Why does the magma from some volcanoes flow smoothly and relatively peacefully, while the magma from other volcanoes blasts forth violently and deals death over wide areas?

Answers

Answer 1

The magma from some volcanoes flow smoothly and relatively peacefully, while the magma from other volcanoes blasts forth violently and deals death over wide areas because of Viscosity of Magmas.

Through cracks in the rock, magmas rise upward from the Earth's mantle. The viscosity, or flow resistance, of a magma relies on its water and silica content, which in turn affects the magma's own flow velocity. Magmas with a higher percentage of silica are more viscous and move more slowly than magmas with a lower concentration of silica. Volcanoes frequently contain thicker, more viscous lava with a high gas concentration when tectonic plates collide.

The inability of the gases to quickly boil out makes this mixture explosive.  Until the magma's pressure can no longer support them, the gases are locked there. They blast the magma into pieces at that time, which is often when the magma approaches the Earth's surface.

a. Reef
b. Swamp
c. Coastline
d. desert

Answers

d. desert

The Powder River Basin of Wyoming and Montana has been the most productive coal basin in the United States between 2014 and 2018. This is due to the vast coal deposits located underneath the surface that are easily accessible. In this region, the coal is mainly found in the form of lignite, a low-grade coal that is most commonly used to generate electricity. The basin also contains substantial amounts of subbituminous coal, which is used to produce synthetic natural gas.

The Powder River Basin is ideal for coal mining as it is a flat terrain that is easily traversed and the deposits are located close to the surface. The coal industry in the basin has been booming since 2014, when coal production reached a record high of 447 million short tons. This is due to the abundance of coal resources located in the region and the relatively inexpensive production costs. The Powder River Basin is an example of how the right geological conditions can lead to a successful mining industry.

how does the map above illustrate the concept of hierarchy

Answers

The given map above illustrates the concept of hierarchy by showing the different levels of authority and power within a society. Hierarchy is a system of organization in which people or groups are ranked one above the other according to status or authority.

In the map, we can see that the different colors and labels represent different types of cities, indicating a clear hierarchy. In particular, the map illustrates the concept of hierarchy through the following points:

Size: The size of the circles indicates the importance of the city. The larger the circle, the more important the city is. This implies that the bigger cities have more power and control than the smaller cities. For example, London, which is the largest circle on the map, is the capital city of the UK, and as such, it holds more political, economic, and social power than other cities.

Level of specialization: The labels on the circles indicate the level of specialization of the cities. For instance, the labels "Financial and commercial center" and "Research and Development" indicate that these cities are specialized in certain fields. These cities have a higher level of expertise and control in their respective areas of specialization than other cities.

Rankings: The different colors of the circles indicate different ranks of the cities. The blue circles indicate that the cities are world cities, while the yellow circles indicate that they are regional cities. This implies that the blue cities have more power and influence than the yellow cities, as they are recognized globally and have a bigger impact on the world stage.

In summary, the map shows a clear hierarchy of power and authority based on the size, level of specialization, and rankings of the cities. The larger, more specialized, and higher-ranking cities have more power and control than the smaller, less specialized, and lower-ranking cities.

Identify the boundary type that is being described. oceanic-oceanic convergent boundary transform boundary continental-continental convergent boundary oceanic-oceanic divergent boundary

Answers

An oceanic-oceanic convergent boundary is being described when two oceanic plates collide. This type of boundary occurs when one oceanic plate subducts or goes under the other.

During this process, the denser plate, which is usually older and cooler, sinks into the mantle beneath the other plate. As the subducting plate descends, it creates a deep oceanic trench, such as the Mariana Trench in the western Pacific Ocean.
The sinking plate can cause melting in the mantle, leading to the formation of volcanoes on the overriding plate. These volcanoes create volcanic island arcs, like the Aleutian Islands in the North Pacific.
This type of convergent boundary can also lead to the formation of earthquakes due to the intense pressure and stress that builds up as the plates collide and interact with each other.
In summary, an oceanic-oceanic convergent boundary occurs when two oceanic plates collide, leading to the formation of deep oceanic trenches, volcanic islands, and earthquakes.

The fossil record is one sort of evidence that has been used to support the Theory of Continental Drift. In rocks that are similar in age, scientists have discovered fossilized remains of related plant and animal species.

One of the earliest hypotheses put up by geologists for how continents might migrate over time is continental drift. Since then, the science of plate tectonics has supplanted the hypothesis of continental drift. The scientist Alfred Wegener is most strongly linked to the concept of continental drift.

He used the phrase "continental drift." Pangaea Wegener was persuaded that the continents of Earth had once been part of Pangaea, a single, vast landmass. Wegener, an astronomer by training, explained Pangaea using geology, biology, and botany and continental drift.

what is itcz and how does the wind blow in itcz, including surface wind, upper-level wind, and the vertical air movement that connnecting them?

Answers

The Intertropical Convergence Zone (ITCZ) is a region near the Earth's equator where trade winds converge. The region is also characterized by cloudy skies, rainy weather, and low pressure.

The ITCZ's location varies seasonally, moving north or south of the equator depending on the location of the sun. The ITCZ's position is determined by the location of the sun, which is directly overhead at noon at the equator, causing the air to rise and creating a low-pressure region.

As the air rises, it cools and condenses, resulting in rain and thunderstorms. The ITCZ's surface winds are the trade winds, which move towards the equator from the northeast in the Northern Hemisphere and the southeast in the Southern Hemisphere.

The upper-level winds are known as the easterly winds, which blow from east to west. They are responsible for bringing moisture from the Atlantic and Indian Oceans to the ITCZ. The vertical air movement is the convergence of the trade winds, which causes air to rise and creates a low-pressure zone.

The rising air cools and condenses, resulting in the formation of clouds and precipitation. As a result, the ITCZ is responsible for much of the Earth's precipitation.

How could the movements of the planets in the solar system be used as evidence for how the solar system formed?

Answers

The planets orbit the Sun in the same direction and have nearly circular orbits. This suggests that the solar system formed from a rotating cloud of gas and dust that began to collapse in on itself due to gravity.

Thus, the movements of the planets in the solar system can provide evidence for how the solar system formed. As the material spun faster, it flattened out and eventually formed the planets and their orbits.

The motions of the planets are also affected by the presence of the other planets in the solar system, indicating that the planets formed together rather than separately.

This also explains the reason why the planets closer to the sun are rockier and the planets far away are rather gaseous while spinning the rocky particles might be attracted more strongly. This evidence is consistent with the current understanding of the formation of the solar system.
