Look over the region and examine the mountains, note their shape, ground cover, and height. How do these mountains compare to the Rocky Mountains (search for 43 48 25.03N 110 50 26.19W to examine Grand Tetons National Park)?a. The Shenandoah mountains are shorter. b. The Shenandoah mountains are more rounded. c. The Shenandoah mountains have more vegetation. d. All of the above.

What are similarities and differences between refraction, reflection, diffraction and absorption?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
