The magma slowly cools over time into intrusive igneous rock. Later, often because the land is uplifted, the surrounding rock is eroded. Intrusive igneous rock, however, is often quite resistant to erosion, and so remains in place.

How do landforms form magma form and become exposed?
The magma slowly cools over time into intrusive igneous rock. Later, often because the land is uplifted, the surrounding rock is eroded. Intrusive igneous rock, however, is often quite resistant to erosion, and so remains in place.
After millions of years what landforms form from hardened magma in the pipe of an extinct volcano?
Volcanic neck
What forms when magma rises?
When magma rises, it can solidify to form igneous rocks like granite or basalt. If the magma reaches the Earth's surface, it can erupt as lava and form volcanic landforms such as volcanoes or volcanic islands.
In what order does magma become a rock?
Magma forms from heated rock--it cools--minerals form--when totally solidified it is a rock.
What happen to the magma after being pushed upward and exposed at the surface of the ocean floor?
The lava would form pillow basalts.
Why do igneous rocks tend to form long-lasting landforms?
Igneous rocks tend to form long-lasting landforms because they are typically hard and durable, resulting from the solidification of molten magma or lava. Their crystalline structure and resistance to weathering and erosion allow them to withstand environmental forces over extended periods. Additionally, many igneous formations, such as volcanic mountains and intrusive rock formations, are often uplifted and exposed, further contributing to their longevity in the landscape.
How obsidian rocks form?
They are formed when either a sedimentary rock or a metamorphic rock are exposed to high heat and turn into magma and then cool quickly.
What happens to the magma after being pushed upward and exposed at the surface of the ocean floor?
When magma reaches the surface of the ocean floor, it cools and solidifies to form igneous rocks like basalt. The rapid cooling of magma at the surface allows for the formation of characteristic features like pillow basalts and seafloor spreading ridges. Over time, these rocks may become buried, eroded, or further altered by geologic processes.
In order to form magma what must happen to sedimentary metamorphic or igneous rocks?
In order to form magma, sedimentary, metamorphic, or igneous rocks must be exposed to high temperatures and pressures deep within the Earth's crust. This process causes the rocks to partially melt, forming molten rock called magma.
What forms when magma hardens in a volcane pipe and is latter exposed?
A volcanic plug. Frequently when glacially eroded these plugs form crag and tail feature.
Magma can change form when?
Magma can change form when it cools and solidifies to become igneous rock. This process typically occurs underground, allowing the magma to cool slowly and crystallize into different types of igneous rocks such as granite or basalt.
What is three ores they form within cooling magma?
Pews such as chromium,nickel,and lead, pb, ores form within cooling
