Inside earth, Chapter 1
| Question | Answer |
|---|---|
| Lithosphere | The mantle and the crust together make the lithosphere which in Greek means "Stone" |
| Asthenosphere | A soft layer that flows slowly. |
| Outer Core | A layer of molten metal that surrounds the inner core and acts like a thick liquid. |
| Heat transfer | The movement energy when a warmer object's heat, transfers into a cooler object. |
| Raidiation | When heat is transferred into a cooler object. |
| Conduction | The process of heat transferring into another object. |
| Convection | The transfer between two bodies. |
| Convection current | A current in the fluid that represents Convection. |
| Density | The mass that makes it solid. |
| Mantle | A layer of hot rock. |
| Granite | A rock that has crystals, and it makes the continents of the earth. |
| Basalt | A dark rock that is found beneath the ocean crust. |
| Crust | A layer of rock that forms Earth’s outer skin. |
| pressure | The force pushing on a surface or area, and it increases as you go deeper and deeper. |
| Seismic wave | A ground vibration that helps geologists figure out how the planet is put together. |
| Continent | Seven great land masses surrounded by water. |
| Geologist | An expert in geology, the study of what the Earth is made of and how it was formed. |
| Rock | The material that forms the earth's hard surface. |
| Geology | The study of planet earth. |
| Constructive force | They shape the surface to make mountains and continents. |
| Destructive force | “Are those that slowly wear away mountains and eventually, every other feature on the surface” |
| Continental drift | A theory that continents can drift apart from one another and have done so in the past. |
| Pangaea | An extremely large landmass when all continents were connected together |
| Fossil | The imprint or hardened remains of a plant or animal that lived long ago. |
| Deep-ocean trench | A deep valley along the ocean floor beneath which oceanic crust slowly sinks toward the mantle. |
| Mid-ocean ridge | Giant undersea mountain range extending around the world like the seams of a baseball. |
| Sonar | A system that uses the reflection of underwater sound waves to detect objects. |
| Seafloor spreading | the idea that the middle of the ocean is spreading apart, moving very slowly in opposite directions. |
| Subduction | Process in which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent boundary. |
| Plate | A slab of Earth's lithosphere that can move around on the planet's surface. |
| Scientific theory | A well-tested concept that explains a wide range of observations about a particular scientific question. |
| Plate tectonics | The movement of the earth’s upper mantle and crust. |
| Fault | A break in Earth's lithosphere where one block of rock moves toward, away from, or past another. |
| Transform boundary | Two plates sliding horizontally past each other. |
| Divergent boundary | Place where two of Earth's tectonic plates are moving apart |
| Rift valley | A deep valley that forms when two plates drift apart |
| Convergent boundary | A boundary between lithosphere plates where the plates move toward one another and one plate is recycled into the mantle |
