layers can be defined by either their chemical or their rheological properties. Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
A random sample of 200 dancers were asked if they practice dancing 20 h or more per week. The results are shown in this table.
Based on the data in the table, select Correct or Incorrect for each statement.

The Earth's layers can be described chemically as the crust, mantle, and core, and physically as the lithosphere, asthenosphere, mesosphere, outer core, and inner core. Each layer is defined by distinct properties that influence geological processes. Understanding these layers is crucial for studying the Earth's structure and behavior.
