no it does not not at all it takes about well the longest would ever be 10 to 20 years

If magma crystallizes before it reaches earths surface it will form a what igneous rock?
It will for an intrusive igneous rock. They usually take longer to cool and have more coarse grains.

How is old is petrified wood?
Practically all petrifaction takes a million years or more. However, formation by silicates can take less than 50,000 years. Some examples are estimated to be between 50 to 250 million years old.
As compared to mafic igneous rocks do all felsic igneous rocks cool and solidify more slowly?
No. Whether igneous rocks cool quickly or slowly is more dependent on whether the rock is intrusive or extrusive than whether it is mafic or felsic. Because it is so viscous it is often difficult for felsic magma to erupt, and so it is more likely to be intrusive and thus cool slowly. When felsic magma is involved in an eruption, it often erupts explosively. Some of the molten rock ejected cools extremely rapidly, forming volcanic glass.
Why are Europe and North America further apart today than they were 65 million years ago?
The mid-Atlantic ridge has been constantly producing more new land as magma is pushed up into the crack and hardens. This pushes apart the North American and Eurasian tectonic plates.
How is ellberton granite firmed?
Elberton granite began 325 million years ago as a large mass of magma or molten rock. The magma rose upward and came to rest about nine miles beneath Elberton. There it cooled very slowly -- taking more than a million years -- and solidified into granite. That was more than 300 million years ago. Since then, the granite has been pushed upward, and the land above it has been removed by erosion.
Why would lava cool more quickly then magma?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
How can mantle flow because its made of hot liquid magma?
Magma in the mantle moves in a current called a convection current. A convection current is a circular flow of a substance in which a hot substance rises, cools, sinks, gets hot again, and repeats. In this way, magma in the mantle flows in currents of more hot or more cool magma.
What time references best fits the concept of geologic time a dozen years a hundred years a thousand years a million or more years?
a million or more years
How does magma or lava cool down after erupting?
Anything that is warmer than its surroundings will transfer heat to them and cool down in the process. Lava from a volcano transfers heat to the air, which then carries it away. Underground magma transfers heat to the surrounding rock. Since rock is a poor conductor of heat the magma will cool much more slowly than if it were at the surface.
When the mantle is heated the magma rises because?
When it is heated it becomes less dense (i.e. lighter). The more dense (i.e. heavier) magma sinks while the less dense magma rises to the top. It will eventually cool again causing a convection current within the mantle.
What is a cool fact about pi?
Pi has more than a million digits to it. Its 3.14159...etc
Would geologic time be more like 12 years 100 years 1000 years or 1 million years?
Geologic time is very long, so a million or more years is the best choice.
How old is the Nile River?
As old as history itself, at least a few million years.
What best fits the concept of geologic time a dozen years a thousand years a hundred years or a million or more years?
Millions of million years, Billions of years, (Aeon).
How old was the Sun a million years ago?
The sun was roughly 4.6 billion years old a million years ago. The margin for error on the estimated age of the sun is more than a million years.
