Mrs. Mysak’s students were studying a model of the major Texas rivers Mrs. Mysak’s students were studying a model of the major Texas rivers. The model showed the level of the rivers during each season of the year. The students observed that the level of the water in all the rivers was lower in the months of July, August, and September. What conclusion can the students make? A Evaporation occurred and lowered the levels of the rivers. B Condensation caused the levels to be lowered. C Run off from the mountain snow caused the levels to rise. D Heavy rains happened during the summer months.
