Primary waves travel the fastest of energy waves produced by earthquakes and can travel through solids, liquids or gases, whereas Secondary waves are slower and can travel through solids only.
The waves that can pass through the earth's strata are body waves. They are the first waves that seismographs can record because they are the fastest waves. All states of matter, such as molten lava and rocks, are permeable to body waves. The earliest waves that reach a seismograph are known as P waves, or primary waves. The fastest seismic waves, known as P waves, may pass through solid, liquid, or gas. On the medium they pass through, they leave a trail of compressions and rarefactions. The second waves to come during an earthquake are called S waves, or secondary waves.
Seismic waves are the energy waves that go through the ground and are responsible for earthquakes and other related occurrences. Seismic waves come in two varieties: body waves and surface waves.

Sea arches and sea stacks provide evidence of weathering and erosion. In three to five sentences, explain the roles weathering and erosion play in creating these landforms and how deposition is involved in shaping the shorelines
Weathering and erosion aid in the creation of these sea arches by dispersing the pieces and preventing stones from falling.
Sandstone arches and polished cliffs braced against furious waves are examples of natural wonders created and revealed as a result of erosion's aid in the passage of the pieces. Longshore drift, the process by which sand and silt are moved down the coast, results in deposition along the shore. Sand and silt buildup results in coastal features like spits, which are lengthy landforms that stretch from the coast into the entrance of a nearby bay.
When it comes to molding and disintegrating rocks, weathering may be compared to a mechanical and chemical hammer. The geological processes of weathering and erosion are responsible for the movement of rock pieces and particles, and they also play a significant role in the creation of landforms.

#SPJ11
To produce a commercially viable oil deposit, there must be a source rock, a reservoir rock, a seal rock, and a trap that denies the oil passage to the surface.
The source rock is typically a sedimentary rock rich in organic materials, which under heat and pressure, generate hydrocarbons like oil and gas. The reservoir rock is a porous and permeable rock that stores the hydrocarbons, allowing them to flow through its interconnected pore spaces. Common reservoir rocks include sandstones and limestones.
The seal rock is an impermeable layer that prevents the hydrocarbons from escaping and migrating to the surface. Seal rocks, often made of shale or mudstone, create a barrier that keeps the hydrocarbons within the reservoir rock. Lastly, the trap is a crucial geological feature that stops the oil from reaching the surface. Various types of traps can be found, including structural traps (formed by deformation, such as folds and faults) and stratigraphic traps (created by changes in rock properties like permeability).
Together, these elements make up a complete petroleum system, which is necessary for the formation of a commercially viable oil deposit. Without any of these components, the oil may not accumulate in significant quantities, or it may not be economically feasible to extract it.
Therefore the correct answer is a trap that denies the oil passage to the surface.

Which particles of sediment are most likely to be transported as suspended load?
A. Small, low density particles
B. Pebbles of average density
C. Sand and gravel of relatively high density
D. Dissolved ions in solution
E. All of these
Answer:
A
Explanation:
The particles of sediment that are most likely to be transported as suspended load are small, low-density particles. These particles have a small enough size and low enough density to be easily carried along by the flow of water or air without settling out too quickly.
Pebbles of average density (Option B) are too large and heavy to be transported as suspended load. Instead, they are typically transported as bed load or rolled along the bottom of a river or stream.
Sand and gravel of relatively high density (Option C) can be transported as suspended load in very fast-moving water, such as during floods or other high-energy events. However, they are more likely to be transported as bed load.
Dissolved ions in solution (Option D) are not considered sediment and are transported as part of the water itself, not as suspended load.
Therefore, the correct answer is Option A: small, low density particles.

Every 15 degree eastwards the time is 1 hour later so that when it is 2 pm in london, it is 8 pm in dhaka. at this time, what do the clocks in manila say?
Every 15 degree eastwards the time is 1 hour later so that when it is 2 pm in london, it is 8 pm in dhaka. at this time, what do the clocks in manila say 10 pm.
Based on the given information, we know that London is at 0 degrees longitude and Dhaka is at 90 degrees east longitude. Therefore, the time difference between London and Dhaka is 6 hours (15 degrees eastwards = 1 hour later, so 90 degrees eastwards = 6 hours later).
If it is 8 pm in Dhaka, then it would be 2 pm in London - this is the time difference we already know.
To find out what the time in Manila is, we need to know its longitude. Manila is located at approximately 120 degrees east longitude.
Every 15 degrees eastwards from London means an hour later, so we can calculate the time difference between London and Manila as follows:
- London to Manila is 120 degrees eastwards from London
- 120 divided by 15 is 8
- Therefore, the time difference between London and Manila is 8 hours
If it is 2 pm in London and the time difference between London and Manila is 8 hours, then the time in Manila would be 10 pm.
Therefore, the clocks in Manila would say 10 pm at this time.

