A rocky hill cracks after water settles and freezes. Several trees on the hill tilt due to the very slow downhill movement of rock and soil. The movement occurs over a long distance.Which type of mass movement does this describe?

Creep is the very slow downhill movement of soil and rock over a long period. As the ground gradually shifts, it can tilt trees on a hill. A landslide, slump, or mudflow moves more rapidly, so creep best matches the description.
