VikaD [51]3 years ago
7 0

<u>ANSWER:</u>

  • About some billion years ago, dust and gas particles began orbiting around the sun.
  • These particles then began to stick together and formed large particles. Slowly, these particles began attracting more mass with their gravity.
  • After millions of years, these particles became planetesimals. They started revolving around the sun in their own orbit and formed spherical shapes.
  • This continued for another millions of years and thus planets were formed.

<u>EXPLANATION:</u>

  • The inner planets are the four planets that are closest to the sun. The inner and outer planets are separated by asteroid belts.
  • The "inner planets are terrestrial" and rocky whereas the "outer planets" are mostly gas.

Which of these lists is arranged in order from smallest wavelength to longest wavelength?
guajiro [1.7K]

Answer:

b. wind waves, seiches, tsunami, tides.

Explanation:

The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave.  Usually, the bigger the wave, the greater the wavelength.

wind waves: small waves caused by the wind.  These waves tend to be small and with a short wavelength.

seiches: are usually waves on a lake or other closed water bassin.  They can be pretty high from a human perspective, so they are definitely bigger than wind waves.

tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.

tides: yes, a tide can be considered as a huge wave... that's running throughout the planet.  We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.
