Layers of the Earth

During a geography class, Abigail and Mia were discussing the Earth's layers. They were particularly interested in the continental crust. What is the continental crust?

• the layer that extends from below the mantle to the center of the Earth

• the thinner crust that lies under the ocean

• the 5 physical properties of the layers of the Earth

• the thicker crust that is land

During a geography class, Mason and Elijah were discussing the oceanic crust. What is the best description of the oceanic crust?

• the layer that extends from below the mantle to the center of the Earth

• the thinner crust that lies under the ocean

• the 5 physical properties of the layers of the Earth

• the thicker crust that is land

During a geography class, Jackson, Aiden, and David were discussing the Earth's layers. They were trying to identify the characteristics of the outer core. What is the outer core?

• liquid layer of the Earth's core that lies beneath the mantle

• strong, lower part of the mantle

• the plastic layer of the mantle on which pieces of lithosphere move

• outermost, rigid layer of the Earth (the crust and the upper, rigid part of the mantle)

Henry and Nora are studying about the Earth's structure. They learned about the 'inner core'. What does 'inner core' refer to?

• the dense center of the Earth

• vibrations through the Earth that happen when there is an earthquake

• a machine that measures the times at which seismic waves arrive at different distances from an earthquake

• pieces of lithosphere that move around on top of the astenosphere
