Explanation:

Rwanda is being plagued by murder. The widespread murders began in Kigali and swiftly extended to the Worldwide reaction. Similar to how crimes against humanity were carried out all around the world in the former Yugoslavia.

Rwanda is being overrun with murder. One of the most infamous recent genocides, the Rwandan Genocide began in 1994 and lasted for only 100 days before it soon spread. The world community and UN peacekeepers looked on while almost one million ethnic Tutsis and moderate Hutus were massacred during this 100-day span between April and July 1994.

Furthermore, it's important to recognize that the Rwandan Genocide happened during a civil war. In 1990, a civil war between the military forces of the government and the rebel Rwandan Patriotic Front (RPF), which was commanded by Tutsi exiles in Uganda, broke out.

Hence, the Rwandan Genocide was a cruel action in history like Jews genocide done by Hitler in world war2.

No, it is not likely that landslides frequently occur on the moon.

This is because the moon does not have an atmosphere, meaning there is no air pressure that could cause erosion and weaken the lunar surface.

Additionally, there is no water on the moon which could cause weathering and contribute to the destabilization of the lunar surface.

The moon's surface is primarily shaped by impact cratering, which creates a landscape of craters and basins.

While there have been some observed landslides on the moon, they are typically small-scale events that occur due to moonquakes, impact events, or thermal stresses.

Thus, landslides are not likely to occur.

Traction is the result of friction between the tires and the road surface, which is caused by the weight of the car pushing the tires against the road due to gravity.

Traction is a crucial aspect of driving. It is the ability of a vehicle's tires to grip the road surface and move forward. Traction is the result of friction between the tires and the road surface. Friction is a force that opposes motion and is caused by the interaction between two surfaces. In this case, it is the interaction between the tire and the road surface. The amount of friction depends on several factors, including the surface roughness and the force pushing the two surfaces together.
In the case of a car, the force pushing the tires against the road surface is due to gravity. The weight of the car creates a force that pushes the tires against the road. The more weight, the greater the force pushing the tires against the road, which results in more traction.
Friction is not the only factor affecting traction. Other factors, such as the type of tire and the road surface, also play a role. The type of tire affects the amount of surface area in contact with the road, which affects the amount of friction. The road surface also affects traction, with rougher surfaces providing more traction than smoother surfaces.
The amount of traction depends on several factors, including the force pushing the tires against the road, the type of tire, and the road surface. Understanding these factors is important for safe driving and maintaining control of a vehicle.

If the lithospheric mantle is partially melted, the most likely composition of the resulting magma is a silica-undersaturated magma, which would have a higher concentration of iron and magnesium compared to an unmelted mantle.

This is because the partial melting process would cause the release of partial melting components (such as alkali elements and water) from the mantle, leading to a more enriched magma composition. However, the exact composition of the resulting magma would depend on various factors such as the degree of partial melting, the initial composition of the mantle, and any additional materials that may be involved in the process.  

The lithospheric mantle is a layer of the Earth's mantle that lies beneath the crust. It is the layer that makes up the majority of the mantle, and is located beneath the rigid, outer layer of the Earth known as the lithosphere. The lithospheric mantle is a viscous, solid rock that is composed of a mixture of minerals, including olivine, pyroxene, and amphibole. It is estimated to make up about 84% of the Earth's total mass, and is thought to have a temperature of around 550-750°C.

Young lava flows exhibit distinct characteristics. The correct answer is rough upper surface, steep flow fronts, and limited plant cover.

Their surfaces are often rough and jagged due to the rapid cooling and solidification of molten lava. These flows commonly have steep fronts where the lava advanced and spread, forming pronounced edges. Initially, young lava flows tend to lack significant plant cover, as the volcanic terrain is barren and lacks established vegetation.

Over time, however, plant colonization can occur, gradually transforming the once desolate landscape. It's important to note that sediments in low spots are not typically associated with young lava flows, as the flow itself deposits volcanic rocks rather than sediments.

Therefore, young lava flows a rough upper surface, steep flow fronts, and limited plant cover.

Steep drop in ocean volume and area is the correct answer. A broad, generally shallow undersea terrace of continental crust that forms the margin of a continent is known as a continental shelf.

Most continental shelves feature a topography known as ridge and swale, which is a gently sloping terrain. The geology of continental shelves is frequently comparable to that of the neighboring exposed area of the continent. About 8% of the earth's surface is made up of continental shelves. Sand, silt, and silty mud are typically present as a layer on continental shelves. Their surfaces have some relief, with a mix of shallow depressions, valley-like troughs, and minor hills, ridges, and hills. In a few instances, submerged canyons with steep walls and a V-shape carved deeply through the shelf and slope.

A simple thing you can do is use less electricity. For example, people use electricity for light a lot and they can reduce that by just not using it in certain times like in the day time, they can open their windows for sun light and turn the lights on in night time. People also use too much electricity on gadgets and electronics and they can reduce that by just not charging them too often and using them a bit less. By doing these methods you can maybe save around 10$ to 100$ or even more.

