How does magma form ay divergent boundaries?
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.
What happens when magma rises to the surface?
It cools and solidifies into a sedimentary rock.
What force pushes a heated rock up?
Hot molten rock rises due to its lesser density and therefore results in a more buoyant material. In addition, it is part of a convection cell where hot rock rises and cold dives into the earth's interior.
Does heated magma rise or sink?
When magma is being heated it rises. When it is cooled, it sinks.
When metamorphic rock changes to magma the magma rises and cools to become?
A metamorphic rock is formed by the elements, minor heat, and compression. When the metamorphic rock is melted by magma, this would indicate that the metamorphic rock is under the surface of the earth. If it rises and cools again you will have an extrusive igneous rock. In a lot of cases, this is metamorphic rock on the surface under the influence of lava. This would change the composition and it would not longer be metamorphic, but rather igneous.
What type of monadnock mountain?
A monadnock or inselberg is an isolated rock hill, knob, ridge, or small mountain that rises abruptly from a gently sloping or virtually level
Isolated hill made of hard rock?
Knob
On which continent will you find Uluru?
Uluru, formerly known by its European name of Ayers Rock, is in the continent of Australia. It is a huge sandstone monolith or, more correctly, inselberg, in central Australia. It is a bald knob of rock which rises 348m above the surrounding flat plains, and which has a circumference of about 9.4 km.
What is an inselberg?
An inselberg is an isolated hill or mountain that rises abruptly from a flat surrounding plain, typically composed of hard rock that is more resistant to weathering and erosion than the surrounding rock. Inselbergs are commonly found in arid and semi-arid regions.
When melted rock is formed it always?
Rises
If the temperature of rock rises above the melting point of the minerals the rock is composed of?
The rock will melt.
How does magma form ay divergent boundaries?
Hot mantle rock rises to fill rift zones. When rock rises, a decrease in pressure causes hot mantle rock to melt and form magma.
What is it called when a rock layer rises?
uplift, i think
What happens when temperatures of rock rises above its melting point?
The rock melts to form magma.
How does a igneous rock turn into a igneous rock?
An igneous rock is formed when magma rises through the earth's crust and cools.
How does igneous rock turns into a igneous rock?
An igneous rock is formed when magma rises through the earth's crust and cools.
What kind of mountain is formed when molten rock rises?
a vulcano
