Which elements are found in a high proportion in earth’s crust?

Only eight elements—oxygen (O), silicon (Si), aluminum (Al), iron (Fe),calcium (Ca), sodium (Na), potassium (K), and magnesium (Mg)—constitute more than 99% of its volume. In the earth's crust, these elements generally form crystalline solid compounds of de finite chemical composition which are known as minerals. hope i helped

 The most common chemical elements in the crust are oxygen, aluminium, 
iron, calcium, potassium, sodium, and magnesium ;)

Evidence peice 1: millions of years ago existed the supercontinent pangea after millions of yearsnit broke into peices and formed smaller continents and islandsevidence peice 2: there is a massive fault line in san fransico and california that has the potential to cause massive earthquakes which supports the theory of fault linesevidence peice 3: mountains are said to be formed by earths tectonic plates crashing against each other for millions of years and eventually if forms a big point know as a mountain.evidence peice 4: the mariana trech is the deepest place (so far) discovered in the oceans of earth. it is so deep that you can literally see how earths plates are divided and or continents as well
