Students were exploring a coastal area close to their high school. the rocks along the coast are limestone. besides being very smooth, there were numerous circular holes in the limestone rocks. the students hypothesized that the circular holes were caused by wave action. what would you say to the students about their hypothesis? a) the circular holes were caused by organisms that live in and around the rocks. b) abrasion by boats and other debris mechanically weathered the limestone rocks at the coast causing the circular holes. c) the students are correct. wave action is a type of physical weathering that caused the circular holes in the limestone rocks. d) the circular holes were caused by chemical weathering of limestone with ocean water rather than physical weathering by

answer; ///i believe the correct answer is (aids) acquired immune deficiency syndrome;

to figure the total magnification of an image that you are viewing through the microscope is really quite simple. to get the total magnification take the power of the objective (4x, 10x, 40x) and multiply by the power of the eyepiece, (usually 10x)

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
