The earth
mantle,core, inner core, crust.
mantle:The mantle is the mostly solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84 percent of Earth's total volume.
Earth's crust is Earth's thick outer shell of rock, referring to less than 1% of Earth's radius and volume. It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle.[1] The lithosphere is broken into tectonic plates whose motion allows heat to escape the interior of the Earth into space.
Outer Core: The outer core, which is liquid, is about 1300 miles (2092 km) thick. Both the inner and outer cores consist primarily of iron and nickel and are extremely hot with temperatures ranging from 7200–9000℉ (4000–5000℃).
The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).
Energy in the home
stuff
-
payback time- Payback time is when someone has to take the consequences of what they have done in the past.
wires on cables
blue: .The neutral wire transfers electricity away from the appliance to avoid overloading. It is located at the circuit end to enable connection once electricity has flowed around the earth and live wires. It is highly unlikely that you will have an electric shock on contact with a blue wire.
brown: The brown wire has the function of carrying electricity to the appliance. If the brown wire is live and not connected to the earth or neutral wires there will be a risk of electrocution.
-
green/yellow: It is vital for safety as it connects the metal casing of the electrical appliance with the ground. This means that the current of the live wire cannot be directly transmitted to the casing.
