Earth’s Layers

Earth is divided into 4 main layers I predict one of the layers is ____ and I know this because _______.

Inner Core has temperatures and pressures so great that the metals are squeezed together and are not able to move. solid ball of solid nickel and iron.

Describe one characteristic of the inner core. One characteristic of the inner core is _____ and its similar to _______ because____________________. it’s hot the sun they’re both hot and round

Outer Core The outer core is made up of liquid iron and nickel. It is very dense (heavy).

Describe one characteristic of the outer core. One characteristic of the outer core is _____ and its similar to _______ because____________________.

Check For Understanding What’s the main difference between the earth’s inner core and its outer core?

The Mantle The mantle is the largest layer of the Earth. The mantle is made of hot, dense (heavy) rock divided into two sub layers: – Asthenosphere – Lithosphere

Describe one characteristic of the mantle. One characteristic of the mantle is _____ and its similar to _______ because____________________.

2 Sub Layers of the Mantle Lithosphere –c–cool, dense, and rigid upper part of the upper mantle – includes the solid outer section of Earth or crust Asthenosphere –P–Plastic like material that flows slowly like hot tar –T–The rigid lithosphere is thought to "float“ on top of the slowly flowing Asthenosphere

Describe one characteristic of the Lithosphere and one characteristic of the Athenoshpere. How does the Lithosphere and Athenosphere work together? The Lithosphere floats on top of the Athenosphere.

The Crust Not that kind !!!!!

Crust The crust is the layer that we live on so it is the most widely studied and understood.

In addition to rocks, what other natural formations can be found on the earth’s crust? Anther natural formation that can be found on the earth’s crust is _______ and I know this because ______.

2 Types of Crust Oceanic Continental The crust makes up 1% of the Earth. The crust of the Earth is broken into many pieces called plates.

Tectonic Plates

Predict…what are the main differences between oceanic and continental crust? The main differences between oceanic and continental crust are:

Oceanic Continental DifferencesOceanicContinental Depth3-5 miles5-25 miles Density Thinner but heavier Thicker but lighter Rock TypeBasalt (volcanic)Granite ElevationBelow Sea LevelAbove Sea Level Which one do you think is heavier? Which one do you think is higher? Which one do you think is thicker? Are they made of the same type of rock?

The Crust The Earth's Crust is very thin in comparison to the other three layers and brittle.

Describe one characteristic of the crust. One characteristic of the crust is _____ and its similar to _______ because____________________.

Check for Understanding What are the 4 main layers of the earth? What are they made of?

Predict….How far is it to the center of the earth? It is _______ miles to the center of the earth.

How Far To the Center? 4,025 miles!!!!

RADD: Provide at least one characteristic from each of the Earth’s four layers.. One characteristic of the Earth’s inner core is…
