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.

Maps are an increasingly important source of information for government at all levels, because they are a great tool to place all kinds of information about a region: demographic information, economic information, physical geography information, and so on.
Lava that cools so quickly that the ions do not have time to arrange themselves into crystals with definite shape will form igneous rocks with FINE GRAINED TEXTURE. Igneous rocks are those rocks formed as a result of cooling of magma or lava.
