Why Is The Interior Of The Earth So Hot
The earth was formed by the process of accretion.
Why is the interior of the earth so hot. The heat from when the planet formed the heat from the decay of radioactive elements. The amount of heat energy is proportional to the mass or the volume since mass is proportional to volume. We are also going to review concepts such as convection conduction and radiation.
We know how hot the interior of the earth might be because of laboratory experiments and also volcanic eruptions. Another reason why the earth is so hot is that mantle convection is a very inefficient way to transport said heat and thus the earth loses energy very slowly. It is thank to the continous nuclear fission of elements in the earth s interior that replaces the heat the earth loses keeping it nice and hot.
The interior of earth is very hot the temperature of the core reaches more than 5 000 degrees celsius for two main reasons. Earth s interior is generally divided into three major layers. The bottom line here is simply that a large part of the interior of the planet the outer core is composed of somewhat impure molten iron alloy.
Added to this rocks are bad conductor of heat. The deepest layer is a solid iron ball about 1 500. In this video we are going to explain why the earth s interior is hot.
The melting temperature of iron under deep earth. If you heat one end of a 1 meter long cylindrical rock mass of radius 1 cm it will take thousands years to transfer the heat to the other end. The rate of heat loss is proportional to the surface area.
The earth is still so hot inside in large part because its surface is too small relative to its volume for this heat to escape. The earth s interior is composed of four layers three solid and one liquid not magma but molten metal nearly as hot as the surface of the sun. Just compare it with an iron rod of same dimension that is why the interior of earth is still so hot.
