Plate tectonics.
An asteroid impact caused a mass extinction about 65 million years ago
This climate change is different:Because of its speed. Previous climate changes took many thousands of years, this has taken 200 years.Because it is being caused by human activity, deforestation and burning fossil fuels (coal, oil and natural gas).
The change from the last Ice Age till now. This took 12,000 years.The present climate change caused by the global warming that has been happening since the Industrial Revolution. This rapid warming has been most noticeable over the past 50 years.

why did the shape of a hairspray bottle change over the years
The current shape was first used in the 2008 models.
18 years old.
100,000 and 400,000 years, caused by changes in the shape of earth's orbit around the sun.
The shapes do change, but only a little bit over thousands of years.
The Matterhorn was created through geological conditions commencing some 200 million years ago. The modern shape is caused by a million years of erosion
Ok? Go for it? lol
200 years ago there was an earthquake in Illinois that caused the flow of the Mississippi river to change direction
Obviously - Climate change
The actual boundaries of the constellations do not change, but because all stars are moving, the shapes appear to change. e.g. Ursa Major (the Big Dipper) will be a different shape in 100,000 years as the stars that comprise it are all moving relative to each other.
Shape. Erosion would change the shape of the tops of the mountains. It may also change in height a little, too.
There is no 'periodic' change in the earths orbit. The orbit is elliptical and over time (a great many years) becomes less so.
