Auranium atom absorbs a neutron and transforms into a zirconium atom, a tellurium atom, and three neutrons. this is an example of a. fusion b. fission c. a chemical reaction d. both fission and fusion

The correct answer is B.

Nuclear fission is a reaction in which a heavy atom splits into two or more atoms whereas in fusion, two lighter atoms combine to form a different atom.

In nuclear reactions, a change in atom's nucleus is involved which causes it to change into other element. Whereas in chemical reactions, rearrangement of electrons is involved and there is no change in the nucleus of the atom. Therefore, the given reaction is nuclear fission.

explanation:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
