The basic elements that make it up! For example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. Which of the following is an example of a chemical change?

Which of these best describes how the lungs and diaphragm affect each other?

A

Find the hot spot on the map. This represents one of the volcanoes of Hawaii, which gets its fuel because the island sits over a hot spot. Hot spots occurs at abnormally hot centers known as mantle plumes.

This type of volcanism, hot spot volcanism, is unique. Why?

A The hot spot volcanoes rarely result in mountain building; they are a destructive process.The hot spot volcanoes rarely result in mountain building; they are a destructive process.
