Concept Review Game - Layers of the Earth

Outer Core

• A variable that affects the state of matter of Earth's layers (thick layers of rock apply great forces to those layers buried below them, affecting the melting points of the buried rock.)

• The solid layer with plasticity in the upper mantle that is located just below the lithosphere; lithospheric plates float and move on this layer

• The outer shell of earth's core; surrounds the inner core and is made of liquid nickel and iron

• A variable that affects the state of matter of Earth's layers (layers of rock at greater depths from Earth's surface have more thermal energy.)

What is the main difference between the inner core and the outer core?

• Inner is a liquid, outer is a solid

• Inner is a solid, outer is a liquid

• Inner is solid rock, the outer is solid metal

• Inner is made of silica, outer is made of magma

The lithosphere contains all of the _____ AND part of the _____.

• mantle and outer core

• crust and mantle

• inner core and outer core

• inner core and mantle

What is meant by the term plasticity?

• A solid that is hot and fiery

• Something that is like a liquid

• A solid that is soft and flexible

• Something that is made of plastic

Earth's layers

• Distinct forms of matter known in everyday experience: solid, liquid, and gas.

• The divisions of the composition of Earth determined by either chemical composition or by the physical state of matter

• Characteristics that can be observed or measured; for example color, melting point, and conductivity

• The thin solid outermost layer of Earth; is made of less dense silicates and is either continental (landmasses) or oceanic (ocean floors)
