The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.

Answer:
Because of the fertile plains of the Danube River.
Explanation:
Slovakia and Czechia (formerly the Czech Republic) despite being part of a single country until three decades ago, and being neighbors with very close ties, have developed differently and their economies have a lot of differences. One of the biggest differences is that Slovakia has a highly developed agricultural sector while Czechia's is very small and doesn't contribute much to the economy.
s The reason for this difference is geography. Slovakia has a relatively large and very fertile plain, with the Danube River being a big plus in it. This provides Slovakia with enough area and very good conditions so that it can have a prosperous agricultural sector. Czechia, on the other hand, is almost entirely covered with mountains and hills, and the little area of the handfull of valleys is mostly urbanized, thus the country doesn't have what it needs to develop the agricultural sector.
Answer:
Unconformities Are Gaps in the Geological Record
Gaps in the geological record, like those discovered in 2005, are called unconformities because they do not conform to typical geological expectations.Explanation:
Answer: Appalachian Mountains, Rocky Mountains, Great Lakes, Lake Superior, Missisippi River, Great Plains, Silicon Valley, Atlantic Ocean, Pacific Ocean, Mount McKinley.
Explanation: Sir I'm pretty sure you could've just looked these up, but those are all the Geographic features I can think of,
