The melt is therefore crustal and felsic in nature. However the magma erupted at Vesuvius has a significant mantle (mafic) contribution.
More than 60 feet of silt and volcanic debris covered Herculaneum. Later, some Pompeii inhabitants came back to rescue their belongings from their burned homes, but many artefacts were left behind and forgotten. However, the adjacent Mount Vesuvius volcano erupted in the summer of A.D. 79. It sent 20 kilometres of hazardous gas and smoke into the air, which quickly reached the town. Pompeii and many of its 10,000 inhabitants perished under a layer of ash almost instantly. The wall of death that buried the historic Roman city of Pompeii was a pyroclastic flow.

describe an earlier occasion when salvius, through his inaction, could have caused harm to cogidubnus.
Quintus lived in the house of Salvius all winter. He often visited the castle at the open invitation of King Cogidubnus.
Quintus told many stories about his lovely life, because the king always wanted to hear something new. As spring approached, Cogidubnus fell seriously ill. Many doctors visit the palace in search of treatment. But the disease worsened. The king and Quintus and Salvius sought advice how to cure.—It is in the city of Aquae Sulis.
Cogidubnus answered: "Many of the Saints who drink water from this spring will recover after this. An architect sent by the Romans to build a great bath near here. Near the baths is the temple of the goddess Sulis, built by my craftsmen .I often honor this goddess: perhaps it will get me a greeting Salvius, you are very cunning: I want you to speak with me.

what are the two air mases that have the greatest influence on the weather east of the rocky mountains in north america?
Answer:
The polar air mass and the Gulf of Mexico air mass
Explanation:
The two air masses that have the greatest influence on the weather east of the Rocky Mountains in North America are the polar air mass and the warm, moist air mass from the Gulf of Mexico. The polar air mass is typically cold and dry, and can bring cold temperatures and clear skies to the region. The warm, moist air mass from the Gulf of Mexico is typically warmer and more humid, and can bring mild temperatures and precipitation to the region. These two air masses can interact and combine to produce a variety of weather conditions, including snowstorms, thunderstorms, and tornadoes. The specific type of weather that occurs in a given location can depend on a number of factors, including the time of year and the location's geography.
in the climate system, which phase of water is most dense? a. gas b. liquid c. solid d. all have the same density.
The correct answer is b. liquid in the climate system, which phase of water is most dense.
When water is in the liquid phase, its density is highest at roughly 4 °C (39.2 °F). Since ice is more buoyant than water, it develops at the surface of bodies of water and freezes downward. Ice is a kind of solid water that is less dense than liquid water. Because of the way hydrogen bonds are oriented, ice has a lower density than water because the molecules are forced apart more. The unit of density is mass (g) per cubic millimetre (cm3). Water is least dense at 0°C and most dense at 3.98°C (freezing point). Salinity and temperature have an impact on water density. A stiff open lattice of hydrogen-bonded molecules, like a web, is created when water freezes at absolute zero degrees.

The values of B and C in the triangle are 40° and 55° respectively.
How to calculate the value of the angles in a triangle?It should be noted that the value of the total angles on a triangle is 180°. In this case, the angles are given as:
A = 85
B = 3x - 20
C = 2x + 15
This will be illustrated as:
85 + 3x - 20 + 2x + 15 = 180
Collect like terms
80 + 5x = 180
5x = 180 - 80
5x = 100
Divide
x = 100 / 5
x = 20
Therefore B will be:
= 3(20) - 20
= 40°
C = 2x + 15
C = 2(20) + 15
C = 40 + 15
C = 55°

Walking among the top canopy in a tropical rainforest requires _______.
a. bridges suspended almost 100 feet off the ground b. bridges suspended almost 60 feet off the ground c. bridges suspended almost 20 feet off the ground d. no special conditions
Answer:
a. bridges suspended almost 100 feet off the ground
Explanation:
It is difficult to determine exactly how high a bridge would have to be suspended above the ground to walk among the top canopy in a tropical rainforest, as the height of the canopy can vary depending on the specific location and the type of trees present. In general, however, the canopy of a tropical rainforest is typically found at a height of around 30-40 meters (100-130 feet) above the ground. This means that a bridge would need to be suspended at least this high in order to allow people to walk among the canopy. Keep in mind that this is just a general estimate, and the actual height of the bridge would depend on the specific conditions of the forest where it is located.
the principle that physical processes we observe today also operated in the past at roughly the same rates, and that these processes were responsible for the formation of geologic features that we now see in outcrops is called the principle of
The belief that the same natural rules and processes that govern the universe today and have always governed it in the past and apply to all of it is known as uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle.
According to the uniformitarian concept, the past may be understood via the present. The science of geology has been greatly impacted by this idea. According to uniformitarianism, the forces and processes in operation now have been in place for a very long period. The three conditions or concepts that made up the theoretical framework Lyell outlined in 1830 were as follows: 1) The uniformity principle, which claims that geological occurrences in the past must be explained by the same forces that are active now; 2) the uniformity of rate principle, which states that geological laws have the same power.

