In all cases PRINT the information on this assignment in a dark or visible colour.

Part 1.

Step One: On an 8.5 X 11 inch piece of typing paper. Draw a long rectangle about four inches wide and 7 inches long.

Step Two: This rectangle will represent a column of the atmosphere...that is ...a cross sectional model of the atmosphere.

Step Three: Going from the Earth's surface upward, Colour the layers of the atmosphere. Use solid colours for main layers and light blending colours to show the transitional "pause" zones. P

Step Four: Along the right side of the column write in the altitudes of the layers and the transition zones. Along the left side of the column write in the densities.

Step Five: Within the column show a line corresponding to temperature and associate this line with corresponding temperature values across the bottom of the chart.

Step Six: Add any cultural or physical attributes to your column that might enhance an understanding of the column and the atmosphere.

Part 2

On a separate piece of paper draw a sectioned diagram of either Washington or Oregon.This diagram can be an oblique view of these land features or a cross section.Identify the following physiographic features and label them:
In Washington, the Willapa Hills, the Puget sound Lowlands, The Olympic Mountains, The Cascade Mountains, The Rocky Mountains, The Columbia Plateau, the Pacific Ocean.
In Oregon: the Willamette Valley, The Coastal Mountains, the Cascade Mountains, The Columbia Plateau, The Columbia Gorge, The Blue Mountains, The Pacific Ocean, Klamath Mountains, The Great Basin.

It is winter. A parcel of air originates over the Pacific and encounters a Parcel of Air to the east of the Cascades which originates in Central Canada. Identify these air masses and label them with the correct air mass abbreviations. Show a key at the bottom of your diagram identifying what these abbreviations mean..

Next show the direction of travel of these air masses from which they are originating. Show a line where these two bubbles of air collide...they will collide in this model just east of the Cascade Mountains.

Identify the Leeward and Windward side of all orographic barriers. Show wet and dry (precipitation) zones using solid colours, and blend the traditional zones with lighter colours. Use a key to identify the colours with a precipitation zone. Label the rain shadows.

Staple these two sheets together with one Cover sheet. Make sure you name is in small letter on each sheet in the upper right hand corner of the work...just in case the cover sheet gets lost.

In both parts, be creative but substantive, add appropriate information. Sloppy work...or work scribbled out that produces a perception by the reader that care was not a part of the originators plan in developing the assignment.....will be graded down.
