Hello! My name is Ella and I will be your tour guide today for our trip around the Earth!
The crust is the outermost layer, the top, in the Earth's makeup. There are two different crusts, the oceanic, and continental. It is 5-70 km thick but is still the thinnest layer. The temperature range in the crust is 200-400 degrees Celsius. The crust has the lowest pressure of 4.01 atmosphere. It is made up of rock and is the only layer with oceans and large bodies of water.
The first layer of the Earth is called the crust. We live on this layer, which you probably already know.
Next up is the upper mantle. The upper mantle is the second outermost layer of Earth. It is about 640 km thick. The temperatures range from 1600-4000 degrees Fahrenheit.
The pressure of the upper mantle is 240,00 atmospheres. This layer is made up of rocks that have somewhat melted. IT is not a sold not a liquid, like the consistency of silly putty.
The pressure of the lower mantle is 240,000 atmospheres. This layer is similar to the upper mantle, made up of rocks and other things that have melted but are not fully liquid yet.
The lower mantle is the third layer of Earth from outside in. The lower mantle is 1160 km. The lower mantles temperature ranges from 1600-400 degrees Fahrenheit.
