Earth's atmosphere plays a crucial role in creating suitable conditions for living things by trapping heat through the greenhouse effect, which helps maintain a stable temperature. Additionally, the atmosphere filters harmful solar radiation, such as ultraviolet rays, while allowing essential sunlight to reach the surface. The presence of oxygen in the atmosphere enables respiration for many organisms, supporting life on Earth.
In "The Earth is a Living Thing," the Earth is compared to various living things such as a rose, a cell, a tree, and a spider. These comparisons are used to illustrate the interconnectedness and interdependence of all living beings with the Earth.
The three conditions that make life on Earth possible are: presence of liquid water, suitable temperature range, and presence of a stable atmosphere with oxygen.
The atmosphere is a layer of gases surrounding Earth. It extends up to about 600 kilometers (372 miles) above the Earth's surface.
No, earth science primarily focuses on the study of non-living things, such as rocks, soil, and natural processes like erosion and plate tectonics. The major branch that deals with living things is biology.
