Weathering and Erosion
Well my favorite activity in weathering and erosion is the atmosphere project. because i learned a lot of things that are interesting.Like the atmosphere is mostly filled with nitrogen about 78% and only 21%oxygen and last but not least 1% trace gases.Also scientist say the temp. will go up 6 to 7 degrees in the next one hundred years.
