What type of rock do volcanoes make?
Volcanoes primarily produce igneous rocks when magma erupts and cools. If the magma cools and solidifies beneath the Earth's surface, it forms intrusive igneous rocks, such as granite. If the magma erupts onto the surface as lava and cools quickly, it forms extrusive igneous rocks, such as basalt. The specific type of rock depends on the composition of the magma and the cooling conditions.
What type of lava erupts from oceanic vents and quickly cools in the water?
That would be the result of a submarine volcano. Pillow lava is a common type of lava that submarine volcanoes produce.
What color is the lava of cinder shield volcanoes?
The lava of cinder cone volcanoes is typically dark in color, ranging from black to deep gray or brown due to its basaltic composition. When lava erupts, it can also appear reddish-orange when it is molten and flowing. As it cools and solidifies, it forms the characteristic cinder and ash that make up the volcano's structure.
What is is a molten rock that erupts from volcanos?
The molten rock that erupts from volcanoes is called lava. When magma, which is found beneath the Earth's surface, rises and reaches the surface during a volcanic eruption, it becomes lava. Once it cools and solidifies, it forms various types of volcanic rock. Lava can flow slowly or erupt explosively, depending on its composition and the gases it contains.
When a volcano erupts lava may flow onto the surface. What type of rock does the lava cooling form?
When lava cools on the surface, it forms igneous rock called basalt.
What forms when molten rock erupts onto Earths surface?
When molten rock erupts onto Earth's surface, it forms lava flows and igneous rock formations. The type of igneous rock formed depends on the composition of the magma and the speed of cooling. Each eruption can create unique landforms like volcanoes, lava plateaus, and volcanic islands.
What volcanoes form extensive fluid lava flow that erupts numerous times?
Shield volcanoes form extensive fluid lava flow that erupts numerous times.
What is molten before it erupts?
It is molten magma that erupts from volcanoes - commonly known as lava.
Does the lava in mount erebus melt the ice?
Yes, when it erupts -- and the lava cools quickly, forming a smooth lava solid. The heat from the crater forms in tall fumerals, which are unstable and can topple over.
What erupts from volcanoes along with lava?
Volcanoes can erupt ash, gas, and pumice in addition to or instead of lava.
When a volcano erupts what kind of rock is formed as the lava cools?
When a volcano erupts, the lava that cools and solidifies forms igneous rock. Depending on the cooling process, it can be classified as either extrusive igneous rock, such as basalt, which cools quickly on the surface, or intrusive igneous rock, like granite, which cools slowly beneath the surface. The mineral composition and texture of the rock are influenced by the chemical makeup of the lava and the cooling rate.
When Lava cools underwater what usually forms?
When lava cools underwater, it usually forms a type of igneous rock known as pillow lava. This occurs because the rapid cooling of lava in water causes it to solidify quickly and take on a rounded, pillow-like shape. Pillow lava formations are commonly found at mid-ocean ridges and undersea volcanoes.
