Which BEST describes the physical properties of the Earth's core?

• semi-molten

• water and organic substances

• a solid lower part and a liquid upper part

• contains volcanic, sedimentary and granitic rocks

Look at the diagram, which layer of the Earth is liquid?

• crust

• mantle

• outer core

• inner core

Based on the information in the table, what can you conclude about the density of the Earth's layers?

• The density of the layers decreases as the pressure increases

• The density of the layers increases as the temperature decreases

• The density increases in layers that are closer to the core of the Earth

• The density increases in layers that are closer to the surface of the Earth

What do the crust and the core have in common?

• they are both solid

• they both have the same temperature

• they both are under the same pressure

• they are both close to the center of the Earth

How is the crust different from the other layers of the Earth?

• It is hotter

• It is thinner

• It is mostly liquid

• It is under pressure

Which layer of the Earth is divided into plates that flow slowly due to convection currents?

• inner core

• outer core

• asthenosphere

• lithosphere

Which of the following best explains the formation of convection currents in the Earth's mantle?

• The Earth's mantle is heated uniformly, causing the material to rise and fall in a continuous cycle

• The heat from the Earth's core creates uneven temperatures in the mantle, leading to the movement of molten rock in circular patterns

• The gravitational pull of the Earth causes the mantle to rotate, generating convection currents in the molten rock

• Convection currents in the Earth's mantle are primarily caused by the magnetic forces between the Earth's core and the mantle, creating a circular flow of molten material
