Are geological features created by rhyolitic magma Rhyolitic magma promotes eruptions?
Lava domes are large geological features created by rhyolitic magma. Rhyolitic magma promotes plinian eruptions. Plinian eruptions can happen very quickly and shoot lave several miles into the air.
What happens when you have divergent boundaries by submarine eruptions and intrusions of rhyolitic magma?
When divergent boundaries are associated with submarine eruptions and intrusions of rhyolitic magma, it can lead to the formation of new oceanic crust. Rhyolitic magma is rich in silica and tends to be more viscous, resulting in explosive eruptions that can build underwater volcanoes and contribute to seafloor spreading. The cooling and solidification of this magma at the boundaries can create hydrothermal vents and mineral deposits that support unique ecosystems.
When a rock is heated it melts to form a liquid called what?
hot liquid that forms when rock melts is MAGMA
What kind of magma does Yellowstone have?
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
What forms when rock melts?
When rock melts, it forms magma. Magma is a molten mixture of rock-forming substances, gases, and water that is found beneath the Earth's surface. If the magma reaches the surface, it can then solidify to form igneous rocks.
What is the type of magma contain a lot of silica and water vapor is?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
What list places the magma What list places the magma types in order of decreasing?
basaltic,andesitic,rhyolitic

What rock that melts underneath earth?
The rock that melts underneath the Earth is called magma. Magma is formed from the melting of the Earth's mantle and can rise to the surface to form igneous rocks when it solidifies.
Will rhyolitic magmas erupt at lower temperatures than basaltic magmas?
Yes, rhyolitic magmas are several hundred °C colder than basaltic magmas. This is because the melting point of a rhyolitic magma is much lower than that of basaltic magma. Instead of heating up rhyolitic magma much above its melting point it will ascend and either crystallize in the Earth's interior as a pluton or erupt.

How can a sedimentary rock form into a igneous rock?
it melts into magma then cools and hardense
Can minerals crystallize out of magma when it melts?
Yes, minerals can crystalize when magma melts.
What are the three main types of magma and what factor determines these classifications?
The three main types of magma are basaltic magma, andesitic magma, and rhyolitic magma. They are classified according to their mineral composition. Basaltic magma is composed of SiO2 45-55 wt%, high in Fe, Mg, Ca, low in K, Na. Andesitic magma is composed of SiO2 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K. Rhyolitic magma is composed of SiO2 65-75%, low in Fe, Mg, Ca, high in K, Na.
