1) do the elements that make up the earth's crust occur mostly as elements, or do they occur as compounds? explain
2) do the mantle and the core of the earth have thesame chemical make up as the crust? explain
3) note that approximately 1.5 % of the earth's crust consists of "all other" elements. Name three common elements that fall into this category.
4) Do you think that all the planets in the solar system have a composition similar to that of the earth? explain.

1. Compounds. The crust is the outer layer it's roughly 60% silica which is not an element.
2. The mantle and core are of completely different composition due to great presure and heat. Theoretically the core is mostly molten iron and nickel.
3. The 8 most common in order of volume from greatest:
Oxygen
Silicone
Aluminum
Iron
Calcium, sodium, potassium, magnesium
4. No! Only earth has oxygen in great quantities. Making water possible in great volume. The remaining composition is not that greatly dissimilar though.
10pts please!
