The answer is; C
In folding, when segments of Earth's crust are bent and doubled over, the sediments in between are form folds, since they are forced into a smaller space.  This also occurs in converging plates boundaries.
Block Mountains occur when stress due to compression in the crust causes the hanging wall between a fault to move up relative to the footwall. 
 
        
                    
             
        
        
        
Kelvin. Kelvin is the scientific term used in temperature senses, and was created so everybody around the world would have the same measurements and not get confused about whether it was Fahrenheit or Celsius.
 
        
                    
             
        
        
        
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
 
        
             
        
        
        
Answer:

Explanation:
