How are electromagnetic waves different from sound or water waves?
Annette [7]

Explanation:

Electromagnetic waves are different from sound or water waves in such a way that water and sound waves are called mechanical waves that requires a material medium for their propagation.

Electromagnetic waves do no require a material medium for propagation.

  • Electromagnetic waves are carried or transported by radiation and this can be passed through vacuums and different other materials.
  • But mechanical waves such as water and sound waves requires a material medium for their propagation.
  • They cannot pass through a vacuum.

PLEASE HELP!!!!
VashaNatasha [74]
In my opinion I would say all of the above; because people's job depends on where they live or how their environment is. The way they travel is also affected because we can't travel by car through water and can't use a boat in land. Free time as well because people like to travel and or just stay at home depending on the weather which is part of earths features.

How does water form in the clouds? Explain how
Aloiza [94]

When air rises in the atmosphere it gets cooler and is under less pressure. When air cools, it's not able to hold all of the water vapor it once was. Air also can't hold as much water when air pressure drops. The vapor becomes small water droplets or ice crystals and a cloud is formed.

I hope this helps you..
