Isopach maps are where you are contouring the With contaminant plumes the z parameter is the concentration of Of gravity, or the strength of a magnetic field. You can contour geophysical parameters such as the acceleration In this case the z axis instead of beingĮlevation can be any physical/chemical parameter. You can also contour and 'map' other features For example the surface created by the top

Your surface does not have to be continuous everywhere,īut can be truncated. There are some differences between standard topographic As we will see in later labs one can also map the density of point data. However, one can get much more sophisticated and contour for example the amount of offset on a fault surface (which shows a very interesting pattern). Geologic surfaces commonly mapped in this way are: Structure contour maps are basically the sameĪs topographic maps, where the surface being mapped is some geologic The strcture is basically that of an asymmetric syncline with a steeper SW limb. be able to interpret the structure contoursĮxample of a structure contour map from the USGS.be able to use Surfer (or equivalent software).construct map pattern of a contact from structure.Local strike and dip) from structure contours. be able to calculate surface traits (e.g.know the definition of a structure contour.Finished pieces can be mounted on a piece of black construction paper with glue sticks, or staples.Suggest bright colors to create a cartoon or Andy Warhol-like effect. After creating the line drawing, use the oil pastels to color in the face in an unusual way.Retrace the pencil line with a black Sharpie.Remember to add glasses, earrings, and anything else unique to their own face.Suggest that they start from one side of the face, or the top or bottom, and continue around the entire face including the eyes, nose, and mouth.Students should hold their mirrors or set them flat on the table and look only at their image while they draw their face without lifting the pencil off the paper.When the students are finished, they can take a piece of watercolor paper, two pieces of masking tape, and a mirror from the front table.Remind them to draw in their knuckles, rings, etc. Guided Practice: Have the students hold up their hand, take their pencil in the other and have them look only at their hand while they draw what it looks like, without looking at the paper or lifting their pencil off the page.Notice how the wire starts at the chin and continuously winds around the shape of the face including the ears to the bottom of the chin. The artist, Alexander Calder, created Contour Line drawings of faces and circus animals using pen and paper and also wire.They are created by looking only at the subject and not the paper while drawing.Blind Contour Drawings are created with one line never picking the pencil up off the page.Straight lines look flat but curved lines give more dimension. Contour Lines can make an object look 3-D as on the following slide of the Contour Map.(Follow slides below – all slides are in the power point)

Today we’ll discuss Contour Lines and how they can make art work look more interesting and realistic.

“A line is a dot, that went for a walk” from Paul Klee. Explain how Line is the most basic element of drawing, basically a moving dot.

Ask students examples of Line in art they know: prompt cartoons, stick drawings, etc.

Save the watercolor paper and mirrors – give to the students after they have practiced drawing.

Students can share oil pastels placed in small bowls set at the tables.

Tape down the practice paper on the tables.

Each student will receive a piece of white construction paper (to be used for drawing practice), a mirror, a pencil, and a sharpie.

White construction paper cut into half sheets.
