Have you ever noticed that environments tend to stay the same as long as certain conditions remain in balance? For example, a forest will remain a forest as long as the temperature, rainfall, and soil conditions are suitable for trees to grow. However, if one or more of these conditions change, then the environment will also change in order to reestablish balance.

These changes can occur slowly over thousands or millions of years, or they can happen more quickly. For example, climate change can cause an area that was once a forest to become a desert, as the temperature and rainfall patterns change. This process can take a long time, but it can have a significant impact on the plants and animals that live in that environment.

Another example of slow change is the formation of a mountain. When a mountain forms, it can alter the local climate by blocking the movement of warm and cold air masses. This can cause the area on one side of the mountain to be much cooler than the area on the other side. For example, the side of a mountain that faces away from moving air masses might be much dryer and receive less rainfall than the side of the mountain that faces toward moving air masses. This is known as a rain shadow.

Overall, it’s important to understand that environments are always in balance, and that changes in one part of the environment can have a ripple effect on other parts of the environment. By studying these changes, we can learn more about how environments work and how they are affected by different factors.
