A phenomenon where saturated soil temporarily loses its strength due to the application of stress, such as during an earthquake or sudden loading.

• Liquefaction

• None of these

• Erosion

• Soil Collapse

• Landslide

This occurs when the pore water pressure within the soil increases to the point where it equals or exceeds the confining pressure, causing the soil particles to lose contact with each other and reducing the soil's shear strength.

• Liquefication

• None of these

• Landslide

• Weathering

• Erosion

This type of soil is characterized by its plasticity, meaning it can deform without cracking, and it typically has low permeability, making it less prone to erosion.

• non-cohesive soil

• cohesive soil

• sandy soil

• organic soil

• gravely soil

It is a measure of the amount of matter in an object or substance and a fundamental property that does not change regardless of the object's location, whether on Earth or in space.

• mass

• all of these

• volume

• weight

• area

Two observers stand 150 meters apart, between them stands a structure. The angle of elevation to the top of the structure from the first observer is 37.2 degrees, while the angle of elevation to the top of the structure from the second observer is 25.5 degrees. What is the height of the building?
