18 The Florida panther, a subspecies of cougar, is
an endangered organism and may become
extinct. Which of the following is NOT a reason
why the Florida panther may become extinct?
A. There are more deaths due to car impacts now
because of the increasing human population,
B. There are few adaptive traits that allow the
panther population to survive in a quickly
changing environment
There is more aggression and death among the
limited number of panthers due to limited
resources
D. There is an increased reproductive rate that now
causes too much competition between the
Florida panthers.

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 !

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.

hope it ,
