terrestrial origins

Terrestrial origins refer to the idea that certain elements, molecules, or compounds originated on Earth's surface or within its crust, rather than arriving from space. For example, some chemicals found in sediments or soil may have formed through natural processes like weathering or biological activity. This concept helps scientists understand the source of materials in our environment, distinguishing between substances created locally versus those delivered by external sources such as meteorites or cosmic dust. In essence, terrestrial origins identify how and where specific compounds or elements naturally developed on Earth.
