Correct answer: Magnetic field is created when molten material is heated from earth's core.
Due to the movement of molten iron and nickel inside the core of the earth magnetic field is generated. Due the the generation of high temperature all the molten material are in the liquid form. A Coriolis force is generated due to flow of molten liquid, which result in the formation of magnetic field.
The magnetic field of the earth is used to protect the earth from the harmful solar radiation .
Plate tectonic theory can be made up of two things. The two things
that it is made of are all oceanic lithosphere or all continental
lithosphere.
Nuclear Membrane
The nuclear membrane is a double layer that encloses the cell's nucleus, where the chromosomes reside
Answer:
Use the rule that 10% of the energy is transferred between layers.
Explanation:
Energy is transferred between layers of a food pyramid. That means that the producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).
However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers
