The layers of rock (strata) we see on the Earth's surface are rarely found in their original flat orientation. Measuring dip and strike is pretty easy, all you need is a compass for the level direction, and a clinometer to measure the vertical angle. For basic dip measurements I use an angle finder from a hardware store costing a couple of pounds (about 3-4 dollars US). I expect your tutor will expect you to sing the praises of the expensive "Brunton" combined compass and clinometer. (I don't know why, I have never found the point of spending huge amounts of money on this - but they remain a venerated item min American geology)
Why bother? Measuring dip and strike is a fundamental part of geological mapping as you can build up a picture of the tilting and folding of the rocks beneath the surface, and start to build up a three dimensional model of the geology from the two-dimensional information at the surface. This is useful in predicting such things as the location and depth of an underground coal seam, or of working out the geological history of an area.
If you cannot measure dip and strike directly, by measuring it off the surface of an exposed outcrop, then you can calculate it by measuring the height and direction an outcrop of the same strata run on opposite sides of a hill or valley, and doing some trigonometry.
The magnetic field can certainly be detected by a compass.The 'lines' are a handy human invention, and don't really exist, so you could not,say, trace out the lines with a compass, because they're not there.But place a compass next to a wire that's involved in any battery-operated (DC)circuit, and the compass absolutely goes crazy !
A medial direction using a compass refers to navigating straight ahead to maintain the current direction without veering to the left or right. It involves walking in a straight line relative to a compass reading, typically without any deviations.
guess an check.
No, a compass is a navigational instrument that helps determine direction. A compass rose, on the other hand, is a figure on a map or nautical chart that displays the orientation of the cardinal directions (north, south, east, west) and intermediate directions.
The poles of a button magnet can be determined by using a compass. Place the compass near the magnet and observe which end of the compass needle points towards the magnet. The end pointing towards the magnet's north pole indicates the south pole of the magnet, and vice versa.
these are the ancient ways: using pi using a ruler using the side of your hands to measure compass
To measure 310 degrees, use a protractor or a compass. Start by marking a baseline; from the baseline, measure 310 degrees clockwise. If using a protractor, align the center point with the baseline and mark the 310-degree point, then draw a line from the center to this mark. If using a compass, rotate it 310 degrees from a reference direction and mark the point on your surface.
To draw a decagon using a compass, start by drawing a circle with the compass. Mark the center of the circle and label it as point O. Then, divide the circle into ten equal arcs by first finding the radius and using a protractor to measure 36-degree angles (360°/10). Finally, use the compass to mark each point around the circle, and connect these points to form the decagon.
It is indeed impossible to trisect an angle using only a [pair of] compass[es] and a straight edge.It is in fact possible:1) measure the angle2) divide this measure by three3) measure the angle found in part (2) inward from the outer edge of the main angle4) use the straight edge to draw the trisectorsit is!!!!!!!!!!!!!!!!!!

When you are using a compass you are navigating to a certain point. So it could be navigation.
You can use a protractor! Draw the baseline and measure the angles and mark them. Then finally join them together!
by looking at the compass the wrong way or maybe using it wrong
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.
If you have a protractor: Draw a line from the center of the circle to the outside (radius), then measure 60 degrees and draw another line. If you have a compass: Draw a circle using the compass, then, using your compass, place the compass needle on the edge of the circle, draw another circle (KEEP THE RADIUS THE SAME). Your two circles should have two intersection points. Place the needle on one of the intersection points and repeat the process. I suggest you look at:
An angle of 65° can not be trisected using a compass and straight edge.
It is not known what exact tools Tycho Brahe used to measure the planets and stars movements. He may have made special calculations by using some type of compass.
