at a ocean - continent convergent boundary, what is the mechanism of melting that creates the first magma?

Answers

Answer 1

At a ocean-continent convergent boundary, Magma is created at convergent borders when water from a subduction zone plate works as a flux to reduce the melting point of the nearby mantle rock.

Magma occurs at divergent borders as a result of decompression melting. Within a mantle plume, melting also occurs during decompression. An ocean dominated tectonic plate collides with a plate made mostly of continental lithosphere to form oceanic-continental convergent boundary.

Surface materials that were trapped in the rocks of the subducting plate, also known as a slab, are altered and water vapor escapes when it is exposed to the extreme temps of the asthenosphere. This ocean creates magma by lowering the melting point of the surrounding rock. Along the overlaying continental crust, the magma rises and creates volcanic arcs in the mountains.

An unsaturated parcel of air in Boulder, Colorado, rises from a surface temperature of 24ºC and an elevation of 1655 m to an elevation of 4155 m without reaching the dew-point temperature. What is the temperature of the parcel at this elevation?

Answers

If an unsaturated parcel of air in Boulder, Colorado, rises from a surface temperature of 24ºC. the temperature of the parcel at an elevation of 4155 m is -1°C.

What is the temperature of the parcel at this elevation?

The rate at which an unsaturated parcel of air cools as it rises is known as the dry adiabatic lapse rate, and it can be used to solve this issue. According to 1000 metres of climb, the dry adiabatic lapse rate is around 9.8°C.

To start, we can determine the elevation change:

4155 m - 1655 m = 2500 m

The predicted temperature drop caused by the dry adiabatic lapse rate can therefore be calculated as follows:

9.8°C/1000 m x 2.5

= 24.5°C

= 25 °C (Approximately)

As a result, the parcel's temperature at 4155 m above sea level is:

24°C - 25°C = -1°C.

How can primitive meteorites be distinguished from processed meteorites?

A) Radiometric dating shows that primitive meteorites are slightly older.
B) Radiometric dating shows that primitive meteorites are slightly younger.
C) Primitive meteorites always contain iron and processed meteorites do not.
D) Primitive meteorites always contain rocky material and processed meteorites do not.
E) Primitive meteorites always contain carbon compounds and processed meteorites do not.

Answers

Primitive meteorites can be distinguished from processed meteorites based on their presence. The correct answer is E. Primitive meteorites always contain carbon compounds, while processed meteorites do not.

Primitive meteorites, also known as chondrites, are believed to be remnants of the early solar system and have undergone minimal processing or alteration since their formation. On the other hand, processed meteorites, such as achondrites, have undergone more significant geological processes, including melting and differentiation.

One key characteristic that can help distinguish between primitive and processed meteorites is the presence of carbon compounds. Primitive meteorites often contain organic compounds, such as amino acids and hydrocarbons, which are the building blocks of life. These carbon compounds are thought to have formed in the early stages of the solar system.

In contrast, processed meteorites typically do not contain significant amounts of carbon compounds. The geological processes they have undergone, such as melting and differentiation, have led to the loss or alteration of volatile components, including carbon compounds.

Therefore, the presence or absence of carbon compounds is a useful criterion for distinguishing between primitive and processed meteorites. Primitive meteorites are characterized by the presence of carbon compounds, while processed meteorites typically lack these compounds.

Why is it not necessary to indicate the texture of detrital rocks on the identification chart for sedimentary rocks

Answers

The texture of detrital rocks, which are composed of rock fragments and sediment grains, is not typically indicated on identification charts for sedimentary rocks because it is not a defining characteristic for their classification.

Detrital rocks are primarily classified based on their grain size and composition rather than their texture.  The grain size, which refers to the diameter of the sediment grains, is a crucial factor in classifying detrital rocks. The chart will typically include categories such as gravel, sand, silt, and clay, allowing for the identification of the dominant grain size present in the rock.

Additionally, the composition of the sediment grains, such as the mineral types or rock fragments, plays a significant role in classifying detrital rocks. Identification charts often focus on describing the composition of the grains, such as quartz, feldspar, or lithic fragments.

