how volcanic mountains are formed?
315971
Volcanic Mountains are formed when molten rock (magma) deep within the earth, erupts, and piles upon the surface. Magna is called lava when it breaks through the earth's crust. When the ash and lava cools, it builds a cone of rock.

The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual, which adds to the importance of trying to figure out when and how it happened.

Weegy: Igneous rocks are formed when lava or magma cools and then crystallizes. An element is a pure substance that can't be broken down into simpler substances by chemical or physical means.

Fold mountains are created where two or more of Earth's tectonic plates are pushed together, often at regions known as convergent plate boundaries and continental collision zones. The Cape Fold Mountains of South Africa, above, were created as the ancient Falklands Plateau crashed into the African plate.

The plates only move less than nine centimeters a year, so the mountains would have taken millions of years to form. Today the Alps are older mountains, and there are no longer any active volcanoes in the Alps, but they are still growing between a millimeter and a centimeter each year! 50 million years old.

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.

Mountains are made when Earth's crust is pushed up in big folds or forced up or down in blocks. Mountains form over the course of millions of years. ... There are fold, block, dome, and volcanic mountains. Mountains are jagged because they are constantly eroded by the weather, which wears the rocky surface away.

Igneous rocks form when magma or lava cools and solidifies. ... Metamorphic rocks form when existing rocks are changed by heat, pressure, or solutions.

Volcanic eruptions pull materials up from deep within the earth to form various volcanic landforms, such as lava domes, lava plateaus, fissure eruptions, craters and calderas.

Volcanic islands are formed by volcanic activity on the seabed, often near the boundaries of the tectonic plates that form Earth's crust. Where two plates pull apart, lava erupts to form an undersea ridge. Layers of lava build up until a ridge breaks the sea's surface to form an island.

There are three main places where volcanoes originate: Hot spots, Divergent plate boundaries (such as rifts and mid-ocean ridges), and. Convergent plate boundaries (subduction zones)

Igneous rocks are formed by the cooling and solidification of magma or lava. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may formwith or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Mountains are formed by slow but gigantic movements of the earth's crust (the outer layer of the Earth). The Earth's crust is made up of 6 huge slabs called plates, which fit together like a jigsaw puzzle. When two slabs of the earth's crust smash into each other the land can be pushed upwards, forming mountains.

Most mountains formed from Earth's tectonic plates smashing together. Below the ground, Earth's crust is made up of multiple tectonic plates. ... The result of these tectonic plates crumpling is huge slabs of rock being pushed up into the air.

Enjoy our igneous rock facts for kids. ... Igneous rock is formed when magma cools and solidifies, it may do this above or below the Earth's surface. Magma can be forced into rocks, blown out in volcanic explosions or forced to the surface as lava. The atoms and molecules of melted minerals are what make up magma.

Volcanoes are formed by eruptions of lava and ash when magma rises through cracks or weak-spots in the Earth's crust. A build up of pressure in the earth is released, by things such as a plate movement which forces molten rock to exploded into the air causing a volcanic eruption.
