Marine science explores the oceans of the Earth. Tutors in marine science will help students develop an understanding of the history of oceanography, the formation of the earth, geological oceanography, chemical oceanography, physical oceanography, and/or biological oceanography. Tutors may also help students study concepts that include but are not limited to: plate tectonics, continental margins, ocean basins, sedimentation, the formation of the seafloor, properties of the water molecule, the structure and properties of seawater, and dissolved gasses in seawater.
