Earth and Atmosphere

What are the changes in the Earth and its atmosphere?The Earth and its atmosphere provide everything we need. The Earth has a layered structure. Large-scale movements of the Earth's crust can cause changes in the rocks. The Earth's atmosphere was originally very different from what it is today. It has been much the same for the last 200 million years and provides the conditions needed for life on Earth. Recently human activities have produced further changes.
