What is the cross section of a mountain?
A cross-section shows the shape of a feature (such as a mountain) viewed from the side, as if cut through with a knife. Cross-sections are constructed using the contour lines on a topographic map. (You may like to refresh your memory about topographic maps by reading the information box on page 2 of this worksheet.)
How do you draw a cross section of a mountain?
There are four steps when drawing a cross-section.
- Put a strip of paper along the cross-section and make a mark on your paper wherever the contour lines intersect with your paper.
- Take that strip of paper and put it on a clean piece of paper.
- Draw dots on the elevation lines defined by your strip of paper.
What is cross section in geology?
A geological cross-section is a graphic representation of the intersection of the geological bodies in the subsurface with a vertical plane of a certain orientation. It is an approximate model of the real distribution of the rocks in depth, consistent with the information available on the surface and the subsurface.
How do you draw a cross section of a building?
Steps to Drawing a Cross Section
- Draw the House Envelope. Start by drawing the width of the outer envelope of your house design through a given cross section line.
- Draw Floors and Ceilings.
- Side Wall Windows, Doors and Framing.
- Interior Walls and Structural Elements.
- Facing Wall Windows and Doors.
- Labeling.
What does cross section mean in math?
In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections.
Can the cross section of a solid ever be a point?
A cross section is the face you obtain by making a “slice” through a solid object. A cross section is two-dimensional. When a plane intersects a solid figure, the cross sectional face may be a point, a line segment, or a two-dimensional shape such as, but not limited to, a circle, rectangle, oval, or hexagon.
How do you scale a cross section?
It is typical to increase the vertical scale ratio by an order of magnitude compared to that of the horizontal scale. So if the horizontal scale is 1 inch equals 100 feet, a typical vertical scale for the geologic cross section would be 1 inch equals 10 feet.
What is cross section and block diagram?
A cross section shows the surface of the earth (with or without topography or elevation) and a vertical slice of the earth. A block diagram shows the surface of the earth and also at least one cross section. It is like a block or chunk cut out of the earth.
