What is cross in geography?

Cross sections are line graphs that show a sideways view of a landscape. They can show features such as hills and valleys, or depths, such as the depth of a river. Cross sections of hills use contour lines to determine the height of the land.

Accordingly, how do you draw a cross profile in geography?

Lesson Summary

1. Put a strip of paper along the cross-section and make a mark on your paper wherever the contour lines intersect with your paper.
2. Take that strip of paper and put it on a clean piece of paper.
3. Draw dots on the elevation lines defined by your strip of paper.
4. Draw a smooth line connecting the dots.

Likewise, what is a cross section? A cross section is the shape we get when cutting straight through an object. The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it. This is a cross-section of a piece of celery.

Also asked, what is a cross section of a conductor?

A cross section is the two-dimensional area you would get by cutting through the a conductor with a plane. For eg., a cylindrical conductor, if cut the normal way, has a circular cross section.

What is a cross section map?

Cross sections are line graphs that show a sideways view of a landscape. Cross sections of hills use contour lines to determine the height of the land. Cross sections of river depths are drawn using negative numbers so that the line graph looks like depth, rather than height.

How do you calculate a cross section?

Cross-Sectional Area of a Rectangular Solid

The volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h. Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.

How do you create a cross section?

2. Double-click an existing view.
3. Click Sections.
4. Click 2D cross-section.
5. Select Create New from the Name list in the Sections page.
6. Define the cross section as either Planar or Offset.

How do I create a profile map?

Draw a horizontal line on the graph paper that is the length of your profile line. Draw vertical lines above your starting and ending points. Label the y-axis (vertical lines) with elevations making sure that your scale goes from highest to lowest on your cross-section (see step 3).

Can contour lines cross?

Contour lines can never cross one another. Each line represents a separate elevation, and you can't have two different elevations at the same point.

How do you find area in geography?

CALCULATING AREA ON A MAP

1. Measure length in cm and convert to m / km.
2. Measure width in cm and convert to m / km.
3. Apply formula – L x W.
4. Write the answer in km² / m².

What is a map profile?

A survey strip map displaying the elevation of a road or planned road over the course of its route.

What is a cross profile?

A cross profile shows a cross-section of a river's channel and valley at a certain point along the river's course. Cross profile of a river. Near the source of a river there is more vertical erosion as the river flows downhill, using its energy to overcome friction (A).

How do you create a cross section in Excel?

Create a new row in the table and in cell B4 paste the formular =(C3+B3)/2. Then copy this into all the cells in the trapeziod row. This should calculate the values for this row for you. It is possible to use Excel to draw the cross-section and calculate the area rather than drawing it by hand on graph paper.

How do you find the volume of a cross section of a square?

Steps for Finding the Volume of a Solid with a Known Cross Section

1. Sketch the base of the solid and a typical cross section.
2. Express the area of the cross section A(x) as a function of x.
3. Determine the limits of integration.
4. Evaluate the definite integral V=b∫aA(x)dx.

How do you create a cross section in Autocad?

2. Click Layout tab Create View panel Section drop-down Full.
3. Click the view you want to use as the parent view.
4. Click in the drawing area to indicate the start point of the section line.
5. Click in the drawing area to indicate the end point of the section line.

Why are cross sections exaggerated?

Vertical exaggeration (VE) is a scale that is used in raised-relief maps, plans and technical drawings (cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.

How do you find the vertical exaggeration of a cross section?

To determine the amount of vertical exaggeration used to construct a profile, simply divide the real-world units on the horizontal axis by the real-world units on the vertical axis. If the vertical scale is one 1"=1000' and the horizontal scale is 1"=2000', the vertical exaggeration is 2x (2000'/1000').

What is area of cross section in electricity?

The cross-sectional area of a wire is directly proportional to the square of its radius (A = πr²), and hence to the diameter of the wire as well. Therefore, if we increase the diameter of the wire two times, its cross-sectional area will increase four times.

What is reaction cross section?

Cross section, in nuclear or subatomic particle physics, probability that a given atomic nucleus or subatomic particle will exhibit a specific reaction (for example, absorption, scattering, or fission) in relation to a particular species of incident particle.

What's the cross sectional area in square inches for a 10 THW conductor?

Question: Question 7 5 Pts What's The Cross-sectional Area In Square Inches For A 10 THW Conductor? O 0.0172 Sq In.

How does cross sectional area affect resistance?

More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.

Is diameter the same as cross sectional area?

Cross section is an area. Diameter is a linear measure. That cannot be the same. The cross section or the cross sectional area is the area of such a cut.

When the area of cross section of a conductor is doubled?

Also the resistance of a conductor is inversely proportional to its cross-sectional area (A) as R ∝ 1/A. Thus doubling its cross-sectional area would halve its resistance, while halving its cross-sectional area would double its resistance.

What is nominal area of conductor?

The nominal (see below) cross-sectional area for standard conductors including the following: Class 5&6: Maximum diameter of any component strand of the conductor.

What is conductor size?

In the United States, smaller conductors are measured using the American Wire Gauge (AWG). With the gauge system, the higher the number is, the smaller the cable will be. For larger wires, circular mils are used. MCM sizes, also called kcmils (kilo-circular mils), are for even larger cables. A 1000 (4/0) wire, has a .
