By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.

∙ 16y agoThe only rock that can form from magma directly is Igneous rock. Since the Igneous rock is the only rock which is formed from magma by cooling and hardening. Molten rock is magma on Earth's surface. Therefore, the only rock that forms directly from magma is igneous rock.

What is the name of the chain of volcanoes that form at an oceanic to oceanic plate boundary?
When there is oceanic-oceanic convergence, one layer of oceanic lithosphere is subducted. This not only introduces water, which lowers the melting temperature of the asthenosphere, but can create an island with a volcano. This occurs when the hot magma rises from the subduction zone and build up in size. This would not have any specific name. If the volcano was situated on a hot spot, however, it would form linear island chains.

How do the igneous rocks granite and diorite form?
They form in essentially the same way, the only real difference being in composition. They form as magma slowly cools deep underground, allowing large crystals to form. Granite forms from magma that is rich in silica, sodium, and potassium. Diorite forms from magma that has somewhat less silica and more iron, calcium, and magnesium.

Does magma beneath the surface cool fast?

What are the properties of magma help to determine the types of eruptions?
Magma is a term for rock in liquid form. It differs from lava only in 1 respect, its location. Whilst lava is the name for liquid rock released from a volcano in an eruption, magma is the name for liquid rock found beneath the surface of a planet. The temperature for magma is around 700-1300 degrees Celcius.
What city is team magma hideout?
That depends on your version... In Ruby, it's in a cave to the East (right) of Lilycove City, which you can only access after confronting Team Magma at Mt. Pyre. In Emerald, the Team Magma Hideout is on the Jagged pass between Lavaridge City and the summit of Mt. Chimney. The entrance will not appear until you confront Team Aqua and Team Magma at Mt. Pyre, where Mt. Pyre's matron will give you the Magma Emblem, telling you that a member of Team Magma dropped it and that it must be a key of some kind.
