|---|---|---|---|---|---|
| What is water vapor? | A gas.
🗑
|
||||
| Seismic waves | What earthquakes produce when they occur.
🗑
|
||||
| Rock samples | The rocks give geologists clues about Earth's structure and conditions deep inside Earth.
🗑
|
||||
| What are the Earth's layers from outside to inside? | Crust, mantle, and core.
🗑
|
||||
| Radiation | The transfer of energy that is carried in rays like light.
🗑
|
||||
| Conduction | Heat transfer between materials that are touching.
🗑
|
||||
| Convection | Heat transfer by the movement of a fluid.
🗑
|
||||
| What is the thickest layer of the Earth? | The mantle.
🗑
|
||||
| What part of the Earth's layers contain the most mass? | The mantle.
🗑
|
||||
| What is Earth's inner core made up of? | Iron and nickel.
🗑
|
||||
| What part of Earth contains plates. | The lithosphere.
🗑
|
||||
| What is the theory of plate tectonics? | Earth's plates are in slow, constant motion, driven by convection currents in the mantle.
🗑
|
||||
| What produces Earth's magnetic field? | Movements in the liquid in the outer core.
🗑
|
||||
| What are the four main spheres, and how do they interact with each other. | The A, G, H, and B are the main spheres. The A contains Earth's weather. When it rains or snows, the G gets affected by changing land forms. The H can get flooded by the water and snow. This would flood habitats for the B and make food hard to find.
🗑
|
||||
| What is the difference between oceanic and continental crust? | The oceanic crust is thin and has a dark color. The Continental crust is thick with and has a light color.
🗑
|
||||
| What layer is made up of crust and partly mantle material? | The lithosphere.
🗑
|
||||
| Where is the asthenosphere located? | Below the lithosphere.
🗑
|
||||
| Describe how pressure increases as the depth increases. | Because of the weight of the rock above, pressure inside Earth increases with depth.
🗑
|
||||
| What layer has the most pressure on it? | The core.
🗑
|
||||
| What are some differences and similarities, between the inner core and the outer core? | The inner core is a ball. The outer core is a layer. They are both squeezed with pressure. The inner core is solid metal. The outer core is liquid metal.
🗑
|
||||
| What are some differences between conduction, convection, and radiation? | Radiation is transfers energy, while conduction and convection transfer heat. Conduction transfers heat with materials touching. Convection transfers heat with the movement of fluid.
🗑
|
||||
| How is heat transferred inside Earth through convection currents | Heat from the core and the mantle itself.
🗑
|
||||
| What causes tectonic plates to move? | Convection currents.
🗑
