In how many layers is the Earth divided?
Should humans colonize other planets in the solar system to avoid the potential dangers of climate change on Earth?
Checkin: Draw/write - What do you think are the benefits of trying new things?
The Earth is made up of several layers, including the inner core, outer core, mantle, and crust. The inner core is a solid ball of iron and nickel, while the outer core is a liquid. The mantle is made up of hot, solid rock and the crust is the solid outer layer where we live.
What's Inside the Earth?
Crust: The outermost layer of Earth's surface, composed of solid rock and minerals. Mantle: The layer of Earth just beneath the crust, composed of hot, solid rock. Core: The innermost layer of Earth, composed of a hot, dense metal center and a surrounding liquid metal layer.
What do you think is the composition of the Earth's inner core?
- Iron and Nickel
- Rock and Metal
- Silicon and Oxygen
- Magnesium and Sulphur
The temperature of the Earth's inner core is estimated to be around 5,000 to 7,000 degrees Celsius, hotter than the surface of the Sun! The Earth's inner core is believed to be made of solid iron and nickel, surrounded by a liquid outer core. The Earth's core is believed to be about 3,500 kilometers thick, about a third of the Earth's total radius.
