Above is an example seismogram from a famous 1989 earthquake in California recorded at a seismic station in Finland. Time is on the x-axis and ground displacement is on the y-axis. Notice that the ground displacement is measured in microns (1/1000 of a millimeter!). Identify the arrival times of the different types of seismic waves.
Answers
The S wave arrived at approximately 12 seconds while the P wave arrived at approximately 7 seconds.
How to calculate the distance?It should be noted that one can calculate the distance using the seismic travel time.
It can be deduced that the S wave arrived at approximately 12 seconds while the P wave arrived at approximately 7 seconds.
The time difference will be:
= 12 - 7
= 5

Disadvantages of contour farming
Answers
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.

Fractures along which rock has slipped relative to the other side are called faults, whereas fractures that are simple cracks where the rock has pulled apart by a small amount are joints.
What is fractures?A fragility fracture in one of the body's bones. An open or complicated fracture occurs when a shattered bone punctures the skin. Car accidents, falls, and sports injuries are all common causes of fractures. Low bone density and osteoporosis, both of which cause bone thinning, are further factors.

Answers
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.

What can people do to prevent desertification in the future?.
Answers
Planting more trees - the roots of trees hold the soil together and help to reduce soil erosion from wind and rain.
Improving the quality of the soil - this can be managed by encouraging people to reduce the number of grazing animals they have and grow crops instead. The animal manure can be used to fertilise the crops grown. Growing crops in this way can improve the quality of the soil as it is held together by the roots of plants and protected from erosion. This type of farming is more sustainable.
Water management - water can be stored in earth dams in the wet season and used to irrigate crops during the dry season. This is an example of using appropriate technology to manage water supplies in the desert environment.
Magic stones (or bunds) are circles of stones placed on the ground to hold water on the soil rather than letting it run quickly over the surface.
Drip irrigation is where water drips slowly onto the ground from pin-sized holes in a hose lying on top of the soil. This minimises water loss, maximises effectiveness and can be delivered via a solar pump.
