Hi!
Rock pools are exactly what they sound like. They are rocky pools by the sea. They are usually found in the intertidal zone. During the occurrence of a high tide, they are filled with seawater. During low tide, they usually become/exist as separate pools.
Hope this helps, have a wonderful day/night!
Answer:
The process where organisms naturally go and adapt to enviroment where they can most likely survive and produce more offspring.
Explanation:
Theory was first made by Charles Darwin and is now believed to be the main process that brings about evolution.
Richter's original magnitude scale (ML) was extended to observations of earthquakes of any distance and of focal depths ranging between 0 and 700 km. Because earthquakes excite both body waves, which travel into and through the Earth, and surface waves, which are constrained to follow the natural waveguide of the Earth's uppermost layers, two magnitude scales evolved - the MB and MS scales.
The standard body-wave magnitude formula is
MB = log10(A/T) + Q(D,h) ,
where A is the amplitude of ground motion (in microns); T is the corresponding period (in seconds); and Q(D,h) is a correction factor that is a function of distance, D (degrees), between epicenter and station and focal depth, h (in kilometers), of the earthquake. The standard surface-wave formula is
MS = log10 (A/T) + 1.66 log10 (D) + 3.30 .
There are many variations of these formulas that take into account effects of specific geographic regions so that the final computed magnitude is reasonably consistent with Richter's original definition of ML. Negative magnitude values are permissible.
Answer:B is the right answer I am sure.
