If you increase the surface area of a rock, how will it affect the rate at which it weathers? a. It will weather more quickly. b. It will have no effect because surface area is not a factor in weathering. c. It will weather more slowly. d. It will have no effect because a rock does not have a surface area. Please select the best answer from the choices provided A B C D PLEASE HURRY

A

Explanation:

A rock's exposure to the weathering elements and its surface area can affect its rate of weathering. Rocksthat are constantly bombarded by running water, wind, and other erosion agents, will weather more quickly. Rocks that have a large surface areaexposed to these agents will alsoweather more quickly.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
