Hardned magma in a volcanoes pipe that remains when softer rock around it has worn away is called?
Hardened magma in a volcano's pipe that remains when softer rock around it has worn away is called the volcanic neck.
What rock does granite come from?
Granite is an intrusive igneous rock. It forms when magma from the earth's mantle forces its way up into the crust. Being intrusive means it doesn't reach the surface but remains enclosed in other rocks. This causes it to cool more slowly giving it larger crystal size. Erosion of the rock above and around it exposes it to the surface.
Contrast shield volcanoes and cinder-cones volcanoes?
Shield volcanoes are very wide and very long. They are formed by the slow, elongated flow of lava. Mauna Loa and Mauna Kea in Hawaii are two examples. Cinder cone volcanoes are smaller, more upright volcanoes formed by the fragments and remains of a magma vent. These rocks can be shiny like obsidian or occaisonally dull like the hole-filled black lava rocks.
How are volcanoes formed by convergent plate boundaries?
Where one convergent plate is subducted under another, the sinking slab (which is full of wet sediments and organic remains) is heated and some of it melts to form magmas which migrate upwards to form volcanoes on the edge of the overlying plate.
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.
Does an igneous form from remains of living organism?
No. Igneous rock forms from the cooling and solidification of molten rock.
Why are fossils found in sedimentary rock but not igneous rock?
Igneous rock forms from magma or lava. It would be unlikely an organism's remains would survive partially or intact upon exposure to such conditions.
Why do rock fossils form in sedimantry rock and not in igneous rock?
Fossils usually form when the remains of an organism are buried gently under sediments which later turn into stone. Intrusive igneous rocks form at depths within Earth where no life is found. Extrusive igneous (volcanic) rocks are so hot when they are deposited that any remains of organisms are usually incinerated. Fossils do occur in volcanic rocks, but very rarely.
Why do rock fossils form in sedimentary rock and not igneous rock?
Sedimentary rock can be made from sediments cemented together, or formed in the shape of remains of living things. Igneous rock is made from cooled magma, inside or outside the crust.
How did the Mayas civilization destroy?
No one really knows, it remains a mystery.. such as disease, war, famine, etc.
What is volcano islands?
Volcano Islands are the remains of dormant or still active volcanoes that have formed islands of land above the surface of the sea.

Why are fossils rarley found in igneous rocks?
Fossils are the remains or traces of animals or plants and are normally found in rocks which used to be sediments at the bottom of a body of water in which they lived or were swept into. None of these living organisms were able to live in molten magma which is what most igneous rocks used to be.
What is the good reason to destroy what remains of Hitler's bunker?
Thay destroyed it because they didn't want the evil place to become a shrine.
How did Victor destroy the female creature?
He tore up the half-completed project, placed the remains in a basket, and threw the basket into the sea.
