For your geography project on “Diversity of Environments That Support Life (Land, Air & Water)”, you can briefly write:

Life on Earth is supported by diverse environments such as land, water, and air. Land includes forests, deserts, grasslands, and mountains, each providing habitats and resources for different organisms. Water environments like oceans, rivers, and lakes sustain aquatic life and provide drinking water. The air supplies oxygen and carbon dioxide essential for life. Together, these environments interact to maintain the balance necessary for all living beings to survive.
