Igneous rock are formed by the cooling and crystallization of molten rock and are formed by the cooling of magma above earth's surface.
Let's look into the statements one by one:
Igneous rocks are formed only from material ejected during a volcanic eruption.
-This is not true because igneous rock can also be formed by the cooling down of magma inside a volcano or magma that was trapped in the crack of crust.
Igneous rocks are formed by the cooling and crystallization of molten rock.
-This is correct.
Igneous rocks are produced by the weathering and transport of pre-existing rocks.
-This is incorrect as igneous rock is formed by volcanism. The rock that are formed with the statement is sedimentary rock.
Igneous rocks are formed by the cooling of magma above earth's surface and lava below the surface.
-This is correct. Both intrusive and extrusive volcanic activity forms igneous rock after cooling down.
Igneous rocks are formed by recrystallization
-This is not true as recrystallization does not take place in the formation of the igneous rock. The rock formed by recrytillization is metamorphic rock.
Therefore,the igneous rock are formed by the cooling and crystallization of molten rock and are formed by the cooling of magma above earth's surface.

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.
