Current predictions of rainfall change in the west have indicated that rainfall may decrease by as mucj 40 cm in some areas. imagine a chaparral location that experiences 100 cm of average annual rainfall and an average annual temperature of 10 c. if there were a decrease in rainfall of 40 cm per year, what would you expect ?
a)the area under the curve for chaparall would shift to the left.
b)the area under the curve for chaparall would shift up.
c)the region would still be classified as chaparall because rainfall did not change.
d)the region would become a temperate grassland/desert.

D)The region would become a temperate grassland/desert.

Explanation:

Chapparal locations have specific amount of rainfall that is around 45cm to 65cm. If the rainfall continue to decline then there would be scarcity and the region could convert into desert or temperate grassland because they require less amount of rainfall per year.

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
