Answer:
Compare and Contrast the relationships between the speed of electromagnetic  and mechanical waves as they travel through different mediums is explained below in details.
Explanation:
As per the mechanism, the waves can be distinguished as electromagnetic and mechanical waves. Electromagnetic waves are those fluctuations that have no mechanism to progress whereas mechanical waves demand a mechanism for their communication. Electromagnetic waves progress in a vacuum whereas mechanical waves don't have.
 
        
             
        
        
        
Answer:
temperature 
Explanation:
I choose temperature because it tells how hot,cold,dry and warm somethings are meanwhile evaporation is when water changes from liquid to gas,so that means water gets hot.
 Precipitation is when water released from the cloud to form rain,freezing rain,sleet,snow,or hail.Which means thing get cold.
Air pressure also affect evaporation, which means that water will not be able to come up of the surface of a body of water.So that means the the pressure will be pushing down on the surface of the water.
 
        
             
        
        
        
The correct statements are-
Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity. 
When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface. 
Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.
