I know it is composed of 4 layers: 3 solid and 1 liquid.

I learned that density can be layered from most dense to least dense.

The outer core is a liquid layer made up of iron and nickel

We know that convention currents are in the mantle. We know that the outer core is like wax. we know the radiation from the core takes a long time to get to the surface.

What causes some of the layers of Earth not to be livable besides the temperatures?

# data[].attributes.body
I know that the earth has four layers, the crust, mantle, the outer core, and inner core. And the layers on the innermost part of the earth are more dense than the layers on the outermost part.

What I know.

I know that the Earth is made up of multiple layers, including;

The Crust - The crust is the surface of the Earth, or the outermost layer, it is the thinnest layer of the Earth. The crust's temperature is possibly around 22 Celsius, or 71 degrees Fahrenheit. Though, the temperature increases further down. The crust is solid, the oceanic crust consists of Fe, O, Si, Mg, and Al.

The Mantle - Now the mantle is located between the crust and the outer core, and it is the largest layer. The mantle's temperature is potentially around 230 Celsius or even a big jump with 1, 400 Celsius, but who truly knows? Now the mantle is in the state of liquid AND solid, it consists of Fe, O, Si, Mg, Ai. And, the mantle contains convection currents.

(Convection currents are movements within Earth's mantle. Think of a lava lamp, if not plugged in, it remains cool. But, once the lamp is plugged in, it begins to heat up which leads to the cooler substances heating and rising. Convection currents in Earth's mantle happen because hot rock rises, heated by Earth's core. Moving in two different directions, going sideways, it begins to lose heat eventually the much cooler, less denser, rock sinks back down).

The Outer Core - The Outer core is the fluid layer above the inner core. The motion of the liquid creates the Earth's magnetic field. The outer core consists of Fe, Ni, S, O. And its temperature could be around 4, 000 - 6, 000 Celsius, or 7, 000 - 10, 000 Fahrenheit.

And last but not least, The Inner Core - The inner core is the middle of the Earth, made up of solid components. The inner core consists of Fe, Ni. It is also the HOTTEST layer, its temperature could be around 5, 000 - 6, 000 Celsius, or 9, 000 - 10, 000 Fahrenheit.

As a plus, we have conduction.

(Conduction is thermal transfer. Like having a hot cup of tea or a boiling pot of water. Adding a cold spoon to either causes the heat from the already heated liquid to transfer to the spoon. Even electricity is transmitted). Now granted, I may know a bit more than that, but my hands hurt and so does my brain.

What I want to know.

I would like to know how exactly Earth became..well, Earth?

How did Earth begin? Just a floating rock? Why are some layers survivable but others not so much?

# data[].attributes.body
I know that the earth has layers like an onion, and they all have different purposes

# data[].attributes.body
What I've learned.

I have learned a plethora of things in science, especially Earth science. I have learned how convection currents are like lava lamps or how density affects cold water and hot water.

I've learned about conduction and how heat transfers to something in short timing.

I've even had the pleasure of learning about fossils and the age-old mammals that once roamed. I've learned a lot, from rocks to liquid, from Earth's surface to deep within the water.

That volancos are a lot older than I thought they were

# data[].attributes.body
I want to know where the first volcano was formed

# data[].attributes.body
I learned how the movement of the platonics have happen and how the rock is so old, its because it was born so long ago and continues today. plus 170 million years is a long time.

# data[].attributes.body
1. One thing new that I learned was that the ridges are being pulled by the trenches. Then, the trenches are pushing the plate that is being pulled under the other plate (or subduction).

2. I also learned that the age of the rock in the trench is 175 million years old.

3. Another thing I learned was that the reason there are no earthquakes at the trench is because the rock is mud and acts like a lubricant.

Subduction is how the Mariana trench was formed. The earths crust has plates that can float on the molten rock or magma.

# data[].attributes.body
well I learned that some volcanoes have mud inside of them instead of magma

# data[].attributes.body
I learned that it is one of the deepest parts of the ocean and it is formed from magma and there it mud inside of it .

What I have learned about the Mariana Trench.

The Mariana Trench is a convergent plate boundary. The Mariana Trench is actually really old, with some of the oldest seafloor. There is mud at the bottom of the Mariana Trench, made up of certain sediments.
