dioxide produced by the snails. Which sentence describes this ecosystem?

• The algae make up a natural system that does not have any output.

• The snail is a mechanical system and carbon dioxide is an output.

• The output of the snail's system is the input for the algae's system.
