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.
How does the magma get above ground?
High pressures in the Earth’s crust pushes magma up cracks in the tectonic plates until it emerges above ground level.
When molten rock is below ground is called?
Magma
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.
Does magma cool above ground or beneath?
No. Molten rock under the surface is called magma. Molten rock above the surface is referred to as lava.
When magma erupts it is called?
lava
When magma erupts what is it called?
Lava.
Where does liquid rock or magma shoot out or erupt through the ground?
An place where molten rock erupts is called a volcano.
What is magma called when it erupts from a volcano?
It is called Lava.
Is magma called lava after it erupts?
Yes
What is the liquid rock in a volcano called?
Liquid or molten rock is called magma when it is below the ground and lava when it flows above the ground.
Why do rocks form?
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.
Molten rock under the ground?
yes there is its called the mantle its under the crust
When magma erupts from the volcano what is it called?
This is known as lava.
What is magma called after it has erupted?
It's called lava. Magma is formed in the magma chamber, then later when the volcano erupts, it turns to lava.
What is the melted rock in the earth called?
It is located in the mantle and is called Magma while in the ground and Lava when above ground.
