Interior of Earth
Science
| Question | Answer |
|---|---|
| What are the two sources of Earth's internal heat energy? | Heat of formation and Radioactive Decay |
| What caused the Earth to become very hot during it's formation? | The constant bombardment of meteorites |
| What process occurs when a unstable molecule fives off heat and transforms into a stable molecule. | Radioactuve Decay |
| The Earth internal temperature is currently in equilibrium, which means that it is creating as much heat as it is losing. What process is creating new heat inside the Earth? | Radioactive decay is rreleasing heat within the Earth |
| Which of Earth's layers are separated based on Chemical Composition? | Crust, Mantle, and Core |
| Earthquake waves determine the different densities of Earth's layers. How does this work? | The earthquake waves are traveling at different speeds, showing the layers have different compositions. |
| What does chemical composition refer to? | How Earth's layers interact with each other |
| Meteorites are often used to infer the structure of Internal Earth. Why? | Meteorites and the Earth were both formed from the same Nebula. |
| What does the term Physical properties refer to? | How Earth's layers interact with each other |
| The Lithosphere floats on top of the Asthenosphere. How are these two layers separated? | The layers have different physical properties. |
| What indirect evidence is used to assume that the outer core is liquid? | Seismic waves decrease in speed when they reach the outer core |
| What process causes movement of Earth's tectonic plates? | They move when heat creates convection currents in Earth's mantle. |
| Which process best explains how heat moves inside the Earth | Heat from the outer core rises through the mesosphere |
| What is the inside of Earth still very hot and molten after 4.5 billion years? | Radioactive decay in the core creates heat |
| The correct order of Earth's chemical layers | Crust, mantle, core |
| Which of these scientific events help us understand the layers of the Earth? | Earthquakes |
| What causes the movement of the Earth's surface | Earth's plates move because of convection currents in the mantle |
| Explain how the tectonic plates move | Convection currents in the mantle push and pull pieces of Earth's crust. |
| What is Conduction | Occurs when atoms vibrate against one another |
| What does Radiation do | transfers heat using energy |
| What is convection | moves from one place to another through liquids |
