How would a rock that formed from lava cooling on the Earth's surface compare with a rock that formed from magma cooling deep in the Earth's crust?
The rock that formed from lava would have smaller crystals than the rock that formed from magma.
Is it true that the earth's crust is stationary?
The crust is formed on tectonic plates that are always moving because of the magma melting the rock under the surface causing them to move, so, in a way the Earth's crust is moving.
Mountains formed by magma that reaches the Earths surface are?
Mountains formed by magma that reaches the Earth's surface are called volcanoes.
Are intrusive rocks formed at Earth's surface?
No. Intrusive rocks form when liquid magma "squirts" into the crust and hardens. Igneous rocks that form at the earth's surface are called extrusive rocks.
How do intrusive and igneous rocks differ?
Intrusive rocks are formed from magma below the surface; extrusive rocks are formed from magma on the surface of Earth.
What boundary is formed when magma rises to the surface and new crust is formed?
divergent
How are oceanic crust formed at a divergent plate boundary?
The magma flows upward from the split in the crust caused by the boundary.
What type of rock is formed after volcanic magma cools?
If the magma cools on the surface of the crust, it is called extrusive igneous rock
What causes volcano to form at a diverging plate boundary?
When a huge piece of crust diverges (pulls apart), the crust becomes fractured and magma spills out on the surface.
How is the crust affected at divergent boundary?
Crust is being made there, from the upwelling of magma.
How is the earth's crust formed by a volcano?
Volcanoes bring liquid rock (magma) to the surface, which may have heavier elements from the lower crust and mantle.
How would a rock that formed from lava cooling on the Earth's surface compare with a rock that formed from magma cooling deep in the Earth's crust?
The rock that formed from lava would have smaller crystals than the rock that formed from magma.
What is the origin of all igneous rock?
All igneous rock is formed from solidified magma or lava.
Is granite formed from organisms?
No. Granite is an intrusive igneous rock, formed from the cooling, solidification, and crystalization of magma below the earth's crust/surface.
Is Mt Etna on a convergent divergent or transform plate boundary?
Mount Etna Was Formed By Destructive Plate Boundaries. This Is When One Crust Is Forced Under Another Crust. It Stands At The Convergent Boundary Where The African Crust Is Being Sub Ducted Beneath The Eurasian Crust. This Causes The Latter To Deform And Forces the Magma Up Into Weak Spots In The Earths Crust (mount Etna) When There Has Become To Much Of A Magma Build Up In The Mantle.
The opening in Earth's crust through which magma rises to the surface is known as the?
The opening in the earth crust which magma rise to the surface are Volcanoes
Is crust formed by cooled magma?
yes
