magma is created by melted rock from the section of the earth called mantle which lies underneath the crust.
it is just called molten rock, and it comes out of the Earths crust via volcanoes. you can also say that its melted lava
If it reaches the surface, it is magma or lava. If it merely intrudes into rocks already formed, it is intrusive. Such as sills and dikes.
when melted rock cools that in the beggining is lava it transforms in an igneous rock

Volcanoes do not cause rocks to melt, they are just the exit where melted rock come to the earths surface.

rock cools quickly from melted rockRock cools quickly from melted rock.
Molten rock collects in a magma chamber beneath the volcano.
Yes. Obsidian is igneous rock by definition. It is found in or near volcanoes and is rock that has been melted and solidified.

Magma is rock that useally comes from a volcana it melts due to the high pressure and heat
no, if it is melted, it is igneous
When Volcanoes erupt the surface is melted by the lava
When a volcano erupts, it releases hot melted rock called magma, which then solidifies into solid rock. When enough of this rock has been released underwater, the result is an island.
and island arc is formed by undersea volcanoes. built over time, and island arc is made of basalt and melted rock from the mantle.