While texture can be important in some sedimentary rocks, such as those formed through chemical or biochemical processes, it is not as relevant in the case of detrital rocks. Therefore, identification charts for sedimentary rocks primarily emphasize grain size and composition as the key factors in classifying and identifying detrital rocks.

Answers

The energy from the core creates convection currents, which push magma through the lithosphere at the mid-ocean ridges to form new crust. This crust is then moved towards the subduction zones and recycled as it is pushed down by gravity into the mantle.

The Earth's core is a source of heat that generates convection currents in the mantle. These convection currents cause the magma to rise up through the lithosphere at the mid-ocean ridges, where new crust is formed through volcanic activity. This process is known as seafloor spreading. As the new crust forms, it pushes the older crust away from the ridge.

Over time, the older crust moves towards the subduction zones, where it is forced beneath another tectonic plate. This process is called subduction, and it allows the crust to be recycled back into the mantle, completing the cycle of plate tectonics.

N. Determine where a significant volcanic eruption would occur in the world, the entire United States, and the conterminous United States. Infer the types of hazards present, and relate all to plate tectonic theory.

Answers

A significant volcanic eruption is likely to occur in areas where tectonic plates are in contact or near each other. These areas are known as plate boundaries, and they are often associated with volcanic activity.

In the world, some areas with a high potential for volcanic eruptions include:

The Pacific Ring of Fire, which is a region around the Pacific Ocean where several tectonic plates meet and is home to many active volcanoes.

The East African Rift, which is a region in East Africa where the African Plate is splitting apart and is associated with a number of active volcanoes.

The Andes Mountains, which are a long chain of volcanic mountains in South America that are formed by the collision of several tectonic plates.

In the United States, some areas with a high potential for volcanic eruptions include:

The Cascade Volcanic Arc, which runs along the west coast of the United States and is formed by the collision of the Juan de Fuca Plate and the North American Plate. This region is home to many active volcanoes, including Mount St. Helens and Mount Rainier.

The Long Valley Caldera in California, which is the site of a major volcanic eruption that occurred around 760,000 years ago. The caldera is currently monitored for signs of renewed activity.

The Yellowstone Caldera in Wyoming, which is the site of a massive volcanic eruption that occurred around 640,000 years ago. The caldera is currently monitored for signs of renewed activity.

In the conterminous United States, the types of hazards present in areas with significant volcanic activity include:

Ashfall: Fine particles of volcanic ash can be dispersed into the air during a volcanic eruption and can cause respiratory problems if inhaled.

Lava flows: During a volcanic eruption, lava can flow down the slopes of the volcano and can cause destruction to anything in its path.

Pyroclastic flows: These are fast-moving clouds of hot gas, ash, and rock that can be triggered by a volcanic eruption. They can travel down the slopes of the volcano at high speeds and can cause widespread destruction.

Volcanic gas emissions: Volcanic eruptions can release a variety of gases, including sulfur dioxide, hydrogen chloride, and carbon dioxide. These gases can contribute to air pollution and can be harmful to human health if inhaled.

All of these hazards are related to plate tectonic theory because they are caused by the movement of the Earth's tectonic plates and the resulting changes in the Earth's crust and mantle. The movement of the plates can cause magma to rise to the surface, leading to volcanic eruptions. The location of volcanic activity is often related to the boundaries between tectonic plates, where there is a higher potential for magma to rise to the surface.

Peru's residents are familiar with Enso as it brings a warm current that reduces populations of Anchovies

A member of the family Engraulidae, an anchovy is a small, common forage fish. The majority of species are found in marine environments, however a few will also live in brackish water, and several are only found in fresh water in South America.

The silver-colored longitudinal stripe that extends from the base of the caudal (tail) fin gives anchovies their tiny, green color and their blue reflections. As adults, they grow to a length of 2 to 40 centimeters (1 to 15+12 inches), and their body forms vary, with more slender fish seen in northern regions.

Anchovies are dispersed across the oceans of the world, however they are more common in temperate regions and rare or nonexistent in extremely cold or extremely warm waters. In general, they are quite tolerant of a wide variety of temperatures and salinities. The shallow, brackish, muddy bottoms of estuaries and bays are good places to look for large schools of fish.
