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.

Two human activities that increase the rate of erosion include farming and deforestation. Both make the top cover of the soil loose making it very easy for it to be carried away by agents of erosion such as wind and water. On the other hand, two natural events that can lead to increased <span>erosion rate include floods and earthquake.</span>

<h3>Answer: </h3>
A knickpoint is a steep section of a river's profile that can range in size from a single waterfall to a multi-kilometer high-gradient region.
Answer:
one type of coniferous forests, the northern boreal forest is found 50° to 60°N latitudes... conifers tend to be evergreen, that is,they bear needles all year long. These adaptations help conifers survive in areas that are very cold or dry.
Explanation:
