Convection
Storyboard Text
- There are 4 main layers, the crust, mantle, outer core, and inner core
- Today, we will be learning about convection. we will be going into the volcano that will give us access to see the Earth's layer
- Wow that's so cool, I'm so excited. How many layers of the Earth are there?
- First up is the crust. it is the thinnest layer of the Earth. the crust is broken up into 2 section. The continental crust and oceanic crust
- Tectonic plates are pieces of the Earth's crust
- What are tectonic plates?
- Tectonic plates are massive slabs of rocks that are ALL over the Earth
- Below the crust is the mantle, the largest layer of the Earth. It is also where convection current occur
- Heat rises from deep inside the mantle, while the cooler material in the mantle sinks
- When a substance is hot, particles moves faster than it would when it's cold . Hot substance are also denser than cold substance
- wait so why does heat rise and cooler air sinks?
- because of a process call convection
- Lastly is the Earth's core. It is the heat source of the Earth, The heat comes from the core, which is then transferred into the mantle where convection occur
- The core can be up to 9000 degrees F
- How hot is the core?
- That will conclude the trip. hopefully you guys know a bit more about convection now
- No problem kids!
- Thank you for explaining what convection is!
