1. Now answer the following questions:

a) How many stations and sidelines are indicated?

b) Is this town serviced from a single or double track?

c) Name the river running through the town.

d) Name the river flowing into the Ceres dam.

e) How many separate living areas are indicated?

f) How high is the highest peak in the Witsenberg?

g) Determine the distance between the police station and the sideline (small station) Skoonvlei.

h) Explain why the contours in the region of the Aartappel River (north of the town) are far from each other, while northwest of Ceres they are very close to each other.

These topographic maps cannot be found in atlases. However, it can be ordered from The State Printer in Pretoria where they are prepared by cartographers from vertical aerial photos and orthophoto maps.

Assessment

Learning Outcomes(LOs)
LO 1
GEOGRAPHICAL ENQUIRYThe learner will be able to use enquiry skills to investigate geographical and environmental concepts and processes.
Assessment standards(ASe)
We know this when the learner:
1.1 identifies a variety of geographical and environmental sources relevant to an inquiry [finds sources];
1.2 organises and interprets information relevant to the enquiry from simple graphs, maps, and statistical sources [works with sources];
1.3 measures distances on globes atlases and maps using line scales [works with sources];
1.4 uses local maps and/or orthophoto maps to locate and investigate the issue and its context (compares with field observations) [works with sources];

Memorandum

Activity 1:

1. 4

2. single track railway

3. Dwars River

4. Koekedou River

5. Main town, second direct east of main town, third north east of main town Nduli.

6. Slab Peak 1 392 m

7. 6,2 cm × 50 000 = 310 000 cm ÷ 10 000 = 3,1 km

8. Aartappel River region is situated in the wide, even river valley, where contours are far from one other to represent a flat slope. The south western region is a higher, mountainous area with steep, mountainous slopes. The contours are therefore very close to one other.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
