Where does magma form?
Magma is the term applied to molten rock beneath the surface of the earth. It is formed when hot (very hot) rocks experience a drop in surrounding pressure, or when subducted wet lithosphere is introduced into the mantle. When it "breaks out" onto the surface of the earth, we call it lava. A link can be found below.
What is the term that describes all of the water o earths surface?
Salt water (in the form of oceans, seas and straits).
What is liquid rock?
Ah, liquid rock is a fascinating thing, my friend. It's just like when you're painting with warm, flowing colors on your canvas. When rock deep beneath the Earth's surface gets so hot that it melts, it turns into liquid rock, also known as magma. This magma can eventually make its way to the surface and flow out as lava, creating beautiful landscapes and new land for all of us to enjoy.
How does air help shape the Earth?
the wind causes erosion, carrying the soil to any place on earth, dropping it onto any surface, thus controlling the earth's surface.
Oceans make up the earths layer called the?
Oceans are part of the hydrosphere. The hydrosphere is all the water on Earth at any given moment.
Lava is a type of magma but not all magma is lava?
Magma is molten rock beneath the Earth's surface, while lava is magma that reaches the surface through a volcano or fissure. So, while all lava was once magma, not all magma will reach the surface as lava.
Does all magma come from the earths core?
No, not all magma comes from the Earth's core. Magma can also originate from the mantle, which is the layer beneath the Earth's crust. The heat and pressure from the mantle can cause rocks to melt and form magma, which can then rise to the surface as volcanic eruptions.
Is. magma is melt rock that has come to the surface?
No! First of all, magma is below the surface and it is molten material.
What is melted rock that has been exposed to earths surface?
'Magma' while it is still in or below the Earth's surface and when it reaches or flows out on the Earth's surface it is called 'lava'. Magma from the 'magma' chamber can form a 'lava lake' at the surface and the lake can drain down the volcano in 'lava tubes' to form 'lava flows' or 'pillow lavas' if the lava tubes drain into the sea.
Does all magma surface?
No. Along its path to the surface, most magma is stopped short by gradual cooling and solidification at a point below the surface.
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Does all magma come from earths core?
Yes it does because where else would it come from.
Is all igneous rock formed from lava that cooled on Earths surface?
No, not all igneous rock is formed from lava that cooled on Earth's surface. Some igneous rocks are formed from magma that cooled below the surface, and these are called intrusive igneous rocks. These rocks cool more slowly than lava, allowing for larger mineral crystals to form.
What do all volcano's share?
Pocket of magma beneath the surface
Do all volcanoes have a pocket of magma beneath the surface?
yes
Do all volcanoes have pocket of magma beneath the surface?
yes
Are there any gases in the earths crust?
All of the atmospheric gases can be found trapped in magma and solidified rock.
