What is a concept map?

Concept maps are learning tools used to relate concepts with each other.  Concepts (ovals) are linked to each other by a "linking statement".  This statement is meant to outline the relationship between the two concepts.  Try to develop a concept map for the following paragraph.

 

 

What Causes Waves?

The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves. You can make your own miniature waves by blowing across the surface of a pan of water.

Waves of water do not move horizontally, they only move up and down (a wave does not represent a flow of water). You can see a demonstration of this by watching a floating buoy bob up and down with a wave; it does not, however, move horizontally with the wave.

Tsunamis (sometimes called tidal waves) are different from surface waves; they are usually caused by underwater earthquakes, volcanic eruptions, or landslides.

Questions

1. What is the main concept of this passage? Waves

2. What secondary concepts are related to the main concept? wind, size of wave, wave motion, tsunamis

3. What relationships can be developed between the main and secondary concepts?

    wind- transfers energy to water through friction

    size of wave- larger waves are caused by stronger winds

    motion- waves move up & down not horizontally

    tsunamis- very large waves caused from earthquakes, volcanoes or landslides

4. Draw what you think a map should look like.
