What is the liquid rock called when it is inside the Earth?

Magma
Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma.

What is a mountain that spits out molten rock and ash called?

volcano
A volcano on Earth is a vent or fissure in the planet’s crust through which lava, ash, rock and gases erupt. A volcano is also a mountain formed by the accumulation of these eruptive products.

What type of volcano erupts with ash?

Vulcanian
The Vulcanian type, named for Vulcano Island near Stromboli, generally involves moderate explosions of gas laden with volcanic ash. This mixture forms dark, turbulent eruption clouds that rapidly ascend and expand in convoluted shapes.

What type of rock is made from liquid rock and cooled when a volcano erupts?

Igneous rocks
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.

What is the inside of the Earth called?

The solid, outer layer is called the crust. Below the crust lies a layer of very hot, almost solid rock called the mantle. Beneath the mantle lies the core. The outer core is a liquid mix of iron and nickel, but the inner core is solid metal.

What is the name of the liquid inside a volcano?

When geologists refer to magma, they’re talking about molten rock that’s still trapped underground. If this molten rock makes it to the surface and keeps flowing like a liquid, it’s called lava. Magmas vary in their chemical composition, which gives them—and the volcanoes that contain them—different properties.

Are all mountains formed by volcanoes yes or no explain your answer?

Volcanoes may be hill to mountain size. However, not all hills and mountains are volcanoes. Some are tectonic features, constructed by mountain building , which often happens at plate boundaries, just like volcanism. Others are erosional features, leftovers from earlier tectonic mountains.

How is ash formed?

Volcanic ash is formed during explosive volcanic eruptions. Expanding gas also shreds magma and blasts it into the air, where it solidifies into fragments of volcanic rock and glass. Once in the air, hot ash and gas rise quickly to form a towering eruption column, often more than 30,000 feet high.

What type of volcanoes are formed over many years and can grow to mountains of over 8000 feet tall?

Composite volcanoes – These volcanoes are also shaped like a cone, but are formed from layers of lava over many years. They can grow into huge mountains over 8,000 feet tall from their base.

What kind of rocks are found in volcanic mountains?

When magma does reach the surface during a volcanic eruption, the rocks that form there are called lavas or volcanic rocks. The basic classification is the same as for plutonic rocks: with increasing silica content, they include: basalt, andesites, dacites, rhyolite, pumice and obsidian.

What type of rock is formed by weathering and erosion?

Sedimentary rocks
Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
