Hello,
Here is your answer:
The proper answer to this question is option C "<span>According to the method of their formation".
Here is how:
Scientist's figure out what type it is due to the method they use to figure out what type of rock it is.
Your answer is C.
If you need anymore help feel free to ask me!
Hope this helps! </span>
<span>Prior to the Cambrian, organisms with hard parts (eg. shells and bones) weren't present for most the time, and it's generally such hard parts that get to fossilize. There's also been more time for Precambrian deposits to get destroyed by natural processes, </span>
<span>The supply of Precambrian fossils has actually greatly improved over the last few decades. The so called Ediacaran faunas have been found at many parts of the world, and would be worth looking into.hope it helps</span>
"Erosion will increase, carrying more sand away than before" will most likely result.
Option A
<u>Explanation:</u>
Erosion occurs when the sea area is consumed. There are five main mechanisms that cause coastal erosion. There is corrasion, hydraulic performance, abrasion, oxidation and solution/ corrosion.
Corrasion occurs when the waves remove dirt from the floor (like pebbles) and rotate it at the bottom of the rock. The shoreline is usually longer. Softer areas are covered with sediment from hard areas and rocks are removed.
Answer:
0.35 m
Explanation:
Constructive interference occurs when the difference in the distance between the two speakers is
0, λ, 2λ,...
Here λ = v/f = 343/490 = 0.7m
The first point of interference is the initial point which would mean the distance is the trivial solution of 0 .
A microphone is placed half-way between the speakers and then moved along the line joining the two speakers until the first point of constructive interference is found.
Let x be the distance from the midpoint to the next interference.
This occurs when 1.5 + x -(1.5 - x) = 0.7
so 2x = 0.7 which means x = 0.7/2 = 0.35m
