the difference in altitude represented by the space between two contour lines on a map. At least i think youre looking for the definition. And if you are hope this helps :)
 
        
                    
             
        
        
        
Answer:
true
Explanation:

I am pretty sure that it is D 
With decomposition, the final deposition of particles(sediments) usually occurs at the mouth of a stream. Then a process called horizontal sorting occurs where the sediments that were once carried down are arranged from big to small. Decomposition in streams takes time so the speed of the water and wind should not affect it nor should gravity or the direction. Streams cannot change direction either unless human involement occurs 
Hope this helps :)
 
        
             
        
        
        
Given what we know, we can confirm that the principle from the cell theory that supports this finding is that existing cells are produced by other living cells.
<h3>What is the cell theory?</h3>
The cell theory is a scientific theory proposed in the middle of the 19th century. It attempts to explain the formation and role of cells. There have been many wrongful iterations of this theory until arriving at the current version that is widely accepted today. 
Therefore, we can confirm that the principle from the cell theory that supports this finding is that existing cells are produced by other living cells.
