Why are the melting temperatures of most ionic compounds far greater than the melting temperatures of most covalent compounds?
A. Covalent bonds are not as strong as ionic bonds. B. Most covalent compounds have at least one weak bond in their structure that is easily broken when heat is added. C.

Explain how radioactive decay has always warmed the earth from the inside, and nuclear fusion has always warmed the earth from the outside.
A. The inner Earth is made of fissioning heavy elements, while the sun is made of lighter fusing elements. B. Much heat was released as matter coalesced to form the earth. This heat resulted in the production of radioactive isotopes, which still reside within the earth today and are a source of internal heat. Our primary external source of heat is from the fusion of hydrogen within the sun. C. Radioactive elements have been within Earth since it was created while the sun is made of fusing hydrogen atoms. D. All of the above are reasonable answers.
