2. A subduction trench forms where the subducting plate bends downward into the mantle
1. An accretionary prism begins to form
4. Magma, created by flux melting of the mantle, rises through the overriding plate
3. Lava erupts onto the surface, forming volvanes
Volcanoes on the ocean floor erupt to create oceanic islands, often referred to as volcanic islands. Oceanic islands are also called as "high islands," regardless of their height. Low islands are continental and coral islands, which can be hundreds of metres taller than high islands. Even though they are encircled by water, continents are not categorised as islands because of their size. The smallest continent, Australia, is more than three times larger than the largest island, Greenland. In every ocean, lake, and river in the world, there are innumerable islands.

Answer:
A. Its government tried to kill ethnic minorities.
Explanation:
Sudan is a country in North-East Africa with a huge Islamic population.
<u>In the 21st century, Sudan faced punishment from the international community because of the genocide activities, in which the government of Sudan tried to kill ethnic minorities that include Darfur community. In the ongoing conflict in Western Sudan, ethnic minorities were raped, killed, displaced, wounded, and traumatized.</u>
The United Nations established a hybrid United Nations-African Union mission (UNAMID) to stop the Sudan genocide. This mission tried to intervene between non-signatory movements and government and tried to maintain the peace.
Hence, the correct answer is "A. Its government tried to kill ethnic minorities."

Explanation:
An open border is a border that enables free movement of people (and often of goods) between jurisdictions with few or no restrictions on movement, that is lacking substantive border control. A border may be an open border due to intentional legislation allowing free movement of people across the border (de jure), or a border may be an open border due to a lack of legal controls, a lack of adequate enforcement or adequate supervision of the border (de facto). An example of the former is the Schengen Agreement between most members of the European Economic Area (EFTA and the EU). An example of the latter has been the border between Bangladesh and India, which is becoming controlled. The term "open borders" applies only to the flow of people, not the flow of goods and services,[1] and only to borders between political jurisdictions, not to mere boundaries of privately owned property.[2]
Open borders are the norm for borders between subdivisions within the boundaries of sovereign states, though some countries do have controlled borders within the boundaries of the state (for example in the People's Republic of China between the mainland and the special administrative regions of Hong Kong and Macau). Open borders are also usual between member states of federations (such as the United States of America), though again in some instances movement between member states may be controlled via an internal passport system. Federations and confederations typically maintain external border controls through a collective border control system, though they sometimes have open borders with other non-member states (particularly enclaves, such as Switzerland and the European Union) through special international agreements.
Pervasive international border control is a relatively recent phenomenon in world history. In the past, many states had open international borders either in practice or due to a lack of any legal restriction. Many authors, such as John Maynard Keynes, have identified the early 20th century and particularly World War I as the point when such controls became common.[3]
There have been sporadic attempts to promote global open borders as a viable policy option.[4] Open borders quickly became popular after 1889.[citation needed] The International Emigration Conference held in Rome in May 1924 stated that anybody has the right to immigrate to a different country if they wanted to.[citation needed] Before the 1880s, migration to the United States was not fully controlled. During World War I it became easier for people to migrate from their country of origin to foreign countries.[citation needed] After World War II, countries were looking for many new workers, and Germany issued a guest work program to attract more people to work.[citation needed] Later, in the 1970s to 1980s strict borders were reinstated in industrialized countries.[citation needed] Currently, immigration is more restricted and harder for low-skilled and low-income people.[
Answer:
Outer core
