The main way new oceanic crust is created is by eruption of lavas and solidification of magmas at depth.
How is new oceanic crust is createdThe main way new oceanic crust is created is by magmas along an ocean-continent convergent boundary. At these boundaries, magma rises up from the mantle and solidifies to form new oceanic crust. The other options listed do not involve the creation of new oceanic crust, but rather the modification or destruction of existing crust. Sediment scraped off a subducting slab may be incorporated into the overriding plate, but it does not create new oceanic crust.
Continents that subside below sea level and continental rifting both involve the modification of existing crust, but not the creation of new oceanic crust. The eruption of lavas and solidification of magmas at depth may result in the formation of new crust, but only in certain tectonic settings such as at divergent boundaries.

what two people groups have inhabited the british isles since before the romans conquered the southern half of great britain?
The 2 people groups that inhabited the British Isles since be-fore the romans conquered the south-ern half of great Britain were - The Brythons (Britain) and The Gaels.
Between 800 and 600 B.C., 2 groups of Celts from south-ern Europe invaded the British Isles. The Brythons (Britain) set-tled on the largest island, Britain. the 2nd groups was called the Gaels; they settled on the 2nd largest island, now called Ireland.

what are the nature and function of internal boundaries
Internal boundaries are physical or conceptual boundaries within a system or organization that separate different parts of the system or organization from each other. They can be physical, such as walls or barriers, or conceptual, such as policies or procedures.
The nature of internal boundaries can vary depending on the system or organization in question. They may be hierarchical, such as in a large corporation where there are distinct departments or divisions, or they may be more fluid and decentralized, such as in a small startup where team members collaborate across different functions.
The function of internal boundaries is to help organize and manage complex systems or organizations by separating different parts of the system or organization and creating clear lines of responsibility and accountability.
By separating different functions or teams, internal boundaries can help to reduce conflict and increase efficiency by allowing individuals to focus on their specific tasks or responsibilities.
However, internal boundaries can also have negative consequences if they are too rigid or inflexible. They can create silos and limit collaboration and communication between different parts of the system or organization, which can lead to inefficiencies and missed opportunities.
Therefore, it is important for organizations to carefully consider the nature and function of internal boundaries and ensure that they are structured in a way that promotes collaboration and innovation.

A conduit is an underground channel, a vent is an opening at the surface, and a crater is a bowl-shaped depression that can form at the summit or on the flanks of a volcanic cone
Conduit: A conduit is a narrow, vertical channel that connects the magma chamber deep below the Earth's surface to the volcanic vent or opening at the surface. It is the path that molten rock or magma travels through on its way to the surface during an eruption. The conduit can be several meters to several kilometers in length and can be lined with various types of volcanic rocks, including solidified magma or ash.Vent: A vent is the opening at the surface of the Earth through which volcanic material, including magma, ash, and gas, is ejected during an eruption. The vent can be a small or large opening in the ground, and its size and shape can change during an eruption. Crater: A crater is a bowl-shaped depression that can form at the summit or on the flanks of a volcanic cone or mountain.

injecting hot fudge into ice cream and causing the ice cream to melt is an appropriate analogy for which cause of magma melt?
The analogy of injecting hot fudge into ice cream and causing it to melt is a good representation of the process of decompression melting. Both involve the release of pressure and the subsequent heating up and melting of the material.
The appropriate analogy for this would be decompression melting. Decompression melting occurs when pressure on a rock is reduced, causing it to become less dense and heat up, leading to melting. In this analogy, the hot fudge would represent the heat, and the ice cream would represent the rock.
The act of injecting the hot fudge would represent the melting of magma. Decompression melting occurs because when pressure is reduced, the rock becomes less dense and the molecules become more mobile and able to move around. this causes the rock to heat up and eventually melt.
The process is similar to what happens when a gas is compressed and then released. the molecules move more freely, leading to an increase in temperature.

volcanoes are found at what plate boundaries
At plate boundaries, where tectonic plates are either convergent, divergent, or sliding past one another, volcanoes are frequently found.
Convergent plate boundaries: Where one tectonic plate is forced beneath another, a process known as subduction, volcanoes can form. When the subducting plate and the surrounding rocks melt, magma is produced that can rise to the surface and erupt as volcanoes.
These volcanoes, also known as stratovolcanoes or composite volcanoes, frequently experience violent eruptions. Examples include the Andes Mountains in South America and the Pacific Ring of Fire, a ring of volcanoes that surrounds the Pacific Ocean.
Divergent plate boundaries, where two plates are moving apart from one another, are another location where volcanoes can form.

in Wikipedia, look up "Volcanic arc" and answer this question: In which tectonic settings is magma caused by water lowering the melting temperature of rock?a. Subduction zones
b. Mid-ocean ridges
c. Hot spots
d. All the above
Option a is Correct. Look up "volcanic arc" on Wikipedia and respond to the following: Water causes magma in subduction zones because it lowers the melting point of rock there.
Magma is created at convergent borders when water from a subducting plate serves as a flux to reduce the surrounding mantle rock's melting temperature. Hot rock from below may intrude into the colder plate above when the denser tectonic plate subducts, or sinks below, the less dense tectonic plate.
This procedure generates magma while transferring heat. The magma in this subduction zone has the ability to form a volcanic arc, a group of active volcanoes, over millions of years. A volcanic arc is a sequence of volcanoes that develops above a subduction zone and can range in length from hundreds to thousands of kilometres.

in which tectonic settings is magma caused by water lowering the melting temperature of rock?
Magma caused by water lowering the melting temperature of rock is typically associated with subduction zones, where one tectonic plate is forced beneath another.
As the subducting plate sinks deeper into the Earth's mantle, it heats up and releases water and other volatile substances that are trapped within the minerals of the plate. This water rises into the overlying mantle wedge and lowers the melting temperature of the rock, causing it to partially melt and generate magma. The magma produced in this way is typically rich in volatiles and can be very explosive. Some of the world's most active and dangerous volcanoes, such as Mount St. Helens in the United States and Mount Pinatubo in the Philippines, are located in subduction zones.
