Civil engineers conducted a land survey in a hilly region, where roads were carved out between steep hillside slopes. Complete the passage to reveal the engineers’ safety recommendations for the area. The engineers noted that the area was prone to rockfalls and landslides. They proposed a plan to secure the rocky hillside slopes using . They also advised their team that if the slopes are not stabilized, could cause damaging mass movement without warning.
Mass wasting is movement of rock and soil down the hill. The rocky hillside slopes can be secured by slope reinforcement. if the slopes are not stabilized, landslide can cause damage.
What do you mean by mass wasting?Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity.
The most common types of mass wasting are slumps, rockslides, debris flows, and earthflow. Slumps are slow and short-distance downslope movements of semi-consolidated earth material on a curved or planar sliding surface.
The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil.

In sediments and waterlogged soil, dissolved O2 concentrations are so low that the microorganisms living there must rely on other sources of oxygen for respiration. Some bacteria can extract the oxygen in sulfate ions, reducing the sulfur in them to hydrogen sulfide gas and giving the sediments or soil a distinctive rotten-egg odor. What is the oxidation number of sulfur in these compounds
Answer:
SO₄²⁻ (+6)
H₂S (-2)
Explanation:
To determine the oxidation number of sulfur in a compound, we need to consider that the sum of the oxidation numbers of the elements present is equal to the charge of the compound.
Some bacteria can extract the oxygen in sulfate ions...
SO₄²⁻
1 × ON(S) + 4 × ON(O) = 2-
1 × ON(S) + 4 × -2 = 2-
ON(S): +6
...reducing the sulfur in them to hydrogen sulfide gas...
H₂S
2 × ON(H) + 1 × ON(S) = 0
2 × +1 + 1 × ON(S) = 0
ON(S): -2

work from home will have a future impact on urban sprawl?
Answer:
Yes, working from home will have a future impact on urban sprawl. Working from home reduces the need for people to commute to their workplace, which in turn reduces the demand for housing in urban areas. This can lead to a decrease in urban sprawl, as fewer people are commuting to urban areas and thus fewer people are in need of housing. Additionally, with fewer people commuting to urban areas, there will be less traffic congestion, leading to a reduction in air pollution.

Thinking about the types of chemical
bonds, would you rather be in a relationship
that is more similar to an ionic bond or more
similar to a covalent bond? Explain your choice.
Ionic bonds are preferred as they are stronger than covalent bonds.
Why Ionic bonds are stronger than covalent bonds?Ionic bonds result in a stable composite when all of the electrons between the components are transferred. While two elements only share electrons to form a stable molecule in a covalent bond.
Electrostatic force and Van Der Waals force are the forces that keep ions together and covalently linked elements together, respectively.
Cations and anions are created as a result of the complete transfer of electrons in ionic connections. As a result, these ions are attracted to one another strongly by electrostatic forces.
The Van Der Waal's force that exists between two covalently bonded elements is weaker than the electrostatic force because covalently bonded components only share electrons.
