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:
Normal fault
Explanation:
Tensional stress occurs as a result of forces which could be wind, water etc pulling the rocks apart and forming faults. Faults are also known as a type of fracture which occurs between rocks.
Tensional stress along a fault can result in a dropped hanging-wall block relative to the footwall side(in a perpendicular position) thereby producing a normal fault.
Answer: Indonesia
Explanation:
Archipelago- a group of many islands
Indonesia is the largest archipelago in the world
There are total number of 17,508 islands.
Answer:
is caused by earth's rotation
Explanation:
- The Coriolis effect is the direct result of the earth's constant motion around its axis and in which he objects are deflected towards the right in the northern hemisphere and to left in the southern hemisphere. It is also called as an initial or fictitious force with reference to clockwise rotation.