What forces have helped shape plant life in Africa South of the Sahara?
(Long answers would be great,I have a section of an essay due on this question)
There are many forces that have helped shape plant life in Africa south of the Sahara, including climate, geology, fire, and human activities.
Climate: The climate of Africa south of the Sahara is characterized by a tropical and subtropical climate, with distinct wet and dry seasons. This climate has led to the evolution of many different types of plants, including drought-resistant grasses, succulent plants, and deciduous trees.
Geology: The geology of the region has also influenced plant life. The high levels of volcanic activity have produced nutrient-rich soils that support a diverse range of plant life.
Fire: Fire is a natural part of the African savanna ecosystem, and many plants have adapted to survive regular fires. For example, some trees have thick bark that protects them from fire, while others have developed the ability to resprout from their roots after a fire.
Human activities: Human activities, such as agriculture and deforestation, have also had a significant impact on plant life in the region. Many native plant species have been replaced by crops and non-native species, and large areas of forest have been cleared for agriculture and settlement.
Overall, these and other factors have contributed to the rich and diverse plant life found in Africa south of the Sahara
Answer:
Saharan vegetation is generally sparse, with scatt3d concentrations of grasses, shrubs, and tress in the highlands, in oasis depressions, some heat and drought-tolerant grasses, herbs, small shrubs, and trees and found on the less well watered plains and plateaus of the Sahara.

a, price floor
minimum wage
b. rationing black market
Answer:
Explanation:
a. A price floor is a government-imposed minimum price that is set above the equilibrium price of a good or service in a market. The minimum wage is an example of a price floor, as it sets a minimum wage rate that employers must pay to their workers. Therefore, the minimum wage is a specific type of price floor.
b. Rationing is a system of allocating scarce resources, such as food or fuel, based on a set of criteria or rules. In times of shortage, a black market may emerge, which is an illegal market in which goods or services are bought and sold at prices that are higher than the legally established price. Rationing and black markets are related because they both arise as a response to scarcity, but they represent two different ways of allocating resources. Rationing is a legal and controlled method of allocating scarce resources, while black markets are illegal and uncontrolled.

In what direction must the airplane deflect its path to be certain it ends up landing in Peru?
From Wallace's viewpoint in space, Earth at the South Pole appears to be rotating in a counterclockwise direction.
This is due to the Coriolis effect, where objects on Earth's surface appear to move in a curving path due to the Earth's rotation. The airplane must deflect its path to the left to ensure it ends up landing in Peru.
This is due to the fact that the winds in the atmosphere are also affected by the Coriolis effect, causing them to flow clockwise in the Southern hemisphere and counter-clockwise in the Northern hemisphere.

One reason why superimposed drainage does not change it's course
A river or stream cutting through existing rock strata to create a new route for the water to travel is referred to as superimposed drainage. When the land's surface is raised or when the river's base level falls, this process can take place.
Unless there is a considerable change in the topography, a river or stream is unlikely to change its course once it has made a new passage through the rock strata. This is due to the fact that the structure and makeup of the rock strata, as well as the slope of the ground, both affect the river's course. Even while the river could wash away the rocks over time, it is unlikely that it will alter its path until the slope or make-up of the terrain significantly changes.
For instance, if the ground falls or is elevated, the land's slope may vary, changing the river's flow. The river, even if it is overlaid on top of preexisting rock strata, is likely to continue running along its established course if the ground is stable.

4.1 Name and Describe FIVE conditions that led to the formation of cyclone Freddy
Answer:
Warm temperature at sea surfaces.
Coriolis force impact area that forms a low-pressure zone.
Atmospheric instability.
Increased humidity in the lower to middle levels of the troposphere.
Low vertical wind shear.
Explanation:
Warm, moist air over the ocean rises due to less density. This air rises up and away from the ocean surface, leaving less air near the surface, creating a low-pressure zone.
Due to the surrounding high-pressure areas, air flows into this low-pressure area and eventually warms up, forming a cycle.
Now, this cycle makes the warm air above the ocean rise and cool the water below to generate clouds. With the constant heating and evaporating process, the entire cloud and wind system spins and grows.
With more speed, cyclone eye formation takes place in the centre. This zone signifies the lowest air pressure and is calm and clear. The high-pressure air from above flows down into this region.
When the wind’s rotating speed reaches 63 kmph, it is called a tropical storm. However, when wind speed reaches 119 kmph, tropical cyclone formation takes place.
Now that you know how a cyclone is formed, let's look at the categories of a cyclone.

-inadequate competition
-oligopolies
Monopolistic competition is separated from pure or perfect competition by product differentiation.
In a monopolistically competitive market, firms produce differentiated products, which means that each firm has some degree of market power to charge a slightly higher price than competitors. This differs from perfect competition, where all firms produce identical products and have no market power.
Hope that helps! Good luck! :)
Monopolistic competition is separated from pure or perfect competition by product differentiation. In pure or perfect competition, all firms in the market produce homogenous goods and have no control over the price.
On the other hand, monopolistic competition has firms that produce slightly different products, and they have a certain level of control over the price of their products. This is because consumers may be willing to pay more for a particular product, even if it is similar to another.
Moreover, in monopolistic competition, firms have a profit motive, which drives them to produce the best possible product and to be efficient in their production. Inadequate competition and oligopolies are characteristics of other market structures such as monopolies and oligopolies, respectively.
In conclusion, product differentiation is the main characteristic that distinguishes monopolistic competition from pure or perfect competition. This differentiation allows firms to have some control over price and to strive for profits, which is not the case in pure or perfect competition.
