What are some similarities and differences between the mantle and the core?
the mantle is the part under the crust made up of nickel and iron moving about causing volcanoes whereas the core is solid because it is so tightly packed the minerals and metals have very constricted movement. the mantle is also the largest part of the Earth. the core has 2 sections the inner core and outer core
What is just below the Earth's crust?
The D" layer (pronounced D double prime layer) forms the base of the Earth's lower mantle. Below this lies the outer core. This boundary zone is marked by a seismic discontinuity known as the Gutenberg discontinuity.
How does the earth sustain life?
water, Oxygen, CO 2 Minerals
What are 2 types of minerals found in Earth's crust?
Two types of minerals found in Earth's crust are silicate minerals and nonsilicate minerals. Silicate minerals are the most abundant type and contain silicon and oxygen. Nonsilicate minerals do not contain silicon and oxygen in their chemical composition.
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.
What makes up earth's mantle?
The Earth's mantle is primarily composed of silicate minerals rich in magnesium and iron, such as olivine, pyroxene, and garnet. These minerals form a solid layer beneath the Earth's crust and extend to a depth of about 2,900 kilometers. The mantle experiences high temperatures and pressures, leading to convection currents that drive plate tectonics and other geological processes.
How many parts does the mantle have?
The mantle is typically divided into two parts: the upper mantle and the lower mantle. The upper mantle sits beneath the Earth's crust and extends to a depth of about 410 kilometers, while the lower mantle extends from 410 to 2,890 kilometers below the Earth's surface.

How is the earth' mantle like a peanut butter sandwich?
The earth's mantle is like a PP&J because of the core is colder. It is like the core is the peanut butter and the earth is jelly.
What sphere extends from earths core to earths crust?
The sphere that extends from Earth's core to Earth's crust is known as the mantle. It is a layer of solid rock that lies between the core and the crust, making up the majority of Earth's volume. The mantle is divided into the upper mantle and the lower mantle based on depth and composition.
What are the 2 layers of the mantle?
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
The middle layer of earth?
The middle layer of the Earth is known as the mantle. It is a zone of hot, solid rock that lies between the Earth's crust and core. The mantle plays a key role in driving the movement of tectonic plates and the convection currents that power the Earth's geological processes.
What is just below the Earth's crust?
The D" layer (pronounced D double prime layer) forms the base of the Earth's lower mantle. Below this lies the outer core. This boundary zone is marked by a seismic discontinuity known as the Gutenberg discontinuity.

What are the 3 main parts of the Earth from the center of the Earth out?
The three main parts of the Earth, starting from the center outward, are the inner core (solid metal), outer core (molten metal), and the mantle (semi-solid rock). These layers collectively make up the structure of the Earth known as the Earth's interior.
What are the two meanings of lithospere?
1. the solid portion of the earth ( distinguished from atmosphere , hydrosphere ). 2. the crust and upper mantle of the earth
