Which of the following describes the formation of an island arc?
As a lithospheric slab is being subducted the slab melts when the edges reach a depth which is sufficiently hot. Hot remelted material from the subducting slab rises and leaks into the crust forming a series of volcanoes. These volcanoes can make a chain of islands called an “island arc”.

What is seamount quizlet?
What is a seamount? An active volcano that occurs along the crest of the mid-ocean ridge. … Seamounts subside as tectonic plates move. Coral reefs grow away from the seamount in order to stay near the sunlight.
What was formed when oceanic plate converges with another oceanic plate?
When two oceanic plates converge the denser plate will end up sinking below the less dense plate leading to the formation of an oceanic subduction zone. … Whenever a subduction zone is formed the subducted plate will end up being partially melted by the earth’s internal magma and molten.

When was the ocean formed?
about 3.8 billion years ago
The ocean formed billions of years ago. Water remained a gas until the Earth cooled below 212 degrees Fahrenheit . At this time about 3.8 billion years ago the water condensed into rain which filled the basins that we now know as our world ocean.Apr 9 2021
How are volcanoes formed?
A volcano is formed when hot molten rock ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool forming the distinctive volcano shape shown here. As a volcano erupts it spills lava that flows downslope. Hot ash and gases are thrown into the air.
