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:
Removing American Indians will allow white settlers to become wealthier.
Explanation:
Trees take in carbon dioxide and other gases that we cannot breathe in and gives us oxygen. It also helps other plants and animals nourish themselves. To some animals, trees are their habitat so by planting more trees, we are technically building a habitat for plants and animals to live in. It's also good shade on a sunny day.
