Front

What are the two main components of the lithosphere?

Back

The lithosphere consists of the upper mantle and the crust.

Front

What is a key feature of Earth's outer core?

Back

The outer core is liquid and lies below the mantle.

Front

What property do the layers of a clay model of Earth share with the real Earth?

Back

The model will have layers that are in the same positions as the real Earth.

Front

How does density change when moving from Earth's crust to the outer core?

Back

Density changes from least dense in the crust to most dense in the outer core.

Front

What material best represents the asthenosphere in a model?

Back

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, consisting of solid rock.

Front

What is the mantle?

Back

The mantle is the layer of the Earth between the crust and the outer core, composed of semi-solid rock.

Front

What is the outer core?

Back

The outer core is a liquid layer composed mainly of iron and nickel, located beneath the mantle.

Front

What is the inner core?

Back

The inner core is the solid innermost layer of the Earth, composed primarily of iron and nickel.

Front

What is plasticity in the context of Earth's layers?

Back

Plasticity refers to the ability of the mantle to flow slowly over time, allowing tectonic plates to move.
