Earth's Layers
Layers of the Earth
| Question | Answer |
|---|---|
| Why is the inner core solid? | because of all the pressure from the other layers |
| What is the outer core made of? | liquid iron and nickel (liquid metals) |
| What is the crust made of? | solid rock and soil (The rock is mostly basalt and granite.) |
| What is the mantle made of? | very hot, molten rock (solid rock and magma) |
| What is the inner core made of? | solid iron and nickel (solid metals) |
| What layer supports the crust? | the mantle |
| What is the thinnest layer? | crust |
| What is the thickest layer? | mantle |
| What is the most dense layer? | inner core |
| What is the least dense layer? | crust |
| What is the coolest layer? | crust |
| What is the hottest layer? | inner core |
| What is the only liquid layer? | outer core |
| How are the outer and inner core alike? | They are both made of iron and nickel. |
| How are the outer and inner core different? | The inner core is solid, and the outer core is liquid. The inner core is more dense than the outer core. The inner core is hotter and under more pressure than the outer core. |
| What happens in the mantle that causes heat to rise toward the crust? | convection current |
| What is a convection current? | Warm, less dense material rises, and cool, more dense material sinks. This keeps happening over and over. It happens in the mantle. |
| What is density? | how tightly packed something is |
| What part of the Earth do we live on? | crust |
| What is the order of the layers starting from the surface? | crust, mantle, outer core, inner core |
| What are the differences between the oceanic crust and continental crust? | The oceanic is below the ocean, and the continental is below the land. The oceanic is more dense than the continental. The oceanic is thinner than the continental. |
| What are the two types of crust? | oceanic and continental |
| Which layer vibrates in place because of all the pressure put on it? | inner core |
| As you go deeper toward the inner core, what increases? | density, pressure, and temperature |
| What layer is made of solid and melted rock? | mantle |
