3 - 43 mi thick, surface temperatures	about 1,800 mi thick, 1,000 degrees C	about 1,300 mi thick 3,700 degrees C	about 800 mi thick, 4,000 C
made of the solid rock and soil that you can see, and also the floor of the ocean	top part is solid but the inner part is so hot that some of the rocks are soft and nearly melted.
