Diamonds are formed deep within the Earth's mantle under high pressure and temperature conditions. Carbon atoms are arranged in a crystal lattice structure, creating the hard and transparent gemstone we know as a diamond. Over millions of years, these diamonds are brought closer to the Earth's surface through volcanic eruptions, where they can be mined.

Why are diamonds made by people not considered minerals?
Diamonds made by people are not considered minerals because they are synthetic and do not occur naturally in the Earth's crust. To be classified as a mineral, a substance must be naturally occurring and have a specific chemical composition and crystalline structure. Since synthetic diamonds are man-made and not formed through natural geological processes, they do not meet the criteria to be classified as minerals.
Where in the earths crust must a mineral occur?
A mineral must occur in the Earth's crust, which is the outermost layer of the Earth. This layer extends from the surface down to about 50 kilometers deep. Minerals are typically formed through geological processes in the crust, making this layer the most common place to find them.
What of earths layer is formed by diamond?
Diamonds are typically formed in the Earth's mantle, which is the layer located between the crust and the core. They are formed under high pressure and temperature conditions deep within the mantle, around 150-200 kilometers below the surface. Through processes involving carbon atoms being subjected to extreme heat and pressure, diamonds gradually form over millions of years.
What is the name of the long deep valleys that are formed by the movement of Earths crust?
rift valleys
Compared to earths continental crust earths oceanic crust is?
Earth's oceanic crust is thinner, denser, and younger than Earth's continental crust. It is primarily composed of basaltic rock, whereas continental crust is made up of less dense granitic rock. Oceanic crust is constantly being formed at mid-ocean ridges and destroyed at subduction zones.
What is formed by heat and pressure in the earths crust?
Many elements and materials which could not have been produced any other way (like diamonds).
What is formed through the uplift under the earths crust?
crust
Most of the actinides occur naturally in the earths crust?
no they do not
Which of earths layers is formed by volcanic activity?
Crust
Are genuine diamond the same as a real diamond?
Yes, "genuine" and "real" diamonds typically refer to diamonds that are naturally formed in the Earth's crust. Synthetic or lab-created diamonds are not considered genuine or real in the traditional sense, even though they have the same chemical composition as natural diamonds.
Which of these is formed when plates of earths crust bend and crack?
a fault
Why are diamonds made by people not considered minerals?
Diamonds made by people are not considered minerals because they are synthetic and do not occur naturally in the Earth's crust. To be classified as a mineral, a substance must be naturally occurring and have a specific chemical composition and crystalline structure. Since synthetic diamonds are man-made and not formed through natural geological processes, they do not meet the criteria to be classified as minerals.
In which part of the earth are diamonds most often formed?
the mantle and the crust, in the lithosphere.
What characteristic do diamonds share with other minerals?
One characteristic diamonds share with other minerals is that they are naturally occurring and formed in the Earth's crust. Additionally, like other minerals, diamonds have a specific chemical composition and crystalline structure that defines their unique properties.
Why do you think geologists use drills bits covered with small diamonds to drill earths crusts?
Because they have to get through the minerals and rocks in the earths crust.
Is diamond natural or man-made?
Diamonds are a naturally occurring substance found deep in the earth's crust.
What forms valcanoes?
most volcanoes are formed from a hot spot in the earths crust.
