Friday, April 26, 2019 Objective: YWBAT describe the physical properties of the layers of the Earth. Drill: The composition of the core is probably similar throughout. Why, then, is part of the core liquid and the rest solid? Homework Play Outside!!

Answer The inner core is extremely hot but the high pressure keeps the material in a solid state. The outer core has less pressure so the iron can stay in a liquid state.

Did you know…? The deepest hole ever drilled was 12,226 feet deep. It was difficult to drill deeper because liquid rock filled the hole.

Today’s Activities Drill Journey to the Center of the Earth – Add Physical Layers of the Earth and facts Conclusion

Closure True or False: The asthenosphere is a layer of slowly flowing rock beneath the lithosphere.

Closure Answer True
