What else can I help you with?
What causes the pressure to allow diamonds to form in the mantle?
The weight of the rocks in the crust and upper mantle.
Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
The mantle is made of what structural zones?
The mantle is composed of the upper mantle and the lower mantle. The upper mantle is known for its plasticity and convective movement, while the lower mantle is more rigid and is characterized by high-pressure conditions.
Why is the upper mantle solid?
the entire mantle is solid because the pressure is so great the rock are unable to melt.
What minerals are in the upper mantle?
The upper mantle is mainly composed of minerals such as olivine, pyroxene, and garnet. These minerals form under high temperature and pressure conditions in the Earth's interior, contributing to the solid composition of the upper mantle.
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
What causes the pressure to allow diamonds to form in the mantle?
The weight of the rocks in the crust and upper mantle.
What causes pressure to cause diamonds in the mantle?
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.
Is the upper or lower mantle dense?
No, it is hotter because it is closer to the inner core
What are three differences between the upper and lower mantle?
Temperature: The upper mantle is cooler than the lower mantle. Composition: The upper mantle is more silicate-rich and less dense compared to the lower mantle. Physical properties: The upper mantle is more rigid and brittle, while the lower mantle is more ductile and capable of flow.
Why is the lower mantle more rigid and dense then the asthenosphere in the upper mantle?
The lower mantle is more rigid and dense than the asthenosphere in the upper mantle because of higher pressure and temperature conditions. The increased pressure in the lower mantle prevents rocks from flowing as easily as in the asthenosphere. This leads to higher density and rigidity in the lower mantle region.
The mantle is made of what structural zones?
The mantle is composed of the upper mantle and the lower mantle. The upper mantle is known for its plasticity and convective movement, while the lower mantle is more rigid and is characterized by high-pressure conditions.
Why is the upper mantle solid?
the entire mantle is solid because the pressure is so great the rock are unable to melt.
What is the subdivision of the mantle?
The mantle is subdivided into the upper mantle and the lower mantle. The upper mantle is closer to the Earth's surface and consists of solid rock that can flow slowly over long periods of time. The lower mantle is located beneath the upper mantle and is more rigid due to higher pressure and temperature.
What minerals are in the upper mantle?
The upper mantle is mainly composed of minerals such as olivine, pyroxene, and garnet. These minerals form under high temperature and pressure conditions in the Earth's interior, contributing to the solid composition of the upper mantle.
Does the transition zone separate the lower mantle from the upper mantle?
Yes, the transition zone is a region in the Earth's mantle located between the upper and lower mantle. It is marked by changes in temperature, pressure, and mineral composition.
Is the mantle divided into two different parts?
Yes, the mantle is divided into the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more malleable, while the lower mantle is beneath the upper mantle and is more solid due to higher pressure and temperature.