Vegetation's spectral characteristics. Chlorophyll regulates the spectral characteristics of vegetation in the visible region of the spectrum.
In vegetation, the reflectance spectrum in the visible area is dominated by light absorption by leaf pigments (400–700 nm). Red and blue (400–500 nm) wavelengths are preferentially absorbed by chlorophyll pigments a and b. Chlorophyll is the photosynthetic component that enables plants to produce carbohydrates by photosynthesis from carbon dioxide and water.

what variables would you investigate to determine what causes a rock to change into another type?
Answer:
1. The type of rock
2. The conditions of the environment
3. The presence of living organisms
4. The duration of the change
Explanation:
To determine what causes a rock to change into another type, there are several variables that would need to be investigated. These variables could include:
The type of rock: Different types of rocks have different compositions and structures, and they are more or less susceptible to certain types of changes. For example, some rocks, such as granite, are more resistant to weathering and erosion, while others, such as shale, are more easily altered.
The conditions of the environment: The forces of nature, such as heat, pressure, and the action of water and air, can all affect the stability of rocks and cause them to change over time. The specific conditions of the environment, such as the temperature, the pressure, and the presence of water or other chemicals, can all play a role in determining how a rock will change.
The presence of living organisms: The activities of plants, animals, and other living organisms can also affect the stability of rocks and cause them to change over time. For example, the roots of plants can exert pressure on rocks and cause them to crack or break, and the burrowing of animals can create spaces within the rock that allow water and other substances to enter and alter its composition.
The duration of the change: The length of time over which a rock is subjected to changing conditions can also play a role in determining how it will change.
How can climate change affect natural disasters?
Answer:Climate change can affect natural disasters in a number of ways. For example, rising global temperatures can lead to more frequent and severe heatwaves, droughts, and wildfires. Warmer temperatures can also cause glaciers and polar ice caps to melt, leading to sea level rise and an increased risk of flooding. In addition, extreme weather events, such as hurricanes and storms, can become more intense and destructive as a result of climate change. These changes can have a significant impact on communities and ecosystems around the world, and can exacerbate the damage caused by natural disasters.

if the black rock is igneous, like the granite, but extremely dark and fine-grained, what is a reasonable field name to give it?
Basalt is a fine-grained mafic igneous rock. It is commonly vesicular and aphanitic.
The pace at which the melt cools determines whether an igneous rock has a fine- or coarse-grained texture: slow cooling allows for the formation of massive crystals, whereas quick cooling results in microscopic crystals. Based on their chemical makeup, igneous rocks may be categorised into four groups: felsic, intermediate, mafic, and ultramafic. Figure 7.6's representation of Bowen's reaction series demonstrates how variations in an igneous rock's chemical composition correspond to variations in its mineral content. Since the crystals are too tiny to view without a magnifying glass, igneous rocks that are formed on the surface of the earth have a highly fine-grained structure.

Volume of sphere is V = (4/3)πr3
Area of the sphere is A = 4πr2.
where r= radius of the sphere
The question is incomplete that is the answer provide is of the question how to find surface area from volume:
The formula for surface area of a sphere is given by SA= 4/3π(r^2) (let us assume this as step 1), while its volume (V) is equal to (4/3)π(r^3) where "r" is the radius of the sphere.
To calculate the surface area for a sphere with a volume of 4.5π cubic meters where π= 3.14 approximately.
Step 2: The radius of the sphere by substituting 4.5π ft^3 for V in the formula in Step 1 to get:
V=4.5π cubic feet.= (4/3)π(r^3)
Step 3: Multiply each side of the equation by 3 and the equation becomes: 13.5π cubic feet =4π(r^3)
Step 4 : Divide both sides of the equation by 4π. Solve for the radius of the sphere.
To get:
(13.5π cubic feet)/(4π) = (4π )(r^3)/ (4π),
which then becomes: 3.38 cubic feet= (r^3)
Step 5: After calculating the value of "r" is 1.50ft
Therefore, putting the value of r in step 1; we get
SA = 4π(1.50^2) = 4π(1.50X1.50) is equal to 9π square ft.
