Why is the core liquid?
Inside the Earth, its interior temperature drops, while its pressure remains constant. ... So the Earth's core is liquid because it's hot enough to melt iron, but only in places where the pressure is low enough.
Which is the thickest layer?
MANTLE
Out of them, the mantle is the thickest layer, while the crust is the thinnest layer. The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer, while the crust is the thinnest layer.
