Science Class 12/8 week

On Monday, in class we made a hypothesis that said when we studied the big mountain chain on the maps, when the two plates collided the plates sprouted upward and created mountains.  Also, over time water and wind have decreased the height of the mountain.  Then for homework we had to answer the question that said can chemicals also affect a mountain.  Our group said that it could because if there was acid rain, and there were rock types in the mountain that were vulnerable to a chemical reaction, then it would change.  Then, on Thursday we had a quiz on topography.  Finally, on Friday we conducted an investigation with chalk and hydrochloric acid.  We had 3 different sizes of chalk in 3 seperate bowls, and we poured the acid into it, and it kept bubbling for almost 15 minutes.
