1 HOW IS THE EARTH STRUCTURED INTERNALLY?

2 10-50 km 700 km The Earth’s internal structure may be divided in a variety of ways, but, as a partial explanation for the distribution of the locations on the Earth’s surface at which internal energy is concentrate arises from fact that some internal layers behave more like “liquids” than “solids”, and others behave more like “solids” than “liquids”, this classification focusses on changes in those factors governing that “change in state” of Earth materials.

4 Crust km 700 km

5 Upper Mantle Crust km 700 km

6 Lower Mantle Upper Mantle Crust km 700 km

7 Outer Core Lower Mantle Upper Mantle Crust km 700 km

8 Outer Core Lower Mantle Upper Mantle Crust km 700 km Inner Core

9 10-50 km 700 km The change in state between “solids” and “liquids” is determined by the melting point of the material. Whether the Earth is solid or liquid will therefore depend on the interaction of three physical properties of the Earth at that point:
