Well, Binary Stars, and Gamma Ray Bursts may be worth an investigation. As would be the Cepheid Variables, those famous stars that first gave us a yardstick with which to measure the size of the Universe!
And have a crack at Henrietta Swan Leavitt while you are at it. A much overlooked scientist.
The sun will one day blow up like all of the other stars and we will all die but that's not for a long time. Then the some will be born again and we will again have life on Earth. It is a cycle.
Differentiation occurred in other inner planets, besides Earth.
The most obvious solar cycle the sunspot cycle, of roughly 11 years (on average - the length of an actual cycle may vary). Once in every sunspot cycle, the Sun's magnetic field reverses (north become south, and south becomes north), so a full cycle (for north to be back where it started) is twice the sunspot cycle.
Keeping track of where and when tornadoes occur, among other things, helps verify the accuracy of predictions. Patterns in tornado occurence are also useful in risk assessment.
Dust... :) and other things you know... :\
A cycle never ends so therefore it doesn't stop. Also percipitation, condensation, and evaporation always occur due to the Sun and many other things.

they both occur in the biosphere.
Three reasons are: 1. The living things can be used for fertilizer. 2. They can help move nutrients to other living things, continuing the natural cycle. 3. When the living things die, others can decompose them, and the cycle will go on.
people and other living things get carbon from the continuous exchange of carbon among living things (the carbon cycle).
All stars that are converting hydrogen into helium via nuclear fusion are said to be on "main-sequence". See related question for more information
Variation occurs because of mutations in the genetic code.Mutaions occur when one of the nitrogen bases are in the wrong spot like if aa is next to each other in the wrong sequence then the mutations occur
An ordered set. It could be an ordered set of numbers, or of events or other things.
It is a cycle on how carbon dioxide is transformed into oxygen for animals and humans and other living things to breathe.
people, animals, cells and other micro organisms that dwell on living things
yes see, if it takes two years for a female cow to give birth and then the other year it can have another you figure it out the rest.
Cancer cells have lost the ability to regulate their cell cycle among other things.
