Your question as written makes little sense.
There are chemical changes taking place constantly on earth and beyond.
Grilling milkfish is a chemical change because the heat causes the proteins in the fish to denature and undergo chemical reactions that change its composition and flavor.
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
It is a chemical process. The diesel gets compressed with air which in turn causes heat which in turn causes combustion.
Hormones
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.

weathering from mechanical and chemical means the process is causing the rocks to become smaller and smaller each time :)
Yes. The charging causes a chemical change in the electrolyte of the battery.

The tilting of the earth causes a change of seasons.

Erosion is something that causes the earth's landforms to change.
The rotation of the Earth
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
the rotation of the earth around the sun
