Answer:the first one is external stimulus
And the second one is migration
Explanation:
90 degrees is the maximum latitude - (90 degrees N - this is at the North Pole, and 90 degrees S - for the South Pole).
<em>So, 90 degrees N and 90 degrees S are the latitudes where is most likely to see glaciers.
</em><em />
<em></em><em>** Degree - mean " </em><em>° ", </em><em>So, you can write 90 degrees N as 90° N ** </em><em>

The larger the frequency, the shorter the wavelength. if the wave length increases, the frequency goes down.
Our energy supply comes mainly from fossil fuels, with nuclear power and renewable sources rounding out the mix. These sources originate mostly in our local star, the Sun.
<u>Answer:</u>
<em>The wholesale removal of sediment by wind is called </em><u><em>deflation</em></u><em>.</em>
<em></em>
<u>Explanation:</u>
Deflation is the phenomenon of displacement of small particles, seeds and other finer grains by wind. The materials which are carried and deposited are called the sediment.
In areas where deflation occurs, only big rocks are visible. The only fine particles of materials are hidden by these big rocks.
Desert pavements are the result of deflation. Desert pavements consist of big rocks and other solid fragments since smaller fragments have been eroded in deflation. The fragments left behind remain consistent hence, desert pavements remain stable over time.
