Interior of the Earth

Describe: The Lower Mantle?

2,900 km thick. Much of this layer is molten rock and is the warmest closest to the core, the upper portion of the mantle is called the Asthenosphere.

Describe: The Crust?

5-40 km, Solid, rocky, has continent and ocean basins. The continent is made of granite and the oceanic floor is basalt.

How does density change in relation to the depth below Earth's surface?

As depth increases the density of the Earth increases.

How does pressure change in relation to depth below Earth's surface?

As the depth increase the pressure increases.

How does temperature in relation to depth below Earth's surface?

As the depth increases temperature increases.

What is the detailed version of the layers?

Continental crust and oceanic crust, lithosphere, Asthenosphere, mantle, inner core, and outer core.

Which of the layers of the Earth are solid?

Crust and inner core.

What are the four main layers of the Earth?

Crust, mantle, outer core, and inner core.

Describe: The inner core?

Dense ball of solid metal hotter than the outer core and under so much pressure it doesn't melt.

Which layer of the Earth has the greatest density and pressure?

Inner core.

What are the outer core and inner core made out of?

Iron and nickle.

Describe: The outer core?

Molten metal that flows.

All other layers are made of?

Rocky material.

How would you best describe the properties of the Earth's mantle.

Solid but able to flow.

The mantle is?

Solid that flows.

The crust is?

Solid.

How does temperature, pressure, and density change as you go from crust to core?

Temperature pressure and density increase.

Describe: The Lithosphere?

The crust and the upper and most part of the mantle. This is a rigid solid layer.

Which layer of the Earth has the greatest temperature, pressure, and density?

The inner core.

How does the mantle interact with the crust?

The mantle convects and as it does it moves the plates which are part of the crust of the Earth.

Which layer of the Earth is most like the egg white of the hard boiled egg?

The mantle.

Does the outer core interact with the inner core?

The outer core heats the mantle during convection currents in the mantle.

Describe: The Asthenosphere?

The upper most part of the mantle. The rock is warm enough that it can bend like plastic.

What is the inner core and outer core made of?

They are both made of metal. And are also made of nickel and iron.

The outer core is?

liquid.

The inner core is?

solid.
