Answer: A. Radioactivity
Explanation: Internal heat is a feature of planets and other celestial bodies, such as stars and others, and according to some scientific claims, even some of the asteroids had internal heat in the early stages of the solar system.
The most important internal heat source of the earth and the other planets is certainly radioactivity, which means that the natural radioactive decay of radioactive elements in the earth releases heat, which as such is the most significant internal heat source. The reaction of radioactive decay emits heat; more precisely, the radiation energy of radioactive particles induces the movement of atoms and the increase of their energy, and this increase in energy means heat.
It is known that gravitational force acts not only on earth but also on other celestial bodies, so this force is also an important source of the inner heat of celestial bodies. There are also geothermal energy sources on earth, and many others mentioned.
The correct answer will be “C”
You must write the speech like an essay, but minimize the use of speaking like this: Hi! My name is Emma! Today, I'll talk about this! No no, you cannot start speeches like that! You must state your thesis in your commencing sentence, and restate it at the end. Now that we have your introduction and conclusion, let's start the body of the speech. Your speech must have equal parts of loving people and prayers, nothing else. I mean it when I say nothing else, this speech isn't about anything OTHER than loving others and prayers. Going off topic can ruin a perfectly good speech, it's alright to go a little off topic; just as long as you very directly back to the point. So remember, a good introduction and conclusion and a few paragraphs on your topic; just don't have any run on sentences in your speech either.