Humans impact on soils by damaging the structure of the soil (the shape of the soil peds). When the peds of soil are rounded it gives soil a crumby structure, which is the best structure for soil fertility. Overgrazing occurs when large numbers of animals are allowed to graze in one area for too long. In the Sahel region, animal ownership is considered the main criteria for defining wealth. Nomadic farmers allowed too many animals to graze the land than it had the ability to support, resulting in desertification. This is where the soil cannot sustain the herd numbers and is therefore gone beyond its ‘carrying capacity’. Herders then moved to marginal areas, which made the situation more dire. Alongside this nomadic farmers were gradually replaced by more sedentary farming practices and villages were established. Wells were sunk to provide water for animals; however, these wells used up groundwater further reducing soil fertility in the region. With an increasing population, more pressure on the land meant that farmers were forced to farm the land more intensively and remained in the one area for a longer period. Once the grazing animals removed the vegetation, the soil was exposed to the weather (wind erosion , also known as Aeolian erosion) resulting in soil erosion and eventual desertification.

The cause of the increase in water pollution in the watershed of Chesapeake Bay is an increase in stormwater runoff in urban areas.

The Chesapeake Bay has been experiencing water quality degradation for a long time. The main determinants of this degradation are high sedimentation, nitrogen, phosphorus, and increases in stormwater runoff in urban areas.

The high content of nitrogen and phosphorus mostly comes from various community activities such as the use of fertilizers, stormwater runoff, septic tanks, and air pollution. While sedimentation comes from the rate of erosion and material carried from the construction area.

Urban and suburban stormwater runoff generally comes from rooftops, parking lots, and other closed areas that are unable to absorb water so that pollution is carried away by flowing water.

For this reason, in order to reduce the high runoff water, it is necessary to develop an absorption area that can infiltrate the material better. At the same time, the use of pollutant materials must also be reduced and replaced with other alternatives that are more environmentally friendly.

Answer with Explanation:

"Arid soil" is more easily eroded than moist soil because it has a lesser amount of organic materials in it. The organic materials (earthworm, fungi, bacteria, etc.) help the soil become more stable. It also enhances biodiversity, which makes the soil more fertile because it makes it more porous. This means that it is able to facilitate both movement of air and water through the soil. The arid soil lacks in this property, thus, making it more prone to erosion.

Another reason is that the arid soil is made up of sand and silt. These do not bind the soil particles together because of lesser moisture content when compared to the moist soil that allows the soil particles to stay in-tact.  

Entering a port or beach during the daytime has various advantages over entering the same place during the night time.

The visibility during the daytime is one of the primary reasons why entering a port or beach during the daytime is better.In the day time, the pilot has better visibility. It becomes easier to identify the landmarks, buoys, and navigational aids with a clear view. This makes navigation relatively easy and helps in planning the entry and exit routes of the vessel safely.

 Furthermore, during the daytime, the daylight and sunshine aid the watchkeepers in monitoring the movements of other vessels in the vicinity. The chances of collision reduce in daylight, thereby minimizing the possibility of accidents or mishaps. Another advantage of daytime is that the winds are less strong.

During the day, the weather is usually calm, and the wind speed is lower compared to the night time. This helps in mooring, anchoring, and berthing of the vessel without much difficulty. During the night, the wind speed increases, making it challenging to berth and anchor the ship safely.

Therefore, entering a port or beach during the daytime is better than entering the same place during the night time.

If a mining geologist locates a horizontal seam of coal very near the surface of land, the mining method that the mining company will likely use to extract it is open-pit mining method.

This is because open-pit mining is the most efficient and economical method to extract coal deposits near the surface. Open-pit mining method is one of the surface mining techniques. It is also known as strip mining, open-cut mining, or open-cast mining.

In this mining method, the surface layer of soil and rock overlying the deposit is removed to extract the coal seam. In open-pit mining, large pits or "steps" are excavated in the ground, and the overburden (soil, rock, and other materials) are removed to reach the coal seam. Once the coal is extracted, the mining pit is refilled and replanted to restore the land to its original state.

The open-pit mining method is typically used for coal deposits that are less than 100 meters deep. Open-pit mining is cost-effective, efficient, and provides a high production rate. It is the preferred mining method for most coal mining companies.

The porosity of the soil sample can be calculated by dividing the total volume of void spaces (air and water) by the total volume of the sample.

Given that the soil sample has a total volume of 1 cm³ and is comprised of 0.25 cm³ of air and 0.35 cm³ of water, we can add these volumes together to get the total volume of void spaces:

Total volume of void spaces = Volume of air + Volume of water = 0.25 cm³ + 0.35 cm³ = 0.6 cm³

Now, we can calculate the porosity by dividing the total volume of void spaces by the total volume of the sample:

Porosity = (Total volume of void spaces / Total volume of the sample) * 100

Porosity = (0.6 cm³ / 1 cm³) * 100 = 60%

Therefore, the porosity of the soil sample is 60%. This means that 60% of the total volume is comprised of void spaces, while the remaining 40% is occupied by solid particles.
