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 .
Destruction of the forest results in the disappearance of the species in this forest, which might not be found in other forests. This means that some species will become extinct. Extinction of species leads to reduction of biodiversity - the correct answer is the first one: forest destruction will <span> reduce biodiversity and remove organisms with the potential to help humans</span>
In a series of reactions the energy is converted (along an electron transport process) into ATP and NADPH. Water is split in the process, releasing oxygen as a by-product of the reaction.
