What type of rock is formed when magma undergoes crystallization above ground?
Extrusive igneous rock is formed from the crystallization of magma (lava) above ground.
Where does Igneous rock form below or above?
Igneous rocks are formed from the cooling of lava/magma. (Lava is magma that has been moved from beneath the Earth's surface to above.) They can be formed above or below the Earth's surface- when formed above is called 'Extrusive Igneous rock' and when formed below is 'Intrusive Igneous rock'. When a rock is extrusive, it forms small crystals. When it is intrusive, it causes large crystals to form.
What is one cause of volcanic activity and igneous rock formation?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
What is the hot liquid that forms when a rock partially or completely melts?
Liquid rock is called magma when it is underground and lava when it is above ground.
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 type of rock is formed when magma undergoes crystallization above ground?
Extrusive igneous rock is formed from the crystallization of magma (lava) above ground.
Is all igneous rock formed by volcanoes?
No. Igneous rock is simply the solid substance left when magma or lava hardens, above ground or below ground.
Igneous rock forms from?
Plutonic rock is formed from magma in the Earth's crust. Volcanic rocks form from lava above ground.
How is ignius rock formed?
it is formed either underground or above ground. it is formed underground when hot magma is trapped and cools slowly, when it has cooled down it has then become igneous rock but on top of the ground the lava cools much quicker then what it does below the ground
What is a synomyn for lava?
A "synonym" for lava would be "molten rock". Lava is above ground. Magma is below ground.
What is molten rock above ground called?
lava
What distinguishes magma from lava?
magma is molten rock that is still underground and lava is molten rock that is above ground
What name is given to molten rock above ground?
lava
What do you call a molten rock?
Molten rock is called magma when it is below ground and lava when it is above ground.
When is igneous rock formed?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
What is melted rock below ground called?
The melted rock below the crust is magma. Above ground it is lava.
What is the term for molten rock?
Magma, or lava, which is magma above ground.
