While jogging barefoot on the beach, georgio steps on the sharp edge of a broken shell and immediately lifts his foot. what causes georgio to immediately lift his foot in response to the shell? a. sensory neurons relay information directly to the spinal cord and motor neurons in the spinal cord send information to muscles in the foot. b. sensory neurons relay information directly to the brain and motor neurons in the brain send information to muscles in the foot. c. motor neurons relay information directly to the spinal cord and sensory neurons in the spinal cord send information to muscles in the foot. d. motor neurons relay information directly to the brain and sensory neurons in the brain send information to muscles in the foot?

B

Explanation:

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 !

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
