What melts to form rhyolitic magma?
Rhyolitic magma is typically formed from the melting of continental crust rocks such as granite and other felsic rocks. These rocks have high silica content, which contributes to the high viscosity of rhyolitic magma. Magma properties can also be influenced by other factors such as water content and temperature.
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 list places the magma What list places the magma types in order of decreasing?
basaltic,andesitic,rhyolitic
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.
What rocks are in a shield volcano?
Basaltic, Andersitic, and Rhyolitic
What is the opposite of basaltic?
The opposite of basaltic is rhyolitic. Basaltic rocks are formed from lava that is low in silica content, while rhyolitic rocks are formed from lava that is high in silica content.
What are three different types of lava?
Basaltic, andesitic and rhyolitic
Is pumice a foidolite rock?
Not necessarily. It is often andesitic or rhyolitic.
What type of lava does Yellowstone caldera have?
Both rhyolitic and basaltic lava flows have been found in the Yellowstone Caldera. There are alro large deposits of rhyolitic tuff.
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 element do scientist measure to classify magma?
Scientists measure the silica content, temperature, and viscosity of magma to classify it into different types, such as basaltic, andesitic, or rhyolitic. These properties help determine how explosive or effusive a volcano might be when the magma erupts.
Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
