Please help me Scientists have tracked the changes in this land for many years. Picture A shows how the land looked to start with. Many years later, the land looked like Picture B. What MOST LIKELY caused the change in the land?
A)a coastal glacier
B)water cutting the rocks
C)wind blowing in circles
D)earthquakes along the shore

D) earthquakes along the shore

Explanation:

Movement of tectonic plates are responsible for reshaping the surface of our planet and it is contributed by earthquake sometime.

High richter scale of Earthquake allow tectonic plates to slide over each other or collide with each other of Earth's crust within a geologically period of time and causes the rising or sinking of the land.

As the image shows uplifting of land and sinking land in picture B, the action is performed by earthquakes along the shore.

Hence, the correct option is D) earthquakes along the shore.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
