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.
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.
How can scientists learn about the mantle if we can't directly observe it?
Scientists study the mantle by analyzing seismic waves and volcanic activity. By measuring the speed and direction of seismic waves as they travel through the mantle, researchers can infer properties like temperature and composition. They also study the rocks and minerals brought up by volcanoes to gain insights into the composition and behavior of the mantle.
Is the subdivision of Earth's geosphere?
The geosphere is traditionally divided into three main layers: the crust, mantle, and core. These layers vary in composition, temperature, and physical properties. The crust is the outermost layer, followed by the mantle, and then the core.
What materials is in the mantle?
The mantle is composed mainly of solid rock, including silicate minerals such as olivine, pyroxene, and feldspar. It is divided into the upper mantle and lower mantle, with differences in temperature, pressure, and composition between the two regions. The mantle makes up the majority of Earth's volume and plays a crucial role in the movement of tectonic plates.

Where is the temperature of the mantle greater point a or point b?
The temperature of the mantle is greater at Point B than Point A. The temperature of the mantle is determined by its depth which is greater at Point B than Point A. The deeper the mantle the hotter and more pressurized it is and so the temperature at Point B will be greater than at Point A.Temperature can also be affected by other factors such as the composition of the mantle and the presence of radioactive elements. In this case since both points are in the same area and have similar composition the temperature will be determined by the depth.To summarize the temperature of the mantle is greater at Point B than Point A because it is deeper and thus more pressurized and hot.

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.
What is the average temperature of the mantle in Celsius?
Inner Mantle: The average temperature is about 3000ºC Outer Mantle: The average temperature is about 2200ºC
What is the composition of the outer mantle?
peridotite
What is the composition the mantle?
i dont now
What is the is the composition of the mantle?
it is dead bodies
Why is the mantle divided into 2 layers?
The mantle is divided into two layers, the upper mantle and the lower mantle, based on differences in temperature, pressure, and rock composition. The upper mantle is closer to the Earth's surface and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
