Questions and Answers

Match the layers of the Earth with their descriptions:

Crust = The outermost layer of the Earth Inner Core = The solid innermost part of the Earth Outer Core = The liquid layer surrounding the inner core Lower Mantle = The layer below the upper mantle that is solid

Match the Earth layers with their characteristics:

Continental Crust = Thicker and less dense than oceanic crust Oceanic Crust = Thinner and more dense than continental crust Upper Mantle = Part of the mantle that is semi-solid and allows for movement Asthenosphere = The region of the upper mantle that behaves like a viscous fluid

Match the terms with their roles in Earth's geology:

Convection Currents = Circulatory movement in the mantle that drives plate tectonics Middle Mantle = Also known as the transition zone between upper and lower mantle Crust = The layer where we live and has the continents and oceans Lower Mantle = Layer responsible for the flow of molten material

Match the layers with their composition:

<p>Outer Core = Composed mainly of iron and nickel in liquid form Inner Core = Made up of solid iron and nickel Crust = Consists of rocks and minerals forming the land and ocean floors Asthenosphere = A viscous layer of partially melted rock in the upper mantle</p> Signup and view all the answers

Match the layers of the Earth with their temperatures:

<p>Inner Core = Can reach temperatures over 5,000 °C Outer Core = Temperatures ranging from 4,000 to 5,000 °C Lower Mantle = Temperatures around 3,000 °C Upper Mantle = Temperatures generally below 1,000 °C</p> Signup and view all the answers

Study Notes

Earth's Layers

Crust: The outermost layer of the Earth, composed of solid rock
- Continental Crust: Thicker, less dense, and older than oceanic crust. It makes up the continents
- Oceanic Crust: Thinner, denser, and younger than continental crust. It forms the ocean floor
Mantle: The thickest layer of the Earth, composed of hot, dense rock that flows slowly over time
- Upper Mantle: The uppermost layer of the mantle, includes the asthenosphere
- Middle Mantle: The middle layer of the mantle
- Lower Mantle: The deepest layer of the mantle, where the rock is very hot and under great pressure
Outer Core: A liquid layer of iron and nickel, generates Earth's magnetic field
Inner Core: A solid sphere of iron and nickel, extremely hot and under intense pressure
Asthenosphere: A partially-molten layer within the upper mantle, allowing tectonic plates to move
Convection Currents: Flows of heat within the mantle, caused by differences in temperature and density. These currents drive the movement of tectonic plates
