  1. Spread footing

  2. Pile foundation

  3. Mat foundation

  4. Raft foundation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Spread footings are commonly used for structures built on rock or hard soil because they can distribute the load of the structure evenly over a large area.

Multiple choice

What is the ideal slope for contour plowing?

  1. Less than 2%

  2. 2-5%

  3. 5-10%

  4. More than 10%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ideal slope for contour plowing is between 2% and 5%. Slopes that are too steep or too flat are not suitable for contour plowing.

  1. 10-20%

  2. 20-30%

  3. 30-40%

  4. 40-50%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

MBT technologies typically achieve a moisture content reduction of around 20-30%, depending on the specific technology and waste composition.

  1. Sinkholes

  2. Ground settlement

  3. Lateral spreading

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sinkholes are the most common type of geotechnical failure in subsidence, accounting for approximately 50% of all failures.

Multiple choice

What is the recommended slope for contour bunding?

  1. Less than 5%

  2. 5-10%

  3. 10-15%

  4. More than 15%
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Contour bunding is generally recommended for slopes ranging from 5% to 10%. Steeper slopes may require additional soil conservation measures.

Multiple choice

What is the primary factor determining the height of contour bunds?

  1. Slope of the land

  2. Soil type

  3. Rainfall intensity

  4. Crop type
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The height of contour bunds is primarily determined by the rainfall intensity in the area. Higher rainfall intensity requires taller bunds to effectively control runoff.

Multiple choice

The Universal Soil Loss Equation (USLE) is used to:

  1. Calculate soil erosion rates

  2. Predict climate change impacts

  3. Assess habitat fragmentation

  4. Determine water quality
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Universal Soil Loss Equation (USLE) is a mathematical model used to estimate the average annual soil loss from a field due to the combined effects of rainfall, soil type, slope, and land management practices.

Multiple choice

Which of the following is NOT a factor that influences the rate of water infiltration into soil?

  1. Soil texture

  2. Soil structure

  3. Vegetation cover

  4. Climate
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Climate is a factor that can influence the amount of water that falls on an ecosystem, but it does not directly influence the rate of water infiltration into soil.

Multiple choice

What is the main limitation of using seismic refraction in archaeological surveys?

  1. It is only effective in dry soils.

  2. It can only detect large buried features.

  3. It is sensitive to changes in soil moisture.

  4. It requires a lot of equipment and expertise.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Seismic refraction is a geophysical method that uses sound waves to image the subsurface. It is often used in archaeology to study the structure of archaeological sites, such as the layout of buildings and the depth of buried deposits. However, seismic refraction is limited in its ability to detect small buried features, as the sound waves can only penetrate a few meters into the ground.
