Answer:
2. Why was it important to examine both the colour and the streak of your minerals?
Answer: Because the surface colour of individual minerals can vary considerably but the streak colour is vertually constant & is therefore more characteristic of the mineral.
3. Is lustre a good characteristic to use for the
identification of minerals? Why or why not?
Answer: Lustre can vary within a particular
mineral - calcite might be vitreous or it may be
dull. Using lustre for identity often requires a
fresh surface if the mineral in anyway oxidises.
4. You have been given a sample of quartz, which has a hardness of 7. How can you use this mineral to determine the hardness of other minerals?
Answer: If the quartz can scratch another mineral, you know that mineral has a hardnessof less than 7. If the quartz is scratched by another mineral, you know that mineral has a hardness of greater than 7.
6. Which property or properties did you find most useful in the identification of the mineral samples? Which properties were less useful? Be specific in your explanation.
Answer: The most useful is hardness, fracture, cleavage, streak & sometimes crystal habit. The least useful is colour.
Explain why the diagram shown in Figure 9 is an example of nature’s recycling system.
The diagram that is shown in Figure 9 is an example of nature's recycling system as nutrients can be lost from the system by leaching heavy rain.
What is a recycling system?A recycling system means through which recyclable materials are separated from the waste collected on-site and managed.
Trees drop leaves which form a leaf litter layer. The hot and humid conditions help this. Decomposers are responsible for the breakdown of organic material such as leaves, twigs, and dead animals.
They are vital in recycling nutrients and converting dead matter into a form that can be used and nutrients can be absorbed by the plants.

How does colonialism contribute to multiculturalism? Give me two examples.
Answer: Multiculturalism, like post-colonialism, is often seen as a coded way of speaking about race and about the dangerous processes through which race becomes a matter of culture. Some of the most important and influential strains of political commentary on multiculturalism have arisen from negotiation with indigenous populations in various national states. Those debates have been focused on problems of recognition, reparation, and sovereignty.

Disadvantages of contour farming
Answer:
1. Requires protected head ditches and waste-water ditches. Since the furrows run across the slope, these ditches generally rim directly down slope. To prevent erosion, you may need pipes or flumes for head ditches and drops, underground pipelines, or other structures to protect waste-water ditches.
2. Requires equipment turns on the field. Equipment used in planting, cultivating, and harvesting has to be turned on the field at the end of the spur, spike, and fill furrows.
3. Requires engineering layout. Fields must be carefully planned and then planted between staked guidelines, running across the field on the proper irrigation grade.
4. Requires control of water in furrows. A break may damage lower furrows and cause erosion.

The Big Bang theory uses "red-shift" as evidence to explain the beginning of the Universe. How does the red-shift from distant galaxies provide evidence for the beginning of the Universe?
Answer:
Evidence from red-shift Astronomers have discovered that, in general, the further away a galaxy is, the more red-shifted its light is. This means that the further away the galaxies are, the faster they are moving. This is similar to an explosion, where the bits moving fastest travel furthest from the explosion.
Explanation:
the further away a galaxy is, the more red-shifted its light is. This means that the further away the galaxies are, the faster they are moving.

What is the difference between an orthophoto and a Topographic map
Answer:
orthophoto: picture (corrected for viewpoint artifacts)
topo map: representational drawing (with contour lines)
Explanation:
An orthophoto is a pictorial representation of an area of the Earth; a topographic map is a drawing that uses colors, lines, and shapes to represent an area of the Earth.
orthophotoAn orthophoto is a photographic image of a portion of the Earth's surface that has been corrected to remove any artifacts of the viewpoint from which the photo was taken. Objects with a vertical aspect will have their appearance adjusted so they are presented on the orthophoto as though viewed from above.
In addition, its scale has been corrected so that measurements of distance made on one part of the orthophoto will have the same scale as those made on any other part.
An orthophoto may or may not have contour lines added.
topographic mapA topographic map is a drawing that represents the terrain of a portion of the Earth's surface. It does so using colors, shapes, and shading, along with contour lines. It generally will show place names, political boundaries, and other features that may not show up in a photograph.
As nearly as possible for its size and scale, it will be drawn so that distance measurements made on one part of the map will have the same scale as those on any other part.
__
The attachment shows an orthophoto on the left, and a topographic map of the same area on the right.
_____
Additional comment
Orthophotos have been created from photographic images taken from an airplane. From such a platform, any objects not directly under the plane will have an appearance that includes a side view. The object's location in the photograph will depend on the altitude of the plane and the height and distance of the object relative to the flight path.
Current technology allows photographic images of the Earth's surface to be taken from satellites at a much higher altitude. The adjustments required on such images tend to be smaller, as the viewpoint and elevation-related aberrations are nearly non-existent.
