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).
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.
Explain how the presence of silica and water in magma increases the chances of an explosive eruption?
The higher the silica content of the magma, the more explosive the eruption. Magma enriched in silica has a higher viscosity (resistance to flow). Pressures are more likely to build up behind the thicker, high silica content magma and result in potentially more explosive eruptions.
Is all igneous rock formed from lava that cooled on Earths surface?
No the rock may have cooled underground but yes all igneous rock was once magma.
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.
What is true about all plutons?
they form above earths surface (THIS ANSWER IS NOT CORRECT) They Form BELOW earths surface(:
Does all magma come from earths core?
Yes it does because where else would it come from.
Does all magma come from the earths core?
Yes it does because where else would it come from.
Do all volcanoes have pocket of magma beneath the surface?
yes
Do all volcanoes have a pocket of magma beneath the surface?
yes
What do all volcano's share?
Pocket of magma beneath the surface
What do you call all of the water on earths surface?
hyrdosphere
