Introduction
We often think of the Earth as a stable and safe place to live. The landscape we see seems timeless and impossible to influence. At the same time, we know there are a lot of forces that affect our planet and change it. Some changes are quick, such as when earthquakes and volcanic eruptions break the ground or covering it with lava. Other changes may take millions of years, such as wind or the abrasive forces of water.
The hunt for food, searching for land to cultivate, etc. has always pushed the man to explore the earth. Exploration for natural resources, metals and riches, as well as for scientific truth, to reveal the secrets of nature has always pushed the man forward. These are some reasons why the Earth has changed as much as it did until today.
The geology has evolved into one of the most important contemporary sciences, perhaps of greatest importance for our everyday life.
What affects the climate on our earth? What causes earthquakes? What does our future look like? How has Earth changed through time? It is here I will try to answer it in my work.
Building forces
The building forces are driven by energy from within the earth. There are movements in the earth's interior, in the mantle, which allows different crustal plates to constantly move and change. When two plates collide with each other, it cracks and mountain chains are formed. Meanwhile the constructive forces are also the ones that create the deepest oceans. When two plates collide and one of them is pressed for the second plate, a deep-sea tomb is forming. The plates move very different, some only a few centimetres per year, others can move decimetres per year. One effect of plate movement is that it along the cracks in the crust it is common that it will be earthquakes and volcanic eruptions.
The vegetation exchanger
As the climate has changed, means that also plant propagation has changed. For about 6000 - 7000 years ago, the climate in Scandinavia
