Nebula Supernova - Crab Nebula. The Crab Nebula represents a violent supernova explosion of a star (likely a third, fourth, or e

ven later generation star). Heavy elements with atomic weights greater than 26 (and some with lesser atomic weights between oxygen and iron) were likely generated during this explosion. Which element probably formed in a supernova?a. Gold (Au) b. Carbon (C) c. Hydrogen (H) d. Helium (He)

Answer:

a. Gold (Au)

Explanation:

  • The crab nebula consists of an oval-shaped mas of the filaments and they are imprints of the progenitor star that surrounds the diffused blue region and is helium-rich, other than gold other elements like the iron, oxygen and the uranium are produced.

1. A to B would be a much steeper slope than D to B.

Explanation:

The map that is presented has contour lines on it. This gives us a very nice representation about the relief, thus we can easily see where the slopes are steeper, and where they are less steep. While some parts are relatively flat or with less steep slopes, some are very steep, so much so that it would be very hard to move through those parts.

If we move from A to B, the starting point will be in a small strip of coastal lowland. This soon changes, as relatively steep parts come on the way. After that, the steepness is smaller, but gradually increases, and just in front the B point, the slope is extremely steep, so most probably a special equipment will be needed to go through it.

Between D and B, the elevation is gradual, equally distributed, and the slope is no more than medium steep.

The easiest way to notice the steepness of the relief is like this:

  • the further away the contour lines are, the flatter it is.
  • if the contour lines are at a medium distance, the slope will be medium steep as well.
  • the closer the contour lines are, the steeper the slope is.

2. From point D to point C there are several ups and downs, very steep parts, but also relatively flat parts.

Explanation:

If we start moving from point D to point C, the terrain will change several times. Initially, the movement will be upwards, through a medium steep slope, plateau like, which would not be a tough task. Then, as point B is reached on the way, we will have to go downwards, through a very steep slope, and most probably a special equipment will be needed for that.

As the very steep slope is passed, we still continue downward, just that the slopes are gradually becoming less and less steep, and we reach the lowest, flattest part of the river valley. Then, either by swimming, or by using a small boat or canoe, we pass the river, and continue in the relatively flat river valley.

The terrain starts to alleviate again. A slight slope will come on the way, and then gradual, medium slopes until we finally reach the point C.

On our way, we will go through:

  • low plateau
  • steep, rocky sides
  • river valley
  • a hill

3. The equipment needed for moving between points B and C will be alpine equipment, and maybe swimming equipment as well.

Explanation:

Between point be and point C there is a two tough obstacles for moving through. The first tough obstacle is the very steep relief just east of point B, while the other obstacle is the large river that lies roughly midway between these two points. These physical features are very tough for passing through, even for a person with experience in moving through such terrain, so special equipment is recommended.

Considering how steep the slopes is just east of point B, alpine equipment will be needed. This includes:

  • climbing boots
  • crampons
  • descender
  • screw gate
  • harness
  • climbing rope
  • helmet

The river, as mentioned, is relatively large, and while it is possible to swim through it without equipment, making it easier and faster is always recommendable. In such equipment are:

  • flippers
  • snorkel
  • goggles

4. The contour interval is 20 on this map.

Explanation:

The map we have presented is a map that shows us the physical features through contour lines. The contour lines are closed, circular lines that are connecting dots with the same elevation. Each contour line is marked with a a particular value, representing elevation in a particular unit, or it can every fifth, for example, which is marked with a particular value.

The interval represents the vertical distance between the contour lines. There might information about it on the legend of the map, or we might need to figure it out by ourselves, by analyzing the marked contour lines.

In this case, the interval is 20. This can easily be seen if we take the marked contour lines, and how many contour lines there are in between. For example, we have a 200 and 260 marked contour lines, and between them there are two contour lines, which naturally are equally distributed by elevation, so they will be 220 and 240.
